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:
2Al + 3CuSO4 → Al2(SO4)3 + 3Cu
Explanation:
I THINK
First you want to convert the Celsius to Kelvin, so 10C will be 283.15K, and 100C will be 373.15K.
Then, we have to look at the PVnT relationships to determine what to do. Since T increases, that must mean V increases. And since pressure increases, V will increase from that too. I believe it can be assumed # of particles then stay constant.
1) The first ratio is your given value
20mL
———
1
2) you multiply the above by the ratio which favors the relationships: so if the given value is supposed to rise, then the bigger number should be on top, and vice versa. Since no info on # particles is included, that’ll be excluded.
.... 373.15K x 10atm
———— ————
283.15K 1 atm
So 1) multiplied by 2) gives 263.57 mL, which means the answer is none of the choices.
