What else can I help you with?
What element is needed in both corrosion and combustion?
Oxygen is the essential element required for both corrosion and combustion. In corrosion, it reacts with metals, leading to their degradation, while in combustion, it supports the chemical reaction that produces heat and light when fuels burn. Both processes involve oxidation reactions, highlighting the critical role of oxygen in various chemical transformations.
What chemical is absolutely needed for chemical reactions to happen in a cell?
These chemicals are called enzymes.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
Which fuels release chemical energy?
Fuels such as gasoline, diesel, natural gas, and coal release chemical energy when they undergo combustion reactions. This chemical energy is then converted into heat or mechanical energy to perform work.
What facilitates chemical reactions by reducing the energy needed for it to occur?
A catalyst

Why isn't water flammable?
Water is not flammable because it does not contain any substances that can undergo combustion. Its molecular structure does not support the chemical reactions needed for burning.
Why is oxygen necessary for so many chemical reactions?
Oxygen is not a special element 'needed' in so many reactions, though it is:quite commonquite reactivebut carbon and hydrogen are probaly more common in more reactions than oxygen is.
What chemical is absolutely needed for chemical reactions to happen in a cell?
These chemicals are called enzymes.
Why is chemical energy needed in all chemical reactions?

What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
Which fuels release chemical energy?
Fuels such as gasoline, diesel, natural gas, and coal release chemical energy when they undergo combustion reactions. This chemical energy is then converted into heat or mechanical energy to perform work.
Why are enzymes needed to control chemical reactions in cells?
it acts as a catalyst
What is needed for all chemical reactions in a cell?
ENZYMES! its in my text book.
What facilitates chemical reactions by reducing the energy needed for it to occur?
A catalyst
Is driving a car a chemical or physical reaction?
Driving a car involves both chemical and physical reactions. The combustion of fuel in the engine is a chemical reaction that produces the energy needed to move the car, while the physical interactions between the tires and the road surface enable the car to accelerate, brake, and turn.
What type of protein speeds chemical reactions?
Enzymes are proteins that speed up chemical reactions in the body by lowering the activation energy needed for the reaction to occur.
