A 5,700kg truck hit a 906kg car at an intersection. They were both traveling 50km/h. What was the momentum of the truck before it hits the car?

Based on the equation and the information in the table, what is the enthalpy of the reaction?

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.
