Many enzymes are inhibited irreversibly by heavy metal ions such as hg2+ , cu2+ , or ag+ , which can react with essential sulfhydryl groups to form mercaptides. enz−sh+ag+⟶enz−s−ag+h+ the affinity of ag+ for sulfhydryl groups is so great that ag+ can be used to titrate −sh groups quantitatively. to 10.0 ml of a solution containing 3.4 mg/ml of a pure enzyme, an investigator added just enough agno3 to completely inactivate the enzyme. a total of 0.134 μmol agno3 was required. calculate the minimum molecular weight ) of the enzyme.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

here are some of the ways in which chemical and nuclear reactions differ.
