The answer is Iron(II) Hydrogen Carbonate. It can also be known or referred as Ferrous Hydrogen Carbonate or even Iron(II) Bicarbonate. The known formula for this chemical is Fe(HCO3)2. The Molar Mass of this chemical is known as 177.8787. Here are some chemical reactions that may be equivalent to this chemical: FeCO3 + H2CO3 = Fe(HCO3)2; or Fe(HCO3)2 = FeCO3↓ + CO2 + H2O; or Fe(HCO3)2 + 2HNO3 = Fe(NO3)2 + 2H2O + 2CO2

Answer:
0.641 moles of ethane
Explanation:
Based on the equation:
C2H6(g) + 7/2O2(g) → 2CO2(g) + 3H2O(l)
We can determine ΔH of reaction using Hess's law. For this equation:
<em>Hess's law: ΔH products - ΔH reactants</em>
ΔH = {2ΔHCO2 + 3ΔHH2O} - {ΔHC2H6}
<em>Pure monoatomic substances have a ΔH = 0kJ/mol; ΔHO2 = 0kJ/mol</em>
<em />
ΔH = {2*-393.5kJ/mol + 3*-285.8kJ/mol} - {-84.7kJ/mol}
ΔH = -1559.7kJ/mol
That means when 1 mole of ethane is in combustion there are released 1559.7kJ of heat. To produce 1.00x10³kJ there are needed:
1.00x10³kJ * (1mole ethane / 1559.7kJ) =
<h3>0.641 moles of ethane</h3>
The energy increases because the molecules in water move faster
