THIS NEEDS TO BE ANSWERED ASAP THIS IS DUE TOMORROW!!! a. Neon is considered a pure substance. What do you observe about the molecules?
b. Could the other molecules in this simulation (argon, oxygen, and water) be considered pure substances? Explain your thinking.
If you answer this correctly I will give brainliest and 100 points!!

Earth's rotation cause the global convention current between the equator and the poles

Ithink that’s it’s b

The second and last option are the answers

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
