calculate the liters of a .20 M solution that can be made using 126.0 grams HNO3
Calculate the differences in energy between ΔU and ΔH for the following reactions at constant pressure at 25oC.( use ΔH = ΔU + PΔV)
a) CH3CH2CH3(g) + 5O2(g) ⇔ 3CO2(g) + 4H2O (l)
b) C6H12O6 (s)+6O2(g) ⇔ 6 CO2(g) + 6 H2O(l)
c) Mg (s) + 2H + (aq) ⇔ Mg2(aq) + H2(g)
Consider the following economy and use the Keynasian model to answer the succeeding questions.
C = 350 mil + 0.85Yd
I = 175 mil
G = 300 mil
X = 170 mil
Z = 120 mil
T = 0,15Y
Yf = R3100 million
Equilibrium Income: Y = C + I + G + (X - Z)
Disposable Income: Yd = (1 - t)Y
Question 1. Calculate the Mutiplier.
What is the concentration of hydroxide ions in 750 mL of a solution containing the maximum amount of dissolved calcium hydroxide?
Car repairs An owner of an auto repair shop wishes to organise his team of mechanics at the beginning of the day. To make the distribution of work equal, he organises cars with an even amount of faults into bay 1 and cars with an odd amount of faults into bay 2. There are nine cars in total Write the pseudocode for the problem, then write a Java program to separate the even and odd number of car faults. Have all even numbers displayed first, then odd numbers at the end. The repairs required for each car are as follows. 18, 14, 12, 6, 4, 21, 19, 9, 3 Hint: WHILE LOOPS and IF
Task 2: Internet traffic As a digital business analysist, you have been asked by your line manager to supply the last seven months traffic figures to your company’s website. At the moment, the traffic numbers are not in ascending order. Write the pseudocode to solve the initial problem and then write a Java algorithmic program to sort the array of given traffic figures. The traffic numbers to sort correctly are: 2, -17, 8, 26, 1, 0, 84 Hint: Bubble sort

Question 1. What is the value of the marginal propensity to consume in this model?
Task 1:
Building contractor
You are developer and you wish to build five new houses, all from wood and all uniform.
Each house has 3 rooms, all with exactly the same dimensions, i.e. 2m x 4m. Wood prices
have been set at £6.00 per meter.
You need to determine the total cost of the build of all five houses. Initially, you will need
to write the pseudocode to solve the following problem, define the variable name and data
types, plus write the code to solve the total build cost.
Hint: Determine the area of each room in each house and the total area of all rooms
combined. Thus, giving the total price of the construction. in java
The Hamster Pet Farm ordered a pair of black haired hamsters for breeding. The first generation were all black hamsters. When the Pet Farm mated hamsters of the first generation, one of the offspring turned out to be white. The Pet Farm said this must have been caused by a "hidden gene." Why did this happen? Explain "hidden gene' and how one of the offspring could have been white in this family of hamsters. Explain how you would keep track of the different generations. How could the owner get pure black hamsters. You must use these words to explain the situation or you lose points. Punnett Square, hybrid, pure, dominant, recessive, predict or chance, and pedigree. This is worth 13 points so it should be a paragraph NOT one sentence.
A company sends a random sample of 16 of its sales- people to a course designed to increase their moti- vation and, hence, presumably their effectiveness. In the following year these people generated sales with an average value of $625,000 and a sample stan- dard deviation of $80,000. During the same period, an independently chosen random sample of 10 sales- people who had not attended the course obtained sales with an average value of $608,000 and a sample standard deviation of $73,000. Assume that the two population distributions are normal and have the same variance. Find a 90% confidence interval esti- mate for the difference between the population mean sales for salespeople who attended the motivational course and for those salespeople who did not attend the course.
