Draw lewis structures for the following. include any resonance structures. if more thanone lewis structure can be drawn, use formal charges to decide on the most preferredlewis structure.
1.ch4
2.bf3
3.hcn
4.nh4
5. h2o
6.clo3^-

D. h2o + h2o > h3o + oh- confirmed.

Ans() ; the burning of them contributes to global warmingthey come from decayed organic material;

Answer is: value of q is 5·10⁻⁶m.chemical reaction: mg²⁺(aq) + co₃²⁻(aq) → mgco₃(s).c(mg²⁺) = 2.5·10⁻³ m; concentration of magnesium cations.c(co₃²⁻) = 2.00·10⁻³ m; concentration of carbonate anions.q = c(mg²⁺)  · c(co₃²⁻).q = 2.5·10⁻³ m  · 2.00·10⁻³ m.q = 5·10⁻⁶m.q = 0.000005 m.
