See attached problem. I am having trouble on all parts of the problem.
Problem numbers 6 and 7 from the following attachment are rather confusing. I completed the problems, but I'm not sure if I did them correctly. I am very confused as to how to figure out how to complete problems 6 and 7. For 6, I was told that the Phosphorous triple bond is much weaker than its single bond and that the Nitrogen ...continues
I have been having trouble figuring out how to do problems 8-10 in the attachment below. I completed the problems, but I would like to make sure that I have the correct answers and that I understand the solutions to the problems.
A) Define entropy. Why is entroy considered an absolute quantity? B) For each of the pairs of substances below, choose the one expected to have the greater absolute entropy. Explain your answer. Assume 1 mol of each substance. i) Cu(s) or C(graphite) at the same temperature and pressure ii) Ne(g) at 5.0atm or Ne(g ...continues
(see attachment) Please complete #1-7. I will have worked on them as well and I would like to compare my answers to see if I'm on the right track. Thank you!
5. Calculate the sodium ion concentration when 60.0 mL of 6.0 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate.
Nitrogen and Hydrogen gases react to form Ammonia. A closed, rigid cylinder contains a total of 0.750 mol of gas at 25 degrees C and 1.10 atm before the reaction takes place; the mole ratio of hydrogen to nitrogen in the cylinder is 3:2. Determine the temperature and pressure of the gas in the cylinder at the end of the reaction ...continues
Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 500. L/min. Carbon dioxide at 223°C and 47 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100% yield?
What is the concentration of a solution in which 5.0 mL of a 4.5 M HCl is diluted to 250 mL of solution?
Vinegar and eggshells reaction
When vinegar and eggshells are combined a reaction ocurrs that produces new chemicals. Show a balanced equation for this reaction.
