Answer:
143.03%
Explanation:
You find percent yield by dividing actual yield over theoretical yield and then multiplying by 100
Answer:
<em>Heat</em> is the total energy of molecules moving around. <em>Temprature</em> is a measure of the average energy of molecules motion.
Answer:
D. Earth's northern hemisphere is tilted toward the Sun
Explanation:
You can see in the picture above that the northern hemisphere is past the perpendicular to orbit line to the right.
The balanced equation for the reaction between Mg and O₂ is as follows
2Mg + O₂ --> 2MgO
stoichiometry between Mg and O₂ is 2:1
number of Mg reacted - 4.00 mol
if 2 mol of Mg reacts with 1 mol of O₂
then 4.00 mol of Mg requires - 1/2 x 4.00 = 2.00 mol of O₂
then the mass of O₂ required - 2.00 mol x 32.0 g/mol = 64.0 g
64.0 g of O₂ is required for the reaction
