A solution of 0.640 g of epinephrine in 36.0 g of CCl4 elevates the boiling point by 0.490°C. Kb = 5.02 °C m -1 and Kf = 29.8 °C m -1 for CCl4. (a) What is the molality of the solution?
∆Tb= 0.49°C kB= 5.02°C ∆Tb=kb×m0.49=5.02×mm= 0.097molal

If a is numpy array of shape (5,3) and b is of shape (2,4),what is the shape of a (b)?
Assuming the elements of b are valid indices into rows of a, then a[b] will be a 3D array with shape (2,4,3). In your example, that means b should be...

Calculate Keq for this reaction. Is the forward or the reverse reaction favored?
2 NO(g) + O2(g) 2 NO2(g)
when [NO] = 0.050 M,; [O2] = 0.75 M, and [NO2] = 0.25 M.
Keq= 0.25^2 / 0.05^2 x 0.75 =33,3333333.

dentify the Bronsted-Lowry base in the following equation:
HCl(aq) + NO2-(aq) ⇨ HNO2(aq) + Cl-(aq)
A. HCl(aq) B. NO2-(aq) C. HNO2(aq) D. Cl-(aq) E. H2O(l)
Bronsted-Lowry base is the particle, that accepts a proton (by definition). Here NO2- is turning into HNO2. So, NO2- is Bronsted-Lowry base.Answer: B. NO2-(aq)

If 96.0 mL of nitrogen gas reacts with 42.0 mL of oxygen gas, what is the volume of NO2 produced? Assume all gases are at the same temperature and pressure.
N2(g)+O2(g)→NO2(g)
N2(g)+2O2(g)→2NO2(g)we have the excess of nitrogen so calculate everything from oxygen volumeV(O2)=V(NO2) from stoichiometric coefficientsV(NO2)=42mL
