Question

true or false: a synthesis reaction involves breaking down a compound into simpler substances.
true
false
if you start a chemical reaction with 4 grams of reactant a and 6 grams of reactant b, according to the law of conservation of mass, what will be the total mass of the product(s)?
10 grams
24 grams
2 grams
cannot be determined
classify the following balanced chemical equation: 2so₂ + o₂ → 2so₃
decomposition
synthesis
single replacement
combustion

Explanation:

Step1: Recall synthesis reaction definition

A synthesis reaction combines simpler substances to form a more complex one, not break down. So the first statement is false.

Step2: Apply law of conservation of mass

The law states mass is conserved in a chemical reaction. Mass of reactants = 4 g (A)+ 6 g (B)=10 g. So mass of products is 10 g.

Step3: Analyze reaction type

In the equation \(2SO_{2}+O_{2}
ightarrow2SO_{3}\), two substances combine to form one, which is a synthesis reaction.

Answer:

False
10 grams
Synthesis
