Explanation:

Normal Earth temperature means the standard temperature and pressure conditions. At STP, temperature is 273 K or zero degree celsius and pressure is 1 atm.

For gases at STP, volume is equal to 22.4 liter.

So, at normal Earth temperature sodium exists as a solid whereas oxygen exists as a gas.

On the other hand, both bromine and mercury exists as liquid at normal Earth temperature.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point)
iris [78.8K]

The true statement about the balanced equations for nuclear and chemical changes is; both are balanced according to the total mass before and after the change.

A basic law in science is called the law of conservation of mass. Its general statement is that mass can neither be created nor destroyed.

Both in chemical and nuclear changes, mass is involved and in both cases, the law of conservation of mass strictly applies.

This means that for both chemical and nuclear changes; total mass before reaction must be equal to total mass after reaction.

Hence, both reactions are balanced according to the total mass before and after the change.
