The net ionic equation: Fe(s) + Pb2+ (aq) – Fe2+ (aq) + Pb(s) illustrates conservation of 1.
mass and charge
2.
charge but not mass
3.
mass but not charge
4.
neither mass nor charge

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.

The diagram below shows the movement of particles. what does this piece of evidence best support? the collision theory the maxwell-boltzmann distribution the effect of pressure on reaction rates the effect of temperature on reaction rates

What if it is did darwin used to support his theory of evolution
