Question

Use the equation to answer the question. 21H+ 21H→ 42H+energy Which statement best describes the mass numbers of the atoms in the reaction? (1 point) Responses There are two atoms with mass numbers of 2. There are two atoms with mass numbers of 2. There are two atoms with mass numbers of 1. There are two atoms with mass numbers of 1. There is one atom with a mass number of 2. There is one atom with a mass number of 2. There is one atom with a mass number of 1.

Answer 1

There are two atoms with mass numbers of 1.

Answer 2

Based on the equation, 21H + 21H → 42H + energy, the statement that best describes the mass numbers of the atoms in the reaction is:

There is one atom with a mass number of 2.

Answer 3

To answer the question, we need to analyze the equation provided: 21H + 21H -> 42H + energy

In this equation, "21H" represents two hydrogen (H) atoms with a mass number of 21 each. Since there are two "21H" in the reactant side, we can say that there are two atoms with a mass number of 21.

Similarly, in the product side, "42H" represents one hydrogen atom (H) with a mass number of 42. Hence, there is one atom with a mass number of 42.

Therefore, based on the equation, the correct answer would be: "There are two atoms with mass numbers of 21 and one atom with a mass number of 42."
