Question

what elements are in NaC2HO4 and how many atoms are in each element​

Answer 1

Answer:

Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.

                 A + B ⟶ Product

Particles: 6      8              6

If six A atoms form six product molecules, each molecule can contain only one A atom.

The formula of the product is ABₙ.

If n = 1, we need six atoms of B.

If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.

Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.

Answer 2

There are are four elements in the compound. One atom of sodium, two atoms of carbon, one atom of hydrogen and four atoms of oxygen making a total of eight atoms.

A compound is composed of elements. The elements that constitute a compound have atoms.

The compound NaC2HO4 is composed of one sodium atom, two carbon atoms, one hydrogen atom and four oxygen atoms. This is easily deducible from the molecular formula of the compound.

The molecular formula shows us the number of atoms of each element in the compound.
