What is the total entropy change for the decomposition of hydrogen peroxide.
2H2O2(l) ---> 2H2O(l) + O2(g)
Given
H2O2(l)
(J/mol x K) = 109.6
(kJ/mol) = -187.8
H2O(l)
(J/mol x K) = 69.9
(kJ/mol) = -285.8
O2(g)
(J/mol x K) = 205.0
(kJ/mol) = 0
- The probability that a student must stop at any one traffic light going to NUST from Havana is 0.2. There are 15 traffic lights on the Journey.
a) what is the probability that a student will stop at exactly two of the 15 set of traffic lights?
b) what is the probability that a student will stop at 3 or more of the 15 set of traffic lights?
Assume that the egg industry is perfectly competitive and is in long-run equilibrium with a perfectly elastic long-run industry supply curve. Health concerns about cholesterol then lead to a decrease in demand. Construct a figure similar to Figure 7-7 from your pdf text (page 263 of 698), showing the short-run behavior of the industry and how long-run equilibrium is reestablished.
A teacher realizes that his students' marks on a statistic test are normally distributed with a mean of 62 and a standard deviation of 15. If the teacher wishes to assign minimum marks for grade B is referring to the top 30 per cent of the students' marks in the class, how many marks are required to get a minimum mark for grade B?
Find the volume of the solid formed by the region bounded by the functions
y = 6 - 2x - x^2, y = x + 6
Using the same universal set, find the set specified by each of these bit strings.
(i) 11 1100 1111 (ii) 01 0111 1000 (iii) 10 0000 0001
A fan delivers 4.7 cu.m/sec at a static pressure of 5.08 cm of water when operating at a speed of 500 rpm. The power input required is 2.963 kW. If 7.05 cu.m/sec are desired in the same fan and installation, what is the new angular speed in rpm?
{x | x is the square of an integer and x < 50}
