Post a New Question

Posted by on .

I just took a chemistry midterm and our teacher let us keep the exam. I was wondering if you could let me know if I was right or wrong for the following questions. I can ask my professor later for details.

Which of the following are best described as strong acids?
(a) H2SO4 and HI
(b) HNO2 and benzenesulfonic acid
(c) Both a and c
(d) Both a and b
I CHOSE (A) AS MY ANSWER

In the reaction 2NO(g) + Cl2(g) = 2NOCl(g) an increase in the pressure, keeping the temperature constant will
(a) increase the value of Kp
(b) decrease the value of Kp
(c) increase the concentration of NOCl
(d) both a and b
(e) both a and c
I CHOSE (C) WAS MY ANSWER

When hemoglobin, Hb, reacts with oxygen, O2, we get oxyhemoglobin HbO2:
Hb(aq) + O2(g) --> HbO2 (aq)
At high altitude, the partial pressure of O2 is lower. To get adequate HbO2 to live, an organism would likely
(a) produce less Hb
(b) produce more Hb
(c) reduce HbO2
(d) both b and c
(e) none of these
I CHOSE (B) AS MY ANSWER

THANK YOU!

    If this is a take home exam, I don't want to help you cheat.

    No this was the first chemistry midterm for CHEM 1C taken for the summer session I at UCI. I'm in the same class and I have the questions too. Our professor didn't provide us with the key which I have no idea why if he wanted us to learn from for the upcoming tests.
    Please help
