If 2.34 moles of Mg react with 3.56 moles of l2 and 1.76 moles of Mgl2 form, what is the percent yield?
Answer:
40
Explanation:
Your trying to find out the meters so your going to divide 3920J by 10 and 9.8
3920/10/9.8
Losing electrons and forming positive ions
So multiply number of moles x number of atoms/mole = 1.8066 x 10^24 atoms of H2. One mole of any gas at STP has a volume of 22.4 L. So first determine the number of moles of gas you have.
for example do 7

that 's what I think
The element Sodium (Na) has 11 protons and 1 valence electron.
