Respuesta :
There are 6 hydrogens and 2 nitrogen when 3h2 reacts with N2 such that the equation follows the law of conservation of mass.
It is already balanced when N2(g) + 3H2(g) 2NH3(g). There are two nitrogens on the left and two on the right, as you can see. On the left, there are 6 hydrogens, and on the right, there are 6.
The law of conservation of mass, also known as the principle of mass conservation, in physics and chemistry states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time because the mass of the system cannot change and therefore quantity cannot be added to or subtracted.
According to the rule of conservation of mass, mass is neither generated nor destroyed during a chemical process. For instance, when coal is burned, the carbon atom in it transforms into carbon dioxide.
