Which of the following correctly describes the law of conservation of matter? Group of answer choices

Matter can only be created, but not destroyed in chemical equations

Matter can neither be created nor destroyed during a chemical reaction

Matter can be destroyed during a chemical reaction as long as it is created again in a different reaction

Matter makes up 98% of stuff in the universe, so it has to be created and destroyed sometimes

Which change will decrease the number of effective collisions during a chemical reaction? a. adding a catalyst b. increasing the surface area c. decreasing the temperature d. increasing the reactant concentrations e. increasing the volume of the reactants

Which of the following characteristics are true of enzymes? check all that apply. a.)the structure of an enzyme can change if conditions change. b.)a single enzyme can normally catalyze a wide variety of reactions under many conditions. c.)enzymes are found only in nonliving systems. d.)enzymes allow living things to regulate body conditions through feedback mechanisms. e.)enzymes bind to specific substrates in specific ways. f.)enzymes increase the rate of reaction. g.)when shown in energy-reaction diagrams, enzymes represent the higher activation energy.
