Ca(SO3)
Ca + H2SO4 = CaSO4 + H2
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
CaSO4 is the chemical formula of calcium sulfate.
Reactive metal + acid --> salt + hydrogen Sulphuric acid makes sulphate salts, so: Calcium + sulphuric acid --> calcium sulphate + hydrogen (As a symbol equation: Ca + H2SO4 --> CaSO4 + H2)
The net ionic equation is SO42- + Ca2+ CaSO4.
Ca(OH)2 + H2SO4 >> CaSO4 + 2H2O
The chemical equation for the above reaction is CaHPO4 + NaHSO4 → NaH2PO4 + CaSO4.
Ca + H2SO4 = CaSO4 + H2
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
Ca + H2SO4 --> CaSO4 + H2
Ca(OH)2 + H2SO4 = CaSO4 + 2 H2O
CaSO4 is the chemical formula of calcium sulfate.
Na2SO4+CaCl2 =====> CaSo4+2NaCl
To balance the number of sulfate ions on each side of the equation, a coefficient of 3 should be placed in front of CaSO4. This will give a total of 3 sulfate ions on each side of the equation.
They react to give calcium sulfate and water, though the reaction is not very fast because the calcium sulfate is poorly soluble. We sometimes use an equals sign instead of an arrow in a chemical equation but we read it as 'gives' rather than 'equals', because we are not saying the substances are the same thing.
