The rotten smell of a decaying animal carcass is partially due to a nitrogen-containing compound called putrescine. elemental analysis of putrescine indicates that it consists of 54.50% c, 13.73% h, and 31.77% n. calculate the empirical formula of putrescine. (hint: begin by assuming a 100-g sample and determining the mass of each element in that 100-g sample.)

C2H6N

Explanation:

Putrescine formula is C4H12N2

Assuming 100g sample is present

The percent changes to grams and it is converted to moles by dividing it with the atomic masses.

C= 54.50g/12 = 4.541moles

H = 13.73g/1 = 13.73moles

N= 31.77g/14 = 2.269moles

Divide through with the smallest moles value.

C= 4.541/2.269 = 2

H= 13.73/2.269=6

N= 2.269/2.269=1

Therefore the empirical formula is

C2H6N

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
