12. assess is the following equation balanced? if not, correct the coefficient
balance the equation.
2k, cro (aq) + pb(no3)2(aq) + 2kno3(aq) + pbcroa(s)

The given equation is incorrect.

Explanation:

Chemical equation:

2KCrO₄ + Pb(NO₃)₂ → 2KNO₃ + PbCr₄

This is incorrect.

Correct chemical equation:

K₂CrO₄ + Pb(NO₃)₂ → KNO₃ + PbCrO₄

Correct balanced chemical equation:

K₂CrO₄ + Pb(NO₃)₂ → 2KNO₃ + PbCrO₄

This is correct chemical equation. There are two potassium atom one chromium atoms,  ten oxygen atom, two nitrogen atom and one lead atom are present on both side of equation. So this equation is correctly balanced. while given equation is incorrect.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
