C3F ~ Energy

?
What is an exothermic reaction?
Reaction that gives out energy to surroundings usually in form of heat (shown by rise in temperature).
1 of 5
What is an endothermic reaction?
Reactions That take in energy from surroundings usually in the form of heat (shown by fall in temperature).
2 of 5
What is the reaction to show whether it is an exothermic reaction or endothermic on?
Measure the temperature of individual reactants and then mix them and measure the temp of the mixture.
3 of 5
Do bonds break or are bonds formed in exothermic reactions?
form. Energy released when bonds form.
4 of 5
What is the equation for relating energy to SHC?
E= M x C x 'O' ( e- energy (J), M= mass (KG), 'O' = temp change in degrees C)
