When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
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 always make new substances?
No all chemical reactions do not make new things because if you do a chemical reactions using two of the same things e.g carbon dioxide + carbon dioxide you are not making anything else so no not all chemical reacions make new things
Are gases always soluble in each other?
Generally gases are miscible in each other; sometimes chemical reactions occur.
What is always true of chemical reactions?
the total mass of the reactants equals the total mass of the products
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
Why do chemical reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
What changes are always involved in chemical reactions?
electrons are always involved in chemical reactions. how they are positioned which atom they are located if they are sharing paired unpaired etc.
Do Chemical reactions involve the interplay of the electrons of the reacting chemical?
always.
Do chemical reactions always involve changes in energy?
no
What type of reactions always release energy?
exothermic reactions
Chemical reactions always involve changes in a chemical?
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Why are combustion reactions considered exceptions to the rules of chemical reactions?
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
Is energy always involved in making or breaking chemical bonds?
no, some reactions are spontenous.
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.
