Question

7 H2SO4 what is the coefficient? what are the subscript numbers?

Answer 1

Answer:

Coefficient: number balancing sulfuric acid in a chemical reaction.

Subscripts: number of atoms of each element forming the compound.

Explanation:

Hello!

In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:

- Two hydrogen atoms.

- One sulfur atom.

- Four oxygen atoms.

We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.

Moreover, since the molecules is given as 7 H2SO4 ; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.

Best regards!
