Answer:

7.5 g of hydrogen gas reacts with 50.0 g oxygen gas to form 57.5 g of water.

Explanation:

Here we have the check if the mass of the reactants is equal to the mass of the products.

Reactants

[tex]7.5+50=57.5\ \text{g}[/tex]

Products

[tex]57.5\ \text{g}[/tex]

The data is consistent with the law of conservation of matter.

Reactants

[tex]50+243=293\ \text{g}[/tex]

Products

[tex]206+97=303\ \text{g}[/tex]

The data is not consistent with the law of conservation of matter.

Reactant

[tex]17.7+34.7=52.4\ \text{g}[/tex]

Products

[tex]62.4\ \text{g}[/tex]

The data is not consistent with the law of conservation of matter.

Only the first data is consistent with the law of conservation of matter.
