What else can I help you with?
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.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
Are compounds reversible?
Compounds can undergo reversible reactions where they can be converted back to their original form. This often depends on the conditions of the reaction, such as temperature and pressure. However, not all compounds exhibit reversible behavior.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
Chemical reactions drive all of the activities within what?
Chemical reactions drive all of the activities within living cells.
What chemical reactions are reversible?
All physical changes are reversible.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
When elements form compounds can the elements not be recovered?
some but not all......many reactions are reversible and many r irreversible....depends on chemistry of reactions, physical change or chemical change...
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.
Are chemical changes reversible?
I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
Is all physical reactions are reversible?
No, not all physical reactions are reversible. Some physical reactions are irreversible, meaning they cannot easily be undone or reversed to their original state. Examples of irreversible physical reactions include burning a match or breaking a glass.
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.
Can all chemical reactions in the body move back and forth?
No, not all chemical reactions in the body can move back and forth. Some reactions, such as irreversible reactions like the breakdown of glucose for energy, only proceed in one direction. However, reversible reactions, like the binding and release of oxygen to hemoglobin, can move in both directions depending on the conditions in the body.
Are all chemical reactions reversible?
Some chemical changes are easily reversible, though most are not. An example of a reversible chemical reaction is as follows: H2O + CO2 <-> H2CO3 When carbon dioxide is run into water under pressure, they react to form carbonic acid (seltzer water), when the pressure is released, the carbon dioxide dissociates with the water and bubbles off into the atmosphere (the seltzer water goes flat). The following reaction is irreversible: CH4 + 3O2 -> CO2 + 2H2O
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
Atoms can disappear completely in some chemical reactions-true or false?
false. atoms can either be fused or defused in all chemical reaction.
What do chemical reactions have to do with life?
chemical reactions are going on in our bodies all of the time
