12h-17-h+16-2h =12h-3h-17+16 =9h-1,if you mean the value of h,then h =1/9
It is: 11h
Carbonic acid, H2CO3
H is 30

The complete ionic equation for this reaction is: 2H⁺(aq) + SO₄²⁻(aq) + Ca²⁺(aq) + 2I⁻(aq) → CaSO₄(s) + 2H⁺(aq) + 2I⁻(aq)
2h + 2h + 2h = 6h
The balanced chemical equation for this reaction is: FeS + 2H⁺ → Fe²⁺ + H₂S
The balanced symbol equation for making water is: 2H₂ + O₂ → 2H₂O.
H2SO4(aq) + CaI2(aq) -> CaSO4(s) + 2HI(aq)
First set up the equation: 2h+10=40 Then get the variable alone by subtracting 10 from each side: 2h=30 And continue by dividing both sides by two 2h=30 ______ 2 2 h=15 So your answer is h=15
- 3h - 2h + 6h + 9 = h + 9
The net ionic equation of the reaction given is: 2H⁺(aq) + SO₄²⁻(aq) + Ca²⁺(aq) + 2I⁻(aq) → CaSO₄(s) + 2H⁺(aq) + 2I⁻(aq).
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I
The balanced chemical equation for hydrogen reacting with chlorine to form hydrogen chloride is: H2 + Cl2 → 2HCl.
The net ionic equation for the given reaction is: 2H+ + SO4^2- + Ca^2+ + 2I- → CaSO4(s) + 2H2O. This equation highlights the ions that participate in the reaction and the formation of the solid calcium sulfate and water.
The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
