Using Boyle's law:
\( P_1 V_1 = P_2 V_2, \)
substitute \(P_1 = 50\) atm, \(V_1 = 50\) L, and \(P_2 = 1\) atm:
\( V_2 = \frac{P_1 V_1}{P_2} = \frac{50 \times 50}{1} = 2500 \text{ L}. \)
(Zn + 4HNO_3 Zn(NO_3)_2 + 2H_2O + 2NO_2)
32.5 g of zinc reacts with concentrated nitric acid as given in the above equation.
(a) How many moles of zinc was required in the reaction?
(b) Find the mass of nitric acid needed to react with 32.5 g of zinc.
(c) Find the volume of nitrogen dioxide liberated in (b).
(Atomic weight: H = 1, N = 14, O = 16, Zn = 65)
Identify the taxa that constitute a paraphyletic group in the given phylogenetic tree.
The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
