Answer:
Theoretical yield = 40.8g
Explanation:
4Al + 3O2 ----] 2Al2O3
<h3>if 27.0g of Al ----] 102.0g of 2Al2O3</h3><h3>therefore 10.8g -----] xg</h3>
10.8g×102.0g/ 27.0g
theoretical yield = 40.8 g
Yes because the group number is the number of electrons in their outermost shell.
Answer:
2
Explanation:
K shell=2
L shell=4
Since carbon has an atomic no of 6 it electron shells are 2 namely kshell and lshell
Answer : The number of oxygen atoms present in glucose are
Explanation :
First we have to calculate the moles of glucose.
Molar mass of glucose = 180 g/mole
Now we have to calculate the number of oxygen atoms.
The formula of glucose is, .
In the glucose molecule, there 6 atoms of carbon, 12 atoms of hyrogen and 6 atoms of oxygen.
As, 1 mole of glucose contains number of oxygen atoms
So, 0.667 mole of glucose contains number of oxygen atoms
Therefore, the number of oxygen atoms present in glucose are
