Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation and balance them one by one.

1. S + Cl2 = ? To balance this equation, we need to ensure that the number of sulfur (S) atoms and chlorine (Cl) atoms is the same on both sides. Since there is only one sulfur atom on the left side, we need to put a coefficient of 1 in front of Cl2 to balance the equation. Therefore, the balanced equation is: S + Cl2 = SCl2 [[1]]

2. Mg + O2 = ? In this equation, we have magnesium (Mg) and oxygen (O) as reactants. To balance the equation, we need to ensure that the number of magnesium atoms and oxygen atoms is the same on both sides. Since there is only one magnesium atom on the left side, we need to put a coefficient of 2 in front of Mg to balance the equation. Therefore, the balanced equation is: 2Mg + O2 = 2MgO [[2]]

3. ZnO + P2O5 = ? Here, we have zinc oxide (ZnO) and diphosphorus pentoxide (P2O5) as reactants. To balance the equation, we need to ensure that the number of zinc atoms, oxygen atoms, and phosphorus atoms is the same on both sides. Since there is only one zinc atom on the left side, we need to put a coefficient of 2 in front of ZnO and a coefficient of 5 in front of P2O5 to balance the equation. Therefore, the balanced equation is: 2ZnO + 5P2O5 = 2ZnP4O10 [[3]]

4. Li2O + SO2 = ? In this equation, we have lithium oxide (Li2O) and sulfur dioxide (SO2) as reactants. To balance the equation, we need to ensure that the number of lithium atoms, oxygen atoms, and sulfur atoms is the same on both sides. Since there are two lithium atoms on the left side, we need to put a coefficient of 3 in front of Li2O and a coefficient of 3 in front of SO2 to balance the equation. Therefore, the balanced equation is: 3Li2O + 3SO2 = Li2SO3 [[4]]

5. CO2 + H2O = ? Here, we have carbon dioxide (CO2) and water (H2O) as reactants. To balance the equation, we need to ensure that the number of carbon atoms, oxygen atoms, and hydrogen atoms is the same on both sides. Since there is only one carbon atom on the left side, we need to put a coefficient of 1 in front of CO2 and a coefficient of 2 in front of H2O to balance the equation. Therefore, the balanced equation is: CO2 + 2H2O = CH2O3 [[5]]

6. SiO2 + H2O = ? In this equation, we have silicon dioxide (SiO2) and water (H2O) as reactants. To balance the equation, we need to ensure that the number of silicon atoms, oxygen atoms, and hydrogen atoms is the same on both sides. Since there is only one silicon atom on the left side, we need to put a coefficient of 1 in front of SiO2 and a coefficient of 2 in front of H2O to balance the equation. Therefore, the balanced equation is: SiO2 + 2H2O = H4SiO4 [[6]]

7. BaO + H2O = ? Here, we have barium oxide (BaO) and water (H2O) as reactants. To balance the equation, we need to ensure that the number of barium atoms, oxygen atoms, and hydrogen atoms is the same on both sides. Since there is only one barium atom on the left side, we need to put a coefficient of 1 in front of BaO and a coefficient of 2 in front of H2O to balance the equation. Therefore, the balanced equation is: BaO + 2H2O = Ba(OH)2 [[7]]

8. Ka + H2O = ? In this equation, we have potassium (Ka) and water (H2O) as reactants. To balance the equation, we need to ensure that the number of potassium atoms and hydrogen atoms is the same on both sides. Since there is only one potassium atom on the left side, we need to put a coefficient of 2 in front of Ka and a coefficient of 1 in front of H2O to balance the equation. Therefore, the balanced equation is: 2Ka + H2O = 2KOH [[8]]
