Question

PLEASE HELP ME! Draw the Lewis structure for each of the following compounds. Which compound contains two double bonds?

Answer 1

HCN

NH3

O3

CO2

Answer 2

So, Carbon needs four bonds. I gave it three with Mr. Nitrogen, which satisfied Mr. N, and one with Mr. Hydrogen. which satisfied him as well. And the one lone pair with Mr. N ofcourse.

Can you try for the others?

Answer 3

@warz helps if you could explain him as well, rather than just post the solutions :)

Answer 4

CO2??

Answer 5

I am a her. hahah

Answer 6

When the following reaction is balanced with the lowest possible whole number coefficients, what is the coefficient in front of oxygen (O2)?

C2H6 + O2 “yields”/ CO2 + H2O

Answer 7

Oh lol, sorry, "her" then.

balance the equation. balance the no. of atoms of each element in the reactant and product side.

Answer 8

3? for question two

Answer 9

hahahaha yeah well its mostly based on valency CO2 carbon is in group 4 A \and needs 4 more electorns to complete its octect so it must form four bonds oxygen has valency 2 as it need 2 e ok so making co2 they are all trying to get eight e carbon frms two covalent bonds with two o2 ok get the concept

Answer 10

Oops, looks like warz explained the structure of CO2/

anyways, geek, post what you got in your balancing.

Answer 11

i think its 7

Answer 12

2 c2h6+7O2=4 co2+6H2O
