When sodium phosphate reacts with sulfuric acid, forming sodium sulfate and phosphoric acid, the stoichiometric coefficient for sulfuric acid in the balanced chemical equation is 3.
In every balanced chemical equation, the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side. The stoichiometric coefficient is the number written in front of each reactants and products that tells how many moles of each are needed in the reaction.
The chemical equation for the given reaction is:
+
=
+ 
Put the necessary stoichiometric coefficient to balance each element.
Balancing Na:

Notice that H and O are already balanced.
Hence, the balanced chemical equation for the reaction is:
+
=
+ 
where 3 is the stoichiometric coefficient of sulfuric acid,

The answer is B, the electrolysis of water. One cannot be the answer since the condensation of steam requires a loss of heat, an exothermic reaction. Numbers 2 and 3 cannot be correct either as they do not indicate energy in the chemical equation, and so it must be balanced throughout. Meaning that the only possible answer is B.
A, It encourages scientists to give convincing evidence for ther results.
A) I-
An anion is is a negatively charged ion. :)
The question ask on which of the following is the best representation of adhesion, cohesion and surface tension of water and the answer among the choices is letter C. Water droplets forming a bead like shape over a glass table. I hope you are satisfied with my answer.
