When calcium carbonate is heated, it
decomposes into calcium oxide and carbon
dioxide. If 100 g of calcium carbonate are
decomposed, 56 g of calcium oxide is produced.
What would be the mass of the carbon dioxide
given off by the decomposition?
A. 448
B. 110 g
C. 156 g
Answers
Answer:
A. 44 g
Explanation:
First, you need to write a balanced equation:
CaCO₃ -> CaO + CO₂
Then, you need to find the molar mass of CaCO₃:
Ca = 40.078 amu
C = 12.0107 amu
3O = 47.9982 amu
_________________
100.0869 amu
Then, you calculate the moles of CaCO₃:
100 g ÷ 100.0869 amu = 0.9991 moles
In the balanced equation, we can see that the molar ratio of CaCO₃ and CO₂ is 1 : 1, so moles of CaCO₃ = moles of CO₂.
Now you need to find the molar mass of CO₂:
C = 12.0107 amu
2O = 31.9988 amu
________________
44.0095 amu
Finally, you can calculate the mass of CO₂ produced:
0.9991 moles * 44.0095 amu = 43.9698 g = 44 g

14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
data collection.
Answers
When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.
In the exposed example, Pincky is lacking theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.
---------------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.
When conducting an experiment, you need to consider,
• Definition and problem statement. The question for which there is not an answer yet.
• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.
• Data collection and analysis. This step involves testing the observations.
• Results
• Verification of hypothesis. This step involves the deriving of the working hypothesis.
• Discussion and Conclusion.
Previous knowledge about the study object is always required for a better understandig. A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.
--------------
So in this experiment there must be,
Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.
The goal: To know how temperature affects cricket´s chirping
Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.
Variables: Temperature → Independent
Chirp frequency → Dependent
Water and food supply, light exposure, refuge → Controlled
Study groups: group of crickets exposed to a warmer temperature
group of crickets exposed to a colder temperature
Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.
Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.
Results: Results should be clearly exposed, using texts, charts, and graphs.
Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.

Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

Options:
(1) 1. Nervous 2. Muscular 3. Skeletal
(2) 1. Nervous 2. Muscular 3. Skeletal
(3) 1. Skeletal 2. Digestive 3. Nervous
The answer is:Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) Nervous system first recognized the falling pencil. It sent signals to the (2) Muscular system, which then moved the components of the(3) Skeletal system in order to catch the pencil.
Explanation:
The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
Answers
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.
Answers
Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

There are multiple lines of evidence that provide support for common ancestry and evolution. Write 3-4 paragraphs
describing at least three of them in detail. Provide at least one example for each line of evidence.
<< Read Less
Answers
Answer:
Here's a better answer.There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.
In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.
Next up, the fossil record provides evidence that supports common ancestry and evolution. The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.
Explanation:
The various pieces of evidence that support common ancestry are homologous organs, fossil records and embryological studies.
What is common ancestry?The phrase "common descent" in evolutionary biology refers to a particular group of species' shared ancestry. The creation of new species from an original population is a component of common descent. Two creatures are considered to be closely related if they have a recent common ancestor.
In contrast, molecular genetic techniques can also be used to establish shared ancestry from a single universal ancestor of all living things. Natural selection and other factors, such geographic isolation, are considered to have contributed to many speciation episodes during this development from a universal common ancestor.
According to the common ancestry idea, every living thing descended from a single progenitor. Hence, the Theory of Common Descent contributes to our understanding of why traits in species living in different geographic regions vary, why some traits are highly conserved across broad animal classifications (such as vertebrates or tetrapods), why seemingly unrelated species (such as birds and reptiles) share hereditary physical and genetic traits, and why successfully adapted organisms typically have more offspring.
Therefore, embryological studies, fossil studies and homologous organs can help in the study of common ancestry.

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called A) micelles. B) liposomes. C) vacuoles. D) bilayer membranes. E) none of the above
Answers
Answer:
D) bilayer membranes
Explanation:
Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.
Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
