What happened to the air in the ice in Antartica? I heard the ice deep in Antartica is very clear. Why doesn't it have little air bubbles like ice cubes? What happened to all that air?

I am considering a move to New Zealand's North Island, and would like to choose my future hometown wisely. Apart from the usual considerations, one thing I want to be careful about is the volcanoes. Of course, they haven't erupted much in the past, but who knows what they are up to in the long run.
I wouldn't want to have to get up from the couch because of it then, let alone find myself shoveling lava from my veggie patch, even though it may be a great fertilizer.
How much "Safety Distance" from a volcano is advisable as a minimum, what do you think?
10km?
50km?
100?

1. Some rocket engines use a mixture of hydrazine, N2 H4, and hydrogen peroxide, H2 O2, as the propellant. The reaction is given by the following equation.

N2H4 (l) + 2H202 (l) ---> N2 (g) + 4H2O (g)

Side question: Why does the need of (l) liquid or (g) or aq(which is aqueous, dissolving in water) need to be specified. I've been doing problems with these signs since I started balancing redox reactions several chapters in general chemistry.. it hasn't seemed to affect the final answer.

a. Which is the limiting reactant in this reaction when 0.750 mol N2H4 is mixed with 0.500 mol H2O2?

b. How much of the excess reactant, in moles, remains unchanged?

c. How much of each product, in moles, is formed/

My work:
a. answer: 0.750 mol N2H4 produces 3 mol H20 ( I just looked at the ratios of H20 produced from each amount. )

b. I don't know how to find that. (????)

c. I put 0.25 mol N2, and 1 mol H20 (from plug, but I don't see why you can't plug in 0.75 mol N2H4 to find this answer)

why can't they just recapture it and put him back in cage? instead of firing gunshot they can give him tranquilizer too.

I'm just researching farming for the future. A few questions:

Cows - What is the best dairy breed (in your opinion)

Chickens - Best egg layers, breed

Goats - Best breed (trying to decide between dairy cows and goats... what do you think?)

What do you need to know before starting a (small) farm? Feed, fencing, housing, etc. Things that most people forget to tell you?

Also, how to get rid of leafminers (attacking tomatoes) and tiny caterpillars who attack spinach? We have an organic garden.

I'm going to check out a few of the local farms for more help, but any info is helpful.

For example, Neutralization reactions like these below (but that DO NOT have CO2 as an end product, but rather some other harmless gas):

HC2H3O2 + NaHCO3 ===> NaC2H3O2 + H2CO3 H2CO3 ===> H2O + CO2

MgCO3(s) + 2 HCl(aq) -----> MgCl2(aq) + H2O(l) + CO2(g)
