What else can I help you with?
Substances that promote chemical reactions in living things but not affected by the reaction are?
enzymes. Enzymes are biological catalysts that increase the rate of chemical reactions in living organisms without being consumed in the process. They help lower the activation energy required for a reaction to occur.
How does the relationship between pH and temperature affect chemical reactions in a solution?
The relationship between pH and temperature can affect chemical reactions in a solution by influencing the rate and efficiency of the reactions. Changes in pH can alter the ionization of molecules, which can impact the reactivity of the substances involved. Additionally, temperature can affect the kinetic energy of molecules, leading to changes in reaction rates. Overall, variations in pH and temperature can either promote or inhibit chemical reactions in a solution.
What is an oxidizing substance?
An oxidizing substance is a chemical that has the ability to accept electrons from other substances, causing them to become oxidized. This process typically involves the transfer of oxygen atoms or other electronegative atoms to the substance being oxidized. Oxidizing substances are often used to initiate or promote chemical reactions that involve the loss of electrons.
Reusable complex proteins that promote chemical reactions within cells are called?
Catalyst
What is chemical weathering name three examples what climate is it likely to occur in?
Chemical weathering is the breakdown of rocks through chemical reactions. Examples include dissolution, oxidation, and hydrolysis. It is likely to occur in humid climates with warm temperatures and abundant rainfall, as these conditions promote faster chemical reactions.
What is the role of sulphuric acid in the reaction?
Sulfuric acid can act as a catalyst in some reactions by providing protons that can initiate chemical transformations. It can also function as a dehydrating agent, removing water molecules from reactants to promote certain reactions. Additionally, sulfuric acid can serve as a source of sulfate ions in reactions where sulfate compounds are needed.
Is enzymes protiene?
Enzymatic proteins are proteins, or enzymes, that speed up chemical reactions in the body. These reactions break apart biological molecules without being changed themselves.
What type of climate will be most prone to chemical weathering?
A warm and humid climate is most prone to chemical weathering. High temperatures and moisture promote chemical reactions that break down rocks and minerals over time.
How can water play a role in chemical weathering?
Water can accelerate chemical weathering by dissolving minerals in rocks, breaking them down into smaller particles. Water can also facilitate chemical reactions between minerals and substances in the environment, leading to the decomposition of rocks into different minerals. Additionally, water can promote the growth of certain organisms like lichens, which produce acids that further aid in the breakdown of rocks.
When is chemical weathering most active?
Chemical weathering is most active in warm and humid climates with abundant rainfall. This is because the presence of water and warm temperatures facilitate reactions that break down rocks and minerals. High temperatures and increased moisture content promote the chemical reactions that lead to weathering.
How can we create a reducing atmosphere in the laboratory to facilitate certain chemical reactions?
To create a reducing atmosphere in the laboratory for specific chemical reactions, one can use gases like hydrogen or carbon monoxide to displace oxygen. This helps to prevent oxidation and promote reduction reactions. Additionally, using a reducing agent such as sodium borohydride can also help create a reducing environment.
What substances promote tooth decay?
