Explanation:
N₂ + 3H₂ →2 NH₃
would be the correct equation as both hydrogen and nitrogen gas present in diatomic form thus the reactant would be N2 and H2. The charges of every atom of hydrogen and -3 and hydrogen hav one positive so the coefficent would be 3 for making bonds in the equation.
Explanation:
1=2 atoms
2=4-n where n is the number of bonds to that carbon
3=10
4=2
Substance A is chlorophyll and Substance B is oxygen
