Which statement best represents the law of conservation of Mass
Matter can disappear in a chemical reaction
The total mass of substances stays the same a chemical reaction
The math of a substance increases hero physical change
Math conservation only applies to gases
The total mass of substances stays the same in a chemical reaction.
What do elements in the same column on the periodic table having common
Elements in the same column on the periodic table have common chemical properties.
The statement that best represents the law of conservation of mass is:
"The total mass of substances stays the same in a chemical reaction."
To understand why this statement is correct, we need to review the law of conservation of mass. This law states that mass is neither created nor destroyed in a chemical reaction. The total mass of the reactants should equal the total mass of the products.
To determine the answer to this question, we can examine the other statements and eliminate them as incorrect:
- "Matter can disappear in a chemical reaction": This statement is incorrect because the law of conservation of mass tells us that matter cannot disappear. It can undergo changes, but the total mass remains the same.
- "The mass of a substance increases during a physical change": This statement is incorrect because the law of conservation of mass only applies to chemical reactions, not physical changes. In a physical change, the substance may change its state or appearance, but the total mass remains constant.
- "Mass conservation only applies to gases": This statement is incorrect because the law of conservation of mass applies to all states of matter (solid, liquid, gas). It is not limited to gases.
By process of elimination, we can conclude that the statement "The total mass of substances stays the same in a chemical reaction" best represents the law of conservation of mass.
