Answer:
0.6 moles of CaO will produced.
Explanation:
Given data:
Mass of calcium = 23.9 g
Moles of CaO produced = ?
Solution:
Chemical equation:
2Ca + O₂ → 2CaO
Number of moles of calcium:
Number of moles = mass/ molar mass
Number of moles = 23.9 g / 40 g/mol
Number of moles = 0.6 mol
Now we will compare the moles of calcium and CaO.
Ca : CaO
2 : 2
0.6 : 0.6
0.6 moles of CaO will produced.
It means it will only allow some to go through but not all.
Yes because an organic compound is any member of large class of gaseous liquid or solid chemical compound whose molecules contains carbon
2 H2 + O2 = 2 H2O
1 mole O2 --------------- 2 moles H2O
13.35 moles O2 -------- ( moles H2O)
moles H2O = 13.35 x 2 / 1
<span>= </span>26.7 moles of H2O
