Answer:- 21.4 grams of 
are formed.
Solution:- The balanced equation is:
From this equation, lithium and nitrogen reacts in 6:1 mol ratio. Limiting reactant gives the theoretical yield of the product. We will calculate the grams of the product for the given grams of both the reactants and see which one of them gives the limited amount of the product. This limited amount of the product will be the theoretical yield.
The molar mass of Li is 6.94 gram per mol and for 
It is 28.02 gram per mol. The molar mass of is 34.83 gram per mol. The calculations for the grams of the product for given grams of both the reactants are shown below:
= 
= 
From above calculations, Li gives least amount of the product. So, 21.4 g of are formed.
Human bone does not contain oxygen
False, the radiation from food and medical procedures have very little consequences. The radiation from a nuclear power plant can kill people which makes it a very large problem if not contained properly.

Explanation:
This question is on application of Boyle's law; <u>pressure is inversely proportional to volume</u>.when we inhale air, the diaphragm and the muscles in the ribs contract thus increasing the volume in the lungs.Increased volume of the lungs cause the pressure to decrease.During exhaling, the diaphragm and muscles in the ribs relax, making the lungs to recoil and reduce in volume to force air out.Pressure in the lungs is increased than that in the environment making air to move out.
No, they do not. Hope I helped! :)
