Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()Na2

Answer:

The coefficients in order are 2, 1, 1

Explanation:

Each side of the reaction needs to have the same number of each element due to conservation of matter.

First I looked at what was uneven, notice there are 2 Na on the left side and 4 Na on the left. The easiest way to fix that is to add a 2 on the Na2HPO4:

2(Na2HPO4)--> Na4P2O7 + H2O

Next take count of each element on both sides to see if the 2 balanced everything:

On the left there are 4 Na, 2 H, 2 P, and 8 O

On the right there are 4 Na, 2 H, 2 P, and 8 O

Since both sides match, you are done!

HELP!!!!

Answer: Option (b) is the correct answer.

Explanation:

Since energy of reactants is less than the energy of products. Therefore, it means energy is absorbed during the reaction.

As the energy required to break the bonds in the reactants is greater than the energy released when products are formed.

Therefore, it is an endothermic reaction.

Thus, we can conclude that the statement, it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed is correct.
