Solution

Solution Steps

Step 1: Understanding the Balanced Chemical Equation

In a balanced chemical equation, the number of each type of atom on both sides of the equation must be equal. This is due to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.

Final Answer for Question 14

$\boxed{\text{B) the same}}$

Step 2: Classifying the Reaction

The given reaction is: \[ \mathrm{SO}_{3}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{H}_{2} \mathrm{SO}_{4} \] This reaction involves the combination of sulfur trioxide ($\mathrm{SO}_3$) and water ($\mathrm{H}_2\mathrm{O}$) to form sulfuric acid ($\mathrm{H}_2\mathrm{SO}_4$). This type of reaction is known as a combination reaction.

Final Answer for Question 15

$\boxed{\text{B) combination}}$

Step 3: Identifying the Reaction Type

In a single replacement reaction, one element (metal or halogen) replaces another element in a compound to form a new compound.

Final Answer for Question 16

$\boxed{\text{D) single replacement}}$
