Which statement best describes the energy of activation? a. it is not affected by a catalyst b. it is lower if the reaction temperature decreases c. it is higher if the reaction temperature increases d. it is more quickly overcome when the temperature increases

Explain why scientists use shared characteristics to make cladograms.

What will most likely happen when two bromine atoms bond together?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
