Answer:
18 electrons
Explanation:
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it.
What are you asking? you put the answer in your question. consumer
The answer is Cl (chlorine)
equalize the coefficients:
Al(NO3)3+3NaCl=3NaNO3+AlCl3
according to the equation 1 mol Al(NO3)3 reacted with 3 moles NaCl. hence, 4 moles Al(NO3)3 should react with 12 moles NaCl, and 9 moles reacted NaCl. So NaCl is limiting, we decide further on this reagent.
\frac{9}{3}=\frac{x}{3}
3
9
=
3
x
x=9
9 moles NaNO3
It can be done by you only
- First observe the figure or model .
- Then note the observations about its molecular structures .
- Then write it uses and why it is commercial most usable.
