To balance the equation 4H2 + 2C, we need to adjust the number of atoms on each side of the equation. Adding a coefficient of 2 in front of C on the left side will balance the carbon atoms. The balanced equation will be 4H2 + 2C2.
O2 +4H2--> 2H2O
It is an exponent and means that the number is to be raised by that power as foe example 43 means 4*4*4 = 64
2Ag20 --> 4Ag + 02 Fe304 + 4H2 --> 4H20 + CuCl2
4H2 + N2 --> 2H4N+
I'm sure you can figure out this word problem. It means what is 4 X 3 = ?
