Blanks: One Atom and Two Atom

Answers

Answer 1

Answer:

one atom, one atom.

Explanation:

Sodium chloride is made from one sodium atom and one chlorine atom.

Sodium has a charge of +1,  Chlorine has a charge of -1. These cancel each other out leaving only one atom for both sodium and chlorine.

Answer 2
The correct answer is one atom for each space

Organisms can either be made of one cell or made of more than one cell

Answers

Answer:

The statement is true.

Explanation:

Organisms can be unicellular (made up of one cell) or multicellular (consisting of more than one cell).

I hope this helps in any way :)

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

Why do scientists use models, and why do all models have limitations???
Plsss help! :) I will give brainliest!! :)

Answers

Answer:

Scientists use  models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.

Hope this helps :)

Answer:

Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.

Quartz, or silicon dioxide (SiO2), is one of the most abundant minerals on Earth. The diagram shows the atomic arrangement of quartz.

Based on the diagram, which statement best describes the atomic arrangement of quartz?
Group of answer choices

An extended structure that is made of repeating patterns of atoms.

A repeating pattern of small molecules that can move freely past each other

Many different kinds of molecules tha combine to form an extended structure.

Many different kinds of atoms that can move freely past each other.

Answers

Based on the atomic arrangement of quartz, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.

What is quartz?

Quartz is a hard crystalline mineral found within the Earth's crust and which is composed mainly of the mineral silica. Silica is mostly silicon(iv) oxide.

Quartz is colourless and its crystalline structure is of a hexagonal prism. The atoms are arranged in a regular repeating grid to form the hexagonal crystal.

Therefore, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.

Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.

pls make it simple and not write a whole paragraph

Answers

Answer:

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

Answer:

the law of conservation of matter

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.

C6H12O6 + 6O2 -> 6CO2 + 6H20

This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

Part 1: Name two elements that have the same properties as potassium (K). (4 points)
Part 2: Determine the number of protons, electrons, and neutrons present in an atom of magnesium (Mg). Explain how you determined your answer using complete sentences. (6 points)

Answers

Answer:

Part 1: Sodium and Rubidium.

Part 2:

Protons = 12

reason: protons are equal to the atomic number of an atom. For Magnesium, atomic number is 12.

Neutrons:

[tex] = { \tt{24 - 12 }} \\ = { \tt{12 \: neutrons}}[/tex]

reason: neutrons is given by formula:

[tex]{ \tt{neutrons = mass \: number - atomic \: number}}[/tex]

where mass number of magnesium is 24.

electrons: = 12 electrons

reason: Magnesium atom has electrons summing up to 12

part 1: hydrogen and sodium? my memory is so bad ngl

part 2: 36 because there are 12 protons, 12 electrons, and 12 neutrons in an atom of magnesium.

Energy transformations convert one form of energy into another form of energy such as in batteries where chemical energy is converted to electrical, light and heat energy.

What is energy transformation?

Energy transformations are changes which occur between different energy forms such that one energy form is converted to another form of energy.

Some examples of energy transformation are as follows:

electric fan converts electrical energy to mechanical energy generators convert mechanical energy to electrical energy electric cookers convert electrical energy to heat energy. chemical energy in batteries converted to electrical, light and heat energy

Therefore, energy transformation convert one form of energy into another form of energy.
