the total mass of the reactants equals the total mass of the products
Chemical reactions involve the breaking and forming of chemical bonds, resulting in the rearrangement of atoms to form new substances. The total mass of the substances before a chemical reaction is equal to the total mass of the substances after the reaction, as dictated by the law of conservation of mass.
No, chemical reactions can be endothermic or exothermic.
Yes, it's true.
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
These are not chemical reactions but thermonuclear reactions.
True. Some enzymes are able to catalyze multiple types of chemical reactions due to their flexible active sites that can accommodate different substrates. This versatility allows them to participate in various metabolic pathways within an organism.
Chemical bonds always break in chemical reactions, causing changes in energy.
No, chemical reactions can be endothermic or exothermic.
Chemical bonds always break in chemical reactions, causing changes in energy.
At equilibrium, the rates of the forward and reverse reactions are equal, but chemical reactions are still occurring.
yes. true.
always.
Yes, it's true.
no
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
True
True. Chemical reactions that absorb energy, also known as endothermic reactions, require an external source of energy to proceed. Without this added energy, the reaction will not occur.
