matter cannot be created or destroyed

true
false

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

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.

True. According to the principle of conservation of mass and energy, matter cannot be created or destroyed, but can only change forms or be transferred between objects or systems. This principle is a fundamental concept in physics and chemistry.

True. The concept that matter cannot be created or destroyed is known as the law of conservation of mass, which is a fundamental principle in physics and chemistry. According to this law, the total amount of matter in a closed system remains constant over time. While matter can change form, such as from solid to liquid to gas, the total amount of matter remains unchanged. This principle is derived from a combination of experimental observations and the conservation of mass-energy relationship in physical systems.
