What is the molecular ratio in the following equation:H2O + SO3 = H2SO4
1:1:1
1 molecule H2O to 1 molecule SO3 to 1 molecule H2SO4.
To determine the molecular ratio in the given equation H2O + SO3 = H2SO4, we need to examine the coefficients in front of each compound.
The coefficient in front of H2O is 1, meaning there is 1 molecule of water. The coefficient in front of SO3 is also 1, indicating that there is 1 molecule of sulfur trioxide. The coefficient in front of H2SO4 is 1 as well, meaning there is 1 molecule of sulfuric acid.
Therefore, the molecular ratio in the equation is:
1 H2O : 1 SO3 : 1 H2SO4
This ratio implies that for every molecule of water and sulfur trioxide that react, 1 molecule of sulfuric acid is produced.
