Please help balance the following chemical equations:
1. [tex]\text{Na}_2\text{SO}_3 + \ldots = \text{H}_2\text{SO}_4[/tex]
2. [tex]\text{CaSO}_3 + \ldots = \text{H}_2\text{SO}_4[/tex]
3. [tex]\text{SO}_2 + \ldots = \text{MgSO}_3[/tex]
4. [tex]\text{Ca}_3(\text{PO}_4)_2 = \text{P}[/tex]
5. [tex]\text{H}_3\text{PO}_4 + \ldots = \text{Ca(H}_2\text{PO}_4)_2[/tex]
6. [tex]\text{P} + \ldots = \text{Mg}_3\text{P}_2[/tex]
7. [tex]\text{SiO}_2 + \ldots = \text{Mg}_2\text{Si}[/tex]
Answer (2)
One adds water to the first two, MgS for the third, the 4th requires quite a decomposition (malformed substance -- probably Ca3(PO4)2 ), 5th is with hydrogen, 6 with atomic magnesium while the 7th also with atomic magnesium.
To balance the chemical equations provided, you must match the number of atoms of each element in both the reactants and products. Each equation requires specific adjustments, such as adding water or other reactants to maintain this balance. The adjustments ensure that the laws of conservation of mass are upheld in the reaction equations.
