Explain how nuclear and chemical reactions differ in terms of how they are balanced. (PLEASE ANSWER ASAP THIS NEEDS TO BE TURNED
Tcecarenko [31]

Explanation:

(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxy
soldier1979 [14.2K]

The temperatures of the gases will not be equal as oxygen gas will have a higher temperature than hydrogen gas because it has fewer moles overall.

<h3>Briefing :</h3>

The mechanical behavior of ideal gases is described by the ideal gas law. It has the ability to compute the volume of gases created or absorbed.

This equation is frequently used in chemical equations to convert between volumes and molar quantities.

According to the ideal gas law, there is a relationship between gas pressure, temperature, and volume.

PV = nRT

V is the same for both

So,

T is same for both.

When n increases, T decreases, so since n for hydrogen gas is 1 and n for oxygen gas is 0.5, it follows that oxygen gas will have a higher temperature than hydrogen gas because it has fewer moles overall.
