Question

explain in details giving examples how to balance a chemical equation

Answer 1

Here is an example to show u how to balance an equation;-
Fe + H2O –> Fe3O4 + H2
Here we will start balance with that element which has the highest difference. Let's start with O
LHS. RHS
1. 4
Fe + 4H2O –> Fe3O4 + H2

Now we have balanced oxygen, but now H2 becomes unbalanced
LHS. RHS
8. 2
Fe + 4H2O –> Fe3O4 + 4H2
Now we have balanced H2 but Fe is yet to be done
LHS. RHS
1. 3
3Fe + 4H2O –> Fe3O4 + 4 H2O
Now this is our final balanced equation where ;
LHS. RHS
Fe. 3. 3
O. 4. 4
H2. 8. 8

Now, it's balanced...


Hope it helps ......

Answer 2

Answer:

A chemical equation shows the chemical formulas of substances that are reacting and the substances that are produced. The number of atoms of the reactants and products need to be balanced. In this lesson, we will discuss balancing chemical equations.

Let's take a look at this scale. We can see that it is unbalanced, with the right (red) side, weighing more than the left (blue) side. In order for the two sides to be balanced, we need to put a little more mass on the left side until they are the same mass.

Just like we want the scale to be balanced on both sides, a chemical equation should also be balanced on both sides. A chemical equation shows us the substances involved in a chemical reaction - the substances that react (reactants) and the substances that are produced (products).
