Question

The complete combustion of methane can be seen in the equation: CH4 + 2 points

202 - CO2 + 2H2O If 50 g of methane are reacted completely, which
statement describes the reaction? *
O The total mass of the reactants is 50 g.
O The total mass of products is 50 g.
O The total mass of products is less than 50 g.
The total mass of reactants is greater than 50 g.

Answer 1

Answer: The statement total mass of reactants is greater than 50 g is true.

Step-by-step explanation:

According to law of conservation of mass, it is known that mass can neither be created nor it can be destroyed but it can only be transformed from one form to another.

For example,
`CH_(4) + 2O_(2) \rightarrow CO_(2) + 2H_(2)O`

Here, mass of methane is 50 grams but oxygen is also present over here whose mass isn't given. This means that total mass of reactants is greater than 50 grams.

Thus, we can conclude that the statement total mass of reactants is greater than 50 g is true.
