WebAn arrow represents the direction of the reaction and is read as “yields” or “produces.” Chemical reactions can be classified by considering the number of reactants and products in the reaction, the physical or chemical nature of the reactants and products, and the how the atoms are rearranged during the reaction. WebA chemical equation is balanced when the number of atoms is the same on both sides. To balance chemical equations, there are some steps we need to follow. As an example, take a look at the chemical equation below: K + H 2 O → KOH + H 2. Step 1: Count the number of atoms present on each side of the chemical equation.

WebFirst things first: we need to balance the equation! In this case, we have 1 1 \ce {Na} Na atom and 3 3 \ce {H} H atoms on the reactant side and 2 2 \ce {Na} Na atoms and 2 2 \ce {H} H atoms on the product side. We can balance the equation by placing a 2 2 in front of \ce {NaOH} NaOH (so that there are 2 2 \text {Na} Na atoms on each side) and ... WebThere's 2 on the left and 1 on the right, so we need to change the coefficient of NH3 to 2. Now we have. N2 + H2 -> 2NH3. Total the atoms up again: On the left there is 2 N and 2 H still. On the right there is 2 N and 6 H now. So now all we need to do is make the left side have 6 H in total.
