What was the experimental variable we tested in the lodine Clock Reaction?
Answer:Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while others occur over minutes, hours, or n over several years. What are the controlling in predicting if a reaction will take place and the speed at which it will? Thermodynamics can answer the question, "Will the reaction take place?" Once the reaction is capable of proceeding kinetics can answer the other question, "How fast You will study the rate of the reduction of potassium persulfate, KoS Os, with sodium iodide, Nal. The net ionic equation for the reaction is eve The rate law for this reaction is in the form of And you will need to determine the reaction orders a and b, as well as the rate constant, k. Keep in mind that exponents can not be determined by jus looking at the chemical equation the reaction will take place? The rate of a reaction is defined as the increase in molar concentration of product of a reaction per unit time or the decrease in molar concentration of reectant per unit time. The usual unit for the rate is moles per liter per sec (mol/L s or M/s). Experimentally, it has been found that a reaction rate depends on the concentrations of the reactants. Usually a higher reactant concentration increases chance of collision among the reactants per unit time causing a faster reaction rate. An equation describing the relationship between the reaction rate and the concentration of the reactants You will need a way to determine how much of the reactants were spent over the given time period. Preferably, the concentrations of the reactants should not change too much; therefore the reaction rate can be represented by the initial concentrations of reactants (the initial-rate method). In this experiment, we will couple another reaction that consumes the product, 12 very quickly. The new reaction is the reduction of is called a rate law. For the elementary reaction Note that l2, which was produced in reaction (1) is consumed as fast as it is produced by reaction (2) to regenerate two l. i.e. [门is kept constant. By keeping [S203-9 much smaller than the initial concentration of S,0, we can assure [S20,1 is also kept nearly constant when S203 is completely consumed. At this point, the 12 is no longer eliminated by the reaction and starts to accumulate. This point is signaled by sudden appearance of the dark color from the interaction of l2 with starch indicator. We can measure the time elapsed till the color appears Rate k [AIB] The proportionality constant, k, is called the ate constant in the relationship between the rate nd concentrations. The rate constant has a fixed alue as long as the reaction temperature is held nstant. The exponents, a and b, are called the action order, and are frequently, but not always, egers. More importantly, they must be termined experimentally In this experiment you will determine the rate an iodine clock reaction, and study the effects of perature and a catalyst to the reaction rate ugh there are several versions of an iodine k reaction, all of them share a common feature: completion of the reaction is signaled by the en appearance of a dark purple color. This is characteristic of the interaction between cular iodine and starch. When the reaction is ed out correctly, this color will appear so According to the reaction stoichiometries of reactions (1) and (2), two molecules of S203 are required to counteract the consumption of one molecule of S20a2. Since S2032 would have been completely consumed when the dark purple color appeared, the Δ[SO ] should be % of the initial concentration of S203 15-08-2] = ½ initial [S,03-21
When organisms die, how does carbon re-enter the environment?
I. Carbon dioxide released during decay
II. Carbon monoxide when the dead material reacts with oxygen
III. Forms sedimentary rocks
IV. Forms fossil fuels
A. II, III, IV
B. I, II, III, IV
C. I and III
D. I, III, IV
Answer:
Forms sedimentary rocks
When any organism die, it releases carbon dioxide during decay, forms sedimentary rocks as well as fossil fuels. The correct option is D.
What is carbon cycle?The carbon cycle is nature's way of recycling carbon, which travel from the atmosphere into lifeforms on Earth and then back into the atmosphere.
During decay, formation of sedimentary rocks, and formation of fossil fuels, carbon re-enter the environment after an organism die.
The carbon cycle exemplifies how carbon moves among various reservoirs on Earth. This cycle is crucial for keeping Earth's breathable atmosphere and carbon balance.
Without carbon, there wouldn't be any life on Earth. This is largely attributable, in part, to carbon's ability to readily form bonds with other atoms, which allows for greater flexibility in the form and function of biomolecules such as DNA and RNA.
Thus, the correct option is D.

Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)
Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots
Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.
Answer:
Na with 1 dot

How does latitude affect a climate zone?
A. Climate zones at high latitudes are cooler because they are closer to the equator.
B. Climate zones at high latitudes receive a lot of precipitation because they are farther C. from the equator.
D. Climate zones at low latitudes receive little precipitation because they are closer to the ocean.
None of the options is entirely correct about latitude and climate zone.
Latitude and climate zoneLatitude is one of the main factors that affect climate, along with elevation, ocean currents, and prevailing winds.
Generally, the farther away from the equator a location is, the colder its climate is. This is because the angle of the sun's rays hitting the Earth's surface is more oblique at higher latitudes, resulting in less heat being delivered per unit of surface area.
However, precipitation patterns are not solely determined by latitude. They are also affected by other factors such as prevailing winds, ocean currents, and topography. For example, areas located on the windward side of a mountain range tend to receive more precipitation than those on the leeward side, regardless of their latitude.
Therefore, while latitude is an important factor in determining climate zones, it does not fully determine precipitation patterns or temperature.

Some of the smallest cells in the human body are red blood cells. They make up nearly half the volume of blood. A typical red blood cell is 8 µm across. The largest artery that blood flows through is the aorta, which is about 20 mm (2 cm) across. How many red blood cells would fit side-by-side across the aorta? Show your working.
Answer:
[tex]$1.6 \times 10^{-3}$[/tex]
Explanation:
Given data :
Size of a typical red blood cells = 8 µm
= 0.0008 cm
The size of the largest artery through which the blood flows, known as aorta
= 20 mm
= 2 cm
Thus the number of the red blood cells that would fit side by side across the aorta would be = 2 cm x 0.0008 cm
= [tex]$1.6 \times 10^{-3}$[/tex]
While you and your little cousin are walking through a natural history museum, she points out the skull of an australopithecine with a large crest on the top and asks you what its purpose was. How might you correctly sum up this complicated evolutionary trait for your little cousin
Answer:
The purpose of the crest was to provide a surface for masticatory muscle attachment or insertion.
Explanation:
This crest is called the sagittal crest. It is present in extinct hominids, such as Australopithecus and Paranthropus, and can also be found in living animals such as gorillas or lions and some reptiles.
The sagittal crest is a bony structure that crosses the hominids´ skull longitudinally, and it is so well-developed that it stands out notoriously.
This crest, like others in the skulls, provides an attachment surface for many muscles. In the particular case of the sagittal crest, it is believed to provide an insertion area to mastication muscles.
It seems that Australopithecus had a special diet composed of tough items. The hominid probably needed to strong bite while eating. The strong jow muscles gave them the possibility to bite but needed a wide area for insertion. The sagittal crest provided that wide surface. There was a direct relationship between the size of the crest and the muscle mass. The bigger the crest was, the more developed the muscle was.
It is believed that in living animals, such as gorillas, the development of the crest in males is for sexual selection and reproductive success. The bigger the crest is, the more attractive the male is, and the more chances to be selected by the female to mate it will have. Some hypothesize that the development of the crest in Australopithecus could also be related to sexual selection.
