Question 10

There are 4 hydrogen atoms present in the reactants.

In the context of the reactants being analyzed, a total of four hydrogen atoms can be identified as part of the molecular structure of the substances involved in the reaction.

A) 2

This option is incorrect because it underestimates the number of hydrogen atoms present. A thorough examination of the reactants reveals that there are actually more hydrogen atoms than just two.

B) 4

This option is correct as it accurately reflects the total number of hydrogen atoms found in the reactants. A detailed analysis of the molecular formulas shows that the sum of hydrogen atoms equals four.

C) 1

This option is incorrect since it suggests that only one hydrogen atom is present. The molecular formulas of the reactants indicate that this is not the case, as multiple hydrogen atoms are clearly involved.

D) None of the above

This option is also incorrect because it implies that the number of hydrogen atoms is either not quantifiable or does not match any of the provided options. However, we have established that there are indeed four hydrogen atoms.

Conclusion

In conclusion, the correct answer is B, as it precisely represents the total count of hydrogen atoms in the reactants. The other options fail to accurately reflect this count, highlighting the importance of careful analysis of molecular structures in chemical equations.
