Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant?

Answers

Answer 1

Answer:

Answer: Avogadro's Law states that volume is directly proportional to the oles of the gas.

Explanation: Expression fro ideal gas equation:

$PV=nRT$

This law has arrived from the combination of four laws:

1) Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto (1)/(V)$ (At constant temperature and number of moles)

2) Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

3) Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$ (At constant volume and number of moles)

4) Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

$V\propto n$ (At constant temperature and pressure)

Hence, the correct answer is Avogadro's Law.

What is the charge on a fluorine ion? explain answer plz

Answers

-1

An ion is an atom which has gained or lost electrons.
Atoms want to have full outer shells of electrons.
Electrons are negative.
Fluorine has 7 electrons in its outer shell. When it gains one to fill its shell it will be made negative.
Thus the charge of a fluorine ion is -1

Which phase of matter consists of particles that are held together but have the ability to flow past each other?

Answers

Explanation:

In solids, molecules are held together due to strong intermolecular force of attraction between them. These molecules do not move past each other as they are fixed at their position. As a result, solids have definite shape and volume.

In liquids, molecules are less tightly held as a result the molecules are able to move and hence they slide past each other. Liquids do not have fixed shape and volume.

In gases, molecules are held by weak Vander waal forces. Therefore, they move rapidly from one place to another with more collisions.

Thus, we can conclude that liquid is the phase of matter which consists of particles that are held together but have the ability to flow past each other.

Which of the following is not a phase change?melting of snow
evaporation of water from the ocean
condensation of water vapor to form clouds
hydrogen and oxygen gas combining to form water vapor

Answers

Answer : The correct option is hydrogen and oxygen gas combining to form water vapor.

Explanation :

Phase change : It is a change from one state to another state without changes in chemical composition.

Phase change such as solid to liquid, liquid to vapor, vapor to liquid, liquid to solid, vapor to solid, solid to vapor.

Melting of snow is a fusion process in which phase changes from solid to liquid.

Evaporation of water from the ocean is a evaporation process in which phase changes from liquid to vapor.

Condensation of water vapor to form clouds is condensation process in which phase changes from vapor to liquid.

Hydrogen and oxygen gas combining to form water vapor, there is no phase change in this reaction because a gas combine with another gas to form a water vapor as a gas.

hydrogen and oxygen gas combining to form water vapor is the correct answer.

What do you think will happen to the ecosystem if all the coral reefs are destroyed?

Answers

Animals that rely on coral for protection and cover, such as grouper, snapper, oysters and clams, would also be negatively impacted. And because this marine life is a vital staple in many peoples' diets, the death of the coral reefs would exacerbate the problem of feeding these groups [source: Skoloff].
