Answer:
8
Explanation:
Methyl anion (CH₃⁻)
Valence electrons of carbon = 4
Valence electrons of hydrogen = 1
Charge = -1 which means addition of 1 electron
The total number of the valence electrons = 4 + 3(1) + 1 = 8
<u>In the Lewis structure of anion also, 1 lone pair and 3 bond pairs on the carbon atom which corresponds to 8 valence electrons.</u>
Answer:
Equation for Calcium Hydroxide Dissolving in Water | Ca(OH)2 + H2O.
When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.
Answer: The number of moles of
produced will be, 3.61 moles.
Explanation : Given,
Mass of
= 83.0 g
Molar mass of
= 23 g/mol
First we have to calculate the moles of ![Na](https://tex.z-dn.net/?f=Na)
![\text{Moles of }Na=\frac{\text{Given mass }Na}{\text{Molar mass }Na}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DNa%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%20%7DNa%7D%7B%5Ctext%7BMolar%20mass%20%7DNa%7D)
![\text{Moles of }Na=\frac{83.0g}{23g/mol}=3.61mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DNa%3D%5Cfrac%7B83.0g%7D%7B23g%2Fmol%7D%3D3.61mol)
Now we have to calculate the moles of ![NaCl](https://tex.z-dn.net/?f=NaCl)
The balanced chemical equation is:
![2Na+Cl_2\rightarrow 2NaCl](https://tex.z-dn.net/?f=2Na%2BCl_2%5Crightarrow%202NaCl)
From the reaction, we conclude that
As, 2 mole of
react to give 2 mole of ![NaCl](https://tex.z-dn.net/?f=NaCl)
So, 3.61 mole of
react to give 3.61 mole of ![NaCl](https://tex.z-dn.net/?f=NaCl)
Therefore, the number of moles of
produced will be, 3.61 moles.
