Question

According to the law of conservation of mass, if two atoms of hydrogen are used as a reactant, how many atoms of hydrogen must be part of the product?

Answer 1

Answer:

2 atoms

Explanations:

According to the law of conservation of mass, for any closed system involving the transfer of energy and matter, the mass of the system must remain constant over time.

If two atoms of hydrogen are used as a reactant, the number of hydrogen atoms of product generated is as shown in the chemical reaction below;

$\begin{gathered} H_2+H_2\rightarrow2H_2 \\ \end{gathered}$

From the given reaction, we can see that when the two atoms of hydrogen reacted, 2 atoms of hydrogen is also formed showing that the mass of the system is constant.

In conclusion, if two atoms of hydrogen are used as a reactant, TWO atoms of hydrogen must be part of the product
