Other planets have an atmosphere, but Earth's is unique because it has large amounts of _____.nitrogen
oxygen
water vapor

Answers

Answer 1

Answer: Earth has large amount of oxygen, which allows life to thrive on it. Other planets have significantly lower amounts of oxygen. Others have high concentration of hydrogen, and carbon dixoxide. They also have a very thin atmosphere, and thus very unregulated temperatures,

Answer 2

Answer:

Other planets have an atmosphere, but Earth's is unique because it has large amounts of oxygen.

Atomic energy is the energy _____. in the nucleus of an atom of electrons and their shells in chemical bonds of elements and compounds

Answers

The correct statement to fill the blank would be the first option. Atomic energy is the energy in the nucleus of an atom of electrons and their shells. From the word atomic itself, we can say that this energy is energy within and carried by the atoms.

Answer:

in the nucleus of an atom

Explanation:

A chemical change involves the formation or the breaking of bonds. true or false

Answers

Answer: The given statement is true.

Explanation:

A chemical change is a change that causes change in chemical composition of a substance.

This change is due to the exchange of electrons that lead to the formation or breaking of bonds.

For example, sodium atom on donating an electron to chlorine atom forms an ionic bond due to transfer of electron.

This formation of ionic bond leads to the formation of a new compound named as sodium chloride.

Therefore, we can conclude that the statement a chemical change involves the formation or the breaking of bonds, is true.

Final answer:

Chemical change involves the formation or breaking of bonds, leading to the formation of new substances.

Explanation:

A chemical change involves the formation or breaking of bonds. When a chemical change occurs, the atoms rearrange themselves, leading to the formation of new substances with different properties. This is different from a physical change, where no new substances are formed.

Which statement describes how an atom in the ground state becomes excited?(1) The atom absorbs energy, and one or more electrons move to a higher electron shell.
(2) The atom absorbs energy, and one or more electrons move to a lower electron shell.
(3) The atom releases energy, and one or more electrons move to a higher electron shell.
(4) The atom releases energy, and one or more electrons move to a lower electron shell.

Answers

1) The atom absorbs energy, and one or more electrons move to a higher electron shell.

An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption.
The electron absorbs the energy and jumps to a higher energy level.
In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

So all the statements except 1) are false.

Which statement correctly describes a sample of gas confined in a sealed container? (1) It always has a definite volume, and it takes the shape of the container. (2) It takes the shape and the volume of any container in which it is confined. (3) It has a crystalline structure. (4) It consists of particles arranged in a regular geometric pattern.

Answers

A gas does not have a specific shape or volume (so we reject option A), instead it adjusts itself to the container (which is further influenced by other forces such as gravity and temperature) and it with time, willl fill the whole container evenly, so the correct answer is:
(2) It takes the shape and the volume of any container in which it is confined

Which statement describes a physical property of copper?It reacts with strong acids.
It can be reshaped by a force.
It ignites at high temperatures.
It can combine with oxygen.

Answers

Answer is: It can be reshaped by a force.

Physical property can be observed and measured without any changes in molecular composition. The same substance is present before and after the change, changing the shape is physical change.

Copper reaction with acid, ignition and combination with oxygen are chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

The correct answer is It can be reshaped by a force

That is because physical properties are ones that don't change the substance when it is physically altered. If copper is physically changed, none of its other chemical properties are influenced.
