Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
Chemical reactions that energy often occur spontaneously?
endothermic: or energy absorbing reactions
What are considered Favorable chemical reactions?
Chemical reactions that occur spontaneously usually give off energy, usually heat.

What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
Are chemical reactions that absorb energy will occur without a source of energy?
false
Does a chemical reactions that absorb energy will not occur without a source of energy?
Yes, it is true.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..

What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Chemical reactions that energy often occur spontaneously?
endothermic: or energy absorbing reactions
Does energy transformation occur in chemical reactions?
False
