the mass to change ratio of the proton is found to be 1.044×10¯⁸KG/C. the change on the proton is 1.602×10¯¹⁹C. calculate the mass of proton.

1.54 x 10⁻¹¹kg

Explanation:

The charge to mass ratio is given as:

               1.044 x 10⁻⁸kg/C

 Charge on the proton  = 1.602 x 10⁻¹⁹C

 So;

      is the charge to mass ration

e is the charge

m is the mass

  1.044 x 10⁻⁸kg/C  =    

    m =   = 1.54 x 10⁻¹¹kg

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
