Answer:
46.0g of Iron are produced
Explanation:
Based on the chemical reaction:
FeO(l) + Mg(l) → Fe(l) + MgO(s)
<em>1 mole of Iron (II) oxide reacts per mole of Mg to produce 1 mole of iron</em>
<em />
To solve this question we need to convert each mass of reactant to moles using its respectives molar masses in order to find limitng reactant. Moles of limiting reactant = Moles of iron produced:
<em>Moles FeO (Molar mass: 71.85g/mol):</em>
80.0g * (1mol / 71.85g) = 1.11moles FeO
<em>Moles Mg (Molar mass: 24.305g/mol)</em>
20.0g * (1mol / 24.305g) = 0.823 moles Mg
As moles of Mg < Moles FeO, Mg is limiting reactant and the moles of Fe are 0.823 moles.
The mass of Iron produced is:
0.823 moles Fe * (55.845g/mol) =
46.0g of Iron are produced
Because it’s the closest part of the earth to the sun. Basically the sun’s rays hit there more than anywhere else.
Hey there,
Your question states: Why is ice less dense than liquid water?
There reason why Ice is less dense than liquid is because ice has compact molecules that are tight together and they stay still. But as for water, those molecules are lose and they are more free than ice.
Hope this helps.

It is called electron affinity. It increase as you go to the right of the periodic table.
