The average human fart expels methane (CH4) and carbon dioxide (CO2) gas. What is the ratio of their diffusion rates? a)1.66
b)0.364
c)0.603
d)2.75

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

Give the orbital configuration of the phosphorus (p) atom.
