In a closed system, matter cannot enter or leave the system, but energy can still be exchanged with the surroundings. Chemical reactions in a closed system will reach equilibrium, where the rates of the forward and reverse reactions are equal and the concentrations of reactants and products remain constant. The total amount of matter in the system will not change during a reaction in a closed system.

Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is it true that lowering the temperature slows down most chemical reactions?
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
When the stabilized state of an equilibrium system is altered further chemical reactions begin until a new equilibrium is reached?
Yes, once the equilibrium of a system is disturbed, the system will react to establish a new equilibrium. This involves shifts in the forward and reverse reactions to minimize the disturbance and reach a stable state again.
Do One enzymes can be used for many different types of chemical reactions is this true or false?
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.
What are all the chemical reactions in the body combined?
Together the chemical reactions are called as biological oxidation. There are some reactions of reduction and some reactions are of oxidation. But the sum total of the reaction is oxidation. This is true for the animal kingdom as a whole. The reverse is true for the plant kingdom. There are some reactions of reduction and some reactions are of oxidation.There the biological reduction dominates. The sum total is biological reduction. Plants synthesize the food and animals use the food for various metabolic activities.
What is true about matter during a chemical reaction the mass of the reactions is not related to the mass of the prroduct?
No. In a closed system, the mass of the products should equal the mass of the reactants.
Chemical reactions that occur in cells are called biochemical reactions?
yes. true.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is Electrons in an excited state are more likely to enter into chemical reactions true?
True
Chemical reactions that absorb energy will not occur without a source of energy true or false?
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.
Electrolytes determine most of the chemical and physical reactions of the body?
True
Minimum gibbs free energy is NOT attained by a semipermeable membrane. True or false?
True. The minimum Gibbs free energy is not attained by a semipermeable membrane, as the membrane itself does not participate in any chemical reactions that could lower the system's overall free energy. The minimum free energy is achieved through chemical reactions occurring within the system.
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
Is this true about balanced chemical equations that they provide the molar ratios of reactants and products in chemical reactions?
Yes.
Is it true that lowering the temperature slows down most chemical reactions?
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
Are antibodies proteins that catalyze chemical reactions without being physically altered?
No, antibodies are not proteins that catalyze chemical reactions without being physically altered. Antibodies are proteins produced by the immune system to help recognize and neutralize foreign substances, such as bacteria and viruses. Enzymes are proteins that catalyze chemical reactions without being physically altered.
Are electrons more likely to enter chemical reactions in an excited state?
True.
