Answer 2

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the same number of each type of atom is present on both sides of the equation. Let's balance the given chemical equations:

1) Li2S + FeCl3 -> To balance this equation, we start by counting the number of atoms of each element on both sides of the equation. There are 2 lithium (Li) atoms on the left and 1 on the right, 1 sulfur (S) atom on the left and 1 on the right, 3 chlorine (Cl) atoms on the right and 0 on the left, and 1 iron (Fe) atom on the right and 0 on the left.

To balance the equation, we can use the following coefficients: ``` Li2S + 2FeCl3 -> 2LiCl + Fe2(SO4)3 ``` This balances the equation, ensuring that the same number of each type of atom is present on both sides [[1]].

2) AgNO3 + NiSO4 -> Similarly, for this equation, we count the number of atoms of each element on both sides. There are 1 silver (Ag) atom on the left and 1 on the right, 1 nitrogen (N) atom on the left and 1 on the right, 3 oxygen (O) atoms on the left and 3 on the right, 1 nickel (Ni) atom on the right and 1 on the left, and 1 sulfur (S) atom on the right and 0 on the left.

Balancing the equation, we get: ``` 2AgNO3 + NiSO4 -> Ag2(SO4)3 + Ni(NO3)2 ``` This balances the equation, ensuring that the same number of each type of atom is present on both sides [[2]].

3) Na2SiO4 + K3PO4 -> Counting the atoms, we find 2 sodium (Na) atoms on the left and 0 on the right, 1 silicon (Si) atom on the left and 1 on the right, 4 oxygen (O) atoms on the left and 4 on the right, 3 potassium (K) atoms on the right and 0 on the left, and 1 phosphorus (P) atom on the right and 0 on the left.

Balancing the equation, we get: ``` 2Na2SiO4 + 3K3PO4 -> 6Na3PO4 + 2K2SiO3 ``` This balances the equation, ensuring that the same number of each type of atom is present on both sides [[3]].

These balanced chemical equations ensure that the law of conservation of mass is obeyed, with the same number of each type of atom on both sides of the equation.
