Question

C12H22O11(s) + H2SO4(aq) + 1/2 O2(g) → _C(s) + CO2(g) + 12H2O(g) + SO2(g)

How many H atoms in 12H2O?
A) 12
B) 24
C) 36
D) 48

Answer 1

The number of hydrogen atoms in 12 water molecules (12H2O) is 24, which is found by multiplying the number of water molecules by the number of hydrogen atoms in each molecule.

Step-by-step explanation:

The question asks about the number of hydrogen atoms in a certain number of water molecules, which is a basic stoichiometry problem in chemistry.

In the given chemical equation, for every molecule of C12H22O11, 12 molecules of water (H2O) are produced. To find the total number of hydrogen atoms in 12H2O, we have to multiply the number of water molecules by the number of hydrogen atoms in each water molecule.

A single water molecule, H2O, contains 2 hydrogen atoms. Therefore, 12 molecules would have:

12 molecules x 2 hydrogen atoms/molecule = 24 hydrogen atoms.

Hence, the correct answer is B) 24.
