2. a. i. Iron reacts with H2SO4 according to the equation: Fe(s) + H2SO4(aq) - → FeSO4(aq) + H2(g). Calculate the mass of FeSO4 that would be produced by 0.5mole of Fe. ii. Calculate the volume of CO2 produced when 5.8g of Na2CO3 reacted with excess HNO3 Na2CO3(s) + 2HNO3(aq) 2NaNO3(aq) + CO2(g) +H20(l)

Why is retrograde motion an apparent motion

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
