Explanation:

Anions and cations have different atomic sizes than the neutral atoms.

When the bromine atom becomes an anion, it ______ in size.

Anions involves gaining extra electrons. This basically leads to increased repulsion between the electrons and thereby increasing the size. Anions are always larger than the neutral atoms.

This means the answer is A. Increase

When the strontium atom becomes a cation, it ______ in size.

Cations involves losing valence electrons. This basically leads to a decrease in electron shells and electron repulsion thereby reducing the size. Cations are always larger than the neutral atoms.

This means the answer is B. Decrease

Which of the following statement is FALSE? a. Lowering the free energy of the transition state can increase a reaction rate. b.

ryzh [129]

Answer: Option (c) is the correct answer.

Explanation:

Activation energy or free energy of a transition state is defined as the minimum amount of energy required to by reactant molecules to undergo a chemical reaction.

So, when activation energy is decreased then molecules with lesser amount of energy can also participate in the reaction. This leads to an increase in rate of reaction.

Also, increase in temperature will help in increasing the rate of reaction.

Whereas at a given temperature, every molecule will have different energy because every molecule travels at different speed.

Hence, we can conclude that out of the given options false statement is that at a given temperature and time all molecules in a solution or a sample will have the same energy.

Energy Levels of an atom. Explain.

Flura [38]

Energy levels inside an are the specific that electrons can have when occupying specific orbitals. Electrons can be excited to higher by absorbing from the surroundings. Light is emitted when an electron relaxes from a high state to a lower one.

Calculate the bond length (in picometers) of a chemical bond between bromine and sulfur.

maria [59]

The bond length of a chemical bond between bromine and sulfur is 216 picometers.

<h3>Explanation:</h3>

Bromine and sulfur reacts with each other to form Sulfur dibromide.
Sulfur dibromide is a covalent compound which means that a chemical bond exist between them is covalent bond.
So, for finding a bond length of a covalently bonded compound we need to add the covalent radiuses of the two atoms.

Given,

Covalent radius of bromine is 114 pm;

and covalent radius of sulfur is102 pm.

∴ Bond length of the sulfur dibromide= Covalent radius of bromine + covalent radius of sulfur

∴ Bond length = 114 + 102

∴ Bond length = 216 pm.
