creativ13 [48]

A microbiologist was surprised when he could not recover Helicobacter pylori from gastric biopsies in which organisms were seen in the tissue sections. He was advised to switch from the Campy BAP selective medium to Skirrow's blood agar because the latter is free of cephalothin.

  • A broad-spectrum cephalosporin antibiotic called cephalothin is used to treat severe bacterial infections in the urinary tract, skin, bones, and lower respiratory tract.
  • A beta-lactam, first-generation cephalosporin antibiotic with bactericidal activity, cephalothin is semi-synthetic.
  • Penicillin-binding proteins (PBP) on the inner membrane of the bacterial cell wall are bound by cephalothin and rendered inactive.
  • PBPs take involvement in the last phases of bacterial cell wall construction as well as the remodeling of the cell wall during cell division.
  • PBP inactivation hinders the cross-linking of peptidoglycan chains, which is essential for the strength and stiffness of bacterial cell walls.

Nitrogen gas reacts with hydrogen gas to form ammonia What are reactants in this chemical reaction?
krek1111 [17]

1 mol 2 mol  

84g of N2(g) = 84/28 = 3 mol of N2(g)  

From the above reaction 1 mol of N2(g) gives 2 mol 0f NH3(g). So 3 mol of N2(g) should give 6 mol or (6x17) 102 g of NH3(g). But we are getting only 85.0 g of NH3.  

Hence %yield of NH3 = 100x85.0/102 = 83.3%  

Answer D. is correct.  

2. 2HgO (s) --------------------- 2Hg (l) + O2 (g)  

2 mol 2 mol 1 mol  

4 mol 4 mol 2 mol  

As only 1.5 mol of O2 is obtained, so % yield = 1.5x100/2 = 75.0%  

Moreover 603 g of Hg = 603/200.59 = 3.00 molof Hg. Considering this also  

% yield = 3x100/4 = 75%
