Chemistry

vodomira [7]3 years ago

Answer:

B. liquid to gas

Explanation:

Matter exists in 3 different states:

- Solid: in solids, particles in the substance are tightly bond to each other through strong intermolecular forces. Therefore, they can only vibrate around their fixed position, but they cannot move freely: as a result, the distance between the particles is the smallest among the 3 states of matter.

- Liquid: in a liquid, particles are able to slide past each other, however there are still intermolecular forces keeping them not too far from each other. As a result, in liquids, particles are on average more distance from each other compared to solids.

- Gas: in a gas, particles are completely free to move, as the intermolecular forces between them are negligible. As a result, in gases, the distance between molecules is the greatest, compared with solids and liquids.

Therefore, the phase changes in which the average distance between molecules increases is:

B. liquid to gas

1. Write the balanced equation for the decomposition of hydrogen peroxide
earnstyle [38]

The balanced equation for the decomposition of hydrogen peroxide is H₂O₂(aq)→2H₂O(l)+O₂(g).

<h3>What is decomposition reaction?</h3>

Decomposition reactions are those reactions in which a compound will decompose into small molecules.

Hydrogen peroxide will decompose into water molecule and oxygen gas, balanced chemical equation will be represented as:

H₂O₂(aq) → 2H₂O(l) + O₂(g)

Where all atoms are present in equal quantities on both side of the equation.

Hence balanced decomposition reaction of H₂O₂ is H₂O₂(aq)→2H₂O(l)+O₂(g).
