Element C will have 5 protons
Answer:
Explanation:
Identify all of the compounds present:
- aqueous copper(II) sulfate: we have copper charged as 2+, sulfate anion has a charge of 2-. This means the charges are balanced if we take 1 ion of each to give ;
- solid iron metal: iron metal is Fe, then including the state of iron, we have ;
- aqueous iron(II) sulfate: iron has a charge of 2+, sulfate has a charge of 2-, so the positive charge balances the negative charge to give a formula of ;
- solid copper metal: copper metal is Cu, then including the state of copper, we have .
We then have a reaction:
Answer:
Theoretical moles of V are 1.6 moles
Explanation:
The theoretical yield of a reaction is defined as the amount of product you would make if all of the limiting reactant was converted into product.
In the reaction:
V2O5(s) + 5Ca(i) → 2V(i) + 5CaO(s)
Based on the reaction, 1 mol of V2O5 needs 5 moles of Ca for a complete reaction. As there are just 4 moles, <em>limiting reactant is Ca.</em> As there are produced 2 moles of V per 5mol of Ca, Theoretical moles of V are:
4 moles of Ca × (2mol V / 5Ca) = <em>1.6 moles of V</em>
