Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
What do chemical reactions in living organisms need to start?
all they need is energy
Do chemical reactions give out energy in the form of heat light or sound?
all 3
Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
Dose a chemical reaction create molecules and compounds?
Yes, it is true: all chemical reactions create new molecules of compounds.
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.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
FalseAll chemical reactions require an initial input of energy called activation energy.
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
What are some things that need chemical energy?
Candle and all Chemical reactions
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
Why is burning of gas considered a chemical change?
All burning reactions involve chemical reactions (chemical changes).
Which of the following is true for all exergonic reactions?
the reactants have more total energy than the products.
What are some things that need energy?
Candle and all Chemical reactions
What energy is associated with chemical reactions?
not exactly sure what you mean but all i know is that its chemical potential energy -> light heat or electrical energy
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
What do chemical reactions in living organisms need to start?
all they need is energy
