The analysis on a mass basis of an ideal gas mixture at 30°f, 15 lbf/in.2 is 25% co2, 30% co, and 45% o2.
determine:
(a) the analysis in terms of mole fractions.
(b) the apparent molecular weight of the mixture.
(c) the partial pressure of each component, in lbf/in.2
(d) the volume occupied by 10 lb of the mixture, in ft3.

An exothermic reaction is conducted in an insulated calorimeter filled with water. the calorimeter is then sealed so that there is no heat exchanged between the contents of the container and the surrounding air. which of the following statements is true about the reaction?

When an object falls through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance? (one word answer)

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
