True. The law of conservation of matter states that matter cannot be created or destroyed, only transformed or rearranged.
A student is performing a chemical reaction. the mass of Reactant 1 is 33 grams. The mass of Reactant 2 is 57 grams. The reaction produces a solid and a gas. The mass of the solid is 26 grams. What is the mass of the gas?
116 grams
26 grams
64 grams
90 grams
116 grams
26 grams
64 grams
90 grams
To find the mass of the gas produced, we need to subtract the mass of the solid produced from the total mass of Reactant 1 and Reactant 2.
Total mass of Reactant 1 and Reactant 2 = 33 grams + 57 grams = 90 grams.
Mass of the gas produced = Total mass - Mass of the solid produced = 90 grams - 26 grams = 64 grams.
Therefore, the mass of the gas produced is 64 grams.
Total mass of Reactant 1 and Reactant 2 = 33 grams + 57 grams = 90 grams.
Mass of the gas produced = Total mass - Mass of the solid produced = 90 grams - 26 grams = 64 grams.
Therefore, the mass of the gas produced is 64 grams.
