What else can I help you with?
What effects do catalysts have on chemical rections?
Catalysts generally speed up chemical reactions.
What is the energy role of chloroplasts?
They are energy transformers. They convert light energy to chemical energy
Does the rate of chemical reactions slow as the temperature rises?
No. The speed of all chemical rections increases when temperature rises.
An element that speeds up chemical rections is called?
Stimulants - but more probably catalyst.
Can chemical reactions absorb energy?
Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.
Do trees absorb light?
Yes, they do absorb light. They transfer the light-energy to chemical energy by a proces called fotosynthesis.
Are chemical reactions that absorb energy will occur without a source of energy?
false
What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
Is it true that Every chemical reaction gives off energy?
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
Does a chemical reactions that absorb energy will not occur without a source of energy?
Yes, it is true.
Which type of chemical reaction needs to absorb energy to proceed?
endothermic
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
