If our bodies are always giving off heat why dont you freeze to death?
Our bodies always give heat off but it doesn't freeze. Inside our boudies chemical reactions occurs , that's why we eat and breath, and such chemical reactions releases heat that compensates the lost heat.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Do all acid reactions give off heat?
No, endothermic reactions absorb heat. Exothermic gives off heat.
What is a chemical reaction producing heat and light?
Any chemical will give off light if it is heated to a sufficiently high temperature. There are also chemicals that give off light at relatively low temperatures. Fireflys produce a type of chemical called luciferins, that produce light.
What are Reactions such as fire burning give off energy in a form of heat called?
Those reactions are said to be exothermic.
What are considered Favorable chemical reactions?
Chemical reactions that occur spontaneously usually give off energy, usually heat.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Do most of the chemical reactions that give off light also produce heat?
Yes.
Can energy be asorbed or released during chemical reactions?
Yes they can be either absorbed or release during chemical reactions. That is why some reactions explode or give off heat and some absorb heat making them cooler.
If our bodies are always giving off heat why dont you freeze to death?

Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Are chemical reaction affected by differences in temperature?
Yes, temperature has an effect on the speed of the reaction. Also most chemical reactions create heat. I feel that it is not exactly correct to say that most chemical reaction create heat. That is true for exothermic reactions, which give off heat, but endothermic reactions absorb heat instead.
Do all acid reactions give off heat?
No, endothermic reactions absorb heat. Exothermic gives off heat.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat
Do all chemical reactions need heat to start them off?
no
