Methyl Mercury has a half-life of 50 days in human blood. A 3 oz serving size of cannedalbacore tuna, on average, contains 30 mcg of mercury. The FDA recommends that adultsnever exceed more than 250 mcg of methyl mercury in their bloodstream. If a person eatsone serving of canned albacore tuna every 5 days inde nitely, will they ever exceed 250 mcgin their bloodstream? Explain.

the objects have the same charge.

when the pressure is increased, there will be a shift to the reactants side. decreasing the volume will increase pressure. when you decrease the volume, the gaseous species get more tightly packed of the concentrations of gaseous species increase.

le chatelier's principle says that the system wants to undo this concentration increase so it can decrease pressure.

since the reactants only have 1 mol of gas (only pcl5) and the products have 2 mol of gas (both pcl3 and cl2), it shifts to reactants to decrease concentration, thereby lowering the pressure
