Science Revision Reactions. Flashcards
what are reactants?
they are on the right side of the arrow. They react together to form the products.
what are the products?
they are on the right side of the arrow.
what does conserved mean?
that the total amount of reactants will be equal to the mass of the products.
what is combustion?
the burning of fuel in oxygen.
what does exothermic mean?
means energy being released.
give an example of exothermic reaction?
water freezing and turning into ice.
what does endothermic mean?
means energy being taken in.
give an example of endothermic reaction.
ice melting and turning into water.
what do energy diagrams show?
the values of energy between the reactants and the products.
what happens in the exothermic energy level diagrams?
the reactants go on top and the products go on the bottom.
do bonds form or break in endothermic reactants?
they break them.
