Answer:

C-Its product is heavier than each of its reactants.

Explanation:

Correct equation:

¹⁴₇N + ¹₁H → ¹⁵₈O

In the reaction above, we can conclude within the given conditions of the reaction that the product formed is heavier than the reactants.

The product is oxygen with a mass number of 15 as shown by the superscript preceeding the symbol of the atom.

The reactants are:

Nitrogen, N with a mass number of 14

Hydrogen, H with a mass number of 1

The mass number is a true reflection of the mass of an atom. It clearly shows the mass of the nucleons which are the most massive particles that makes up an atom. The nucleons are protons and neutrons that makes up the tiny nucleus of the atom.

Oxygen here has more nucleons that each of Nitrogen and Hydrogen.

Determine the number of moles of O,(g) in the cylinder. The gram-formula mass of

FrozenT [24]

The number of mole of oxygen gas, O₂ in the cylinder given the data is 0.5 mole

<h3>Description of mole </h3>

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

<h3>How to determine the mole of O₂</h3>

From the question given, the following data were obtained:

Mass of O₂ = 16 g g
Molar mass of O₂ = 32 g/mol
Mole of O₂ =?

Mole = mass / molar mass

Mole of O₂ = 16 / 32

Mole of O₂ = 0.5 mole
