Automobile airbags inflate due to the formation of nitrogen gas from the chemical reaction 2nan3(s)⟶3n2(g)+2na(s) identify the number of each atom in the reactants and products for this balanced reaction. identify the number of na atoms in the reactants and products.

The Left and right hand side of a chemical equation denotes the reactant and product side respectively. Hence, the number of Na atoms in the reactant and product side is 2 atoms respectively.

Given the equation :

Product side :

Na atoms = 2 atoms

Nitrogen atoms = 2 × 3 = 6 atoms

Reactant side :

Na = 2 atoms

Nitrogen, N atoms = (3 × 2) = 6 atoms

Therefore, the Number of Na atoms in the reactant and product side is 2 atoms.

First part:

2 atoms of Na

6 atoms of N

Second part:

2 atoms of N

2 atoms of Na

Why?

We are given the chemical reaction, so, we can extract the number of atoms for both reactants and products.

We are given the chemical equation:

We can rewrite it as follow:

From the reactants, we have:

From the products we have:

Hence, we have that:

There are 6 atoms of N in the reactants and 6 atoms of N in the products.

and

There are 2 atoms of Na in the reactants and 2 atoms of Na in the products since we have a balanced equation.

Have a nice day!

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,

will have a gram-molecular weight of 352g.
