Answer 2

Chemical Equation 1: CaO + H2SO4 = BaO + HCl

The chemical equation you provided is: CaO + H2SO4 = BaO + HCl.

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's balance the equation step by step:

1. Start with the calcium (Ca) atoms. There is one Ca atom on the left side and one on the right side, so the equation is balanced in terms of Ca.

2. Next, let's balance the oxygen (O) atoms. There is one O atom in CaO and one O atom in BaO. On the left side, there is one O atom in H2SO4. To balance the O atoms, we need to add another H2SO4 molecule on the left side. The equation becomes:

CaO + H2SO4 + H2SO4 = BaO + HCl

3. Now, let's balance the hydrogen (H) atoms. There are two H atoms in H2SO4, so we have four H atoms on the left side. On the right side, there is one H atom in HCl. To balance the H atoms, we need to add three more HCl molecules on the right side. The equation becomes:

CaO + H2SO4 + H2SO4 = BaO + HCl + HCl + HCl

4. Finally, let's balance the sulfur (S) atoms. There is one S atom in H2SO4, so we have two S atoms on the left side. On the right side, there is no S atom. To balance the S atoms, we need to add a BaSO4 molecule on the right side. The equation becomes:

CaO + H2SO4 + H2SO4 = BaO + HCl + HCl + HCl + BaSO4

Now, the equation is balanced in terms of the number of atoms on both sides.

Please note that this balanced equation assumes that the reaction goes to completion and that all reactants are fully consumed.

Chemical Equation 2: BaO + HCl = Na2O + HNO3

The chemical equation you provided is: BaO + HCl = Na2O + HNO3.

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's balance the equation step by step:

1. Start with the barium (Ba) atoms. There is one Ba atom on the left side and none on the right side. To balance the Ba atoms, we need to add a Ba(NO3)2 molecule on the right side. The equation becomes:

BaO + HCl = Na2O + HNO3 + Ba(NO3)2

2. Next, let's balance the chlorine (Cl) atoms. There is one Cl atom in HCl on the left side and none on the right side. To balance the Cl atoms, we need to add two more HCl molecules on the right side. The equation becomes:

BaO + HCl + HCl + HCl = Na2O + HNO3 + Ba(NO3)2

3. Now, let's balance the sodium (Na) atoms. There are no Na atoms on the left side and two Na atoms in Na2O on the right side. To balance the Na atoms, we need to add two NaOH molecules on the left side. The equation becomes:

BaO + HCl + HCl + HCl + 2NaOH = Na2O + HNO3 + Ba(NO3)2

4. Finally, let's balance the oxygen (O) and nitrogen (N) atoms. There are two O atoms in BaO on the left side and three O atoms in HNO3 on the right side. To balance the O atoms, we need to add a H2O molecule on the left side. The equation becomes:

BaO + HCl + HCl + HCl + 2NaOH + H2O = Na2O + HNO3 + Ba(NO3)2

There are two N atoms in HNO3 on the right side. To balance the N atoms, we need to add a NH4NO3 molecule on the left side. The equation becomes:

BaO + HCl + HCl + HCl + 2NaOH + H2O + NH4NO3 = Na2O + HNO3 + Ba(NO3)2

Now, the equation is balanced in terms of the number of atoms on both sides.

Please note that this balanced equation assumes that the reaction goes to completion and that all reactants are fully consumed.

Chemical Equation 3: Na2O + HNO3 = ?

The chemical equation you provided is: Na2O + HNO3 = ?

To balance this equation, we need to know the products of the reaction. Without the products, we cannot balance the equation accurately.

If you provide the products of the reaction, I can help you balance the equation.
