What else can I help you with?
Is the reaction of hydrogen are exothermic or endothermic?
A hydrogen reaction is a release of energy, therefore is defined as exothermic.
What is base reaction?
Acid + Base = Salt +Water
What is the rapid reaction of any substance with oxygen?
Oxidation is the rapid reaction of any substance with oxygen. This process often results in the formation of new compounds and release of energy in the form of heat and light.
What is the burning substance of a substance?
The burning substance of a substance refers to the part of the substance that undergoes combustion or oxidation when exposed to heat or a flame. This process typically involves the release of heat, light, and often the production of new chemical compounds as the substance reacts with oxygen in the air.
What is it called when a substance burns in oxygen?
When a substance burns in oxygen, it is called combustion. It is a chemical reaction that produces heat and light, usually accompanied by the release of carbon dioxide and water vapor.

What name do you give to a substance to release energy?
A substance to release energy is usually called a fuel. A chemical reaction that releases energy is called exothermic.

Is a chain reaction possible in a substance that emit no neutrons when it fission?
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
Is a substance that causes the release of antibodies that often produce an allergic reaction?
No, an allergic reaction is typically caused by a release of histamines from the eosinophils. Antibodies are produced by lymphocytes in response to a bacterial infection.
What energy transformation in iron?
When iron rusts, a chemical reaction occurs where oxygen in the air combines with the iron. This reaction results in a release of heat energy, which is a transformation from chemical energy (stored in the iron) to thermal energy (heat).
How does activation energy determine if a reaction will release or absorb energy?
Activation energy is the energy required to start a chemical reaction. If the activation energy is higher than the energy released by the reaction, the reaction will absorb energy and be endothermic. If the activation energy is lower than the energy released by the reaction, the reaction will release energy and be exothermic.
What is it called when a substance burns in oxygen?
When a substance burns in oxygen, it is called combustion. It is a chemical reaction that produces heat and light, usually accompanied by the release of carbon dioxide and water vapor.
What observations will you look for to determine if a metal undergoes a reaction?
To determine if a metal undergoes a reaction, you can look for changes in appearance, such as color or texture, the release of gas or heat, and the formation of a new substance.
How can you determine if a chemical reaction is a redox reaction?
A redox reaction can be determined by looking for changes in the oxidation states of the elements involved. If there is a transfer of electrons from one substance to another, it is likely a redox reaction. Additionally, the presence of a change in color, formation of a gas, or release of heat can also indicate a redox reaction.
