A is Ea, which stands for activating energy. Energy is needed to get the reaction underway and Ea is the energy needed to “start” the reaction.
B is the temperature either released or absorbed.
The diagram shows that the reaction is exothermic based on the fact that the products energy is lower than the reactants. That is because energy (which is temperature in this case) is released during the process. If the reactants would have been lower than the products, the reaction would be endothermic.
This is true. Solid, Liquid, and Gas.
Hope that helps!!
You can simply subtract the atomic number from the mass number in order to find the number of neutrons.
sorry but if you are looking for an answer I don't know one. :(
the answer is Te because O is oxygen.
