Through their nose.
Most moles have highly adapted noses that filter out dirt particles well.
Mole holes usually have an end where air comes in.
Moles, in fact, can be buried alive if their holes collapse.
Through their nostrils and mouth.
To blow up a 1.2 balloon, it requires 0.18 moles of exhaled air (3 breaths x 0.060 moles/breath). For a 3.0 balloon, which is 2.5 times larger, it would require 0.45 moles of air (0.18 moles x 2.5).
They are able to survive on much lower levels of oxygen and higher levels of CO2 than other mammals, because of the ability of their blood to carry more CO2.
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
this is a easy one. There are only 0.04166 moles.
The mole ratio to convert from moles of a to moles of b is determined by the coefficients of a and b in the balanced chemical equation. For example, if the balanced equation is 2A + 3B -> 4C, the mole ratio would be 3 moles of B for every 2 moles of A.
2 moles of Ca and 4 moles of OH
From the balanced equation, 2 moles of A3 react with 3 moles of B2 to produce 6 moles of AB. Therefore, if 10 moles of A3 are reacted, the ratio of moles of AB produced would be (10 moles A3 / 2 moles A3) * 6 moles AB = 30 moles AB.
Of course 6 moles.
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
For every 2 moles of A3, 3 moles of B2 react to form 6 moles of AB. Since we have 10 moles of A3, we need to double the moles of B2 reacting, which would be 15 moles of B2 to fully react with the 10 moles of A3. This would produce 30 moles of AB.
