Question 1

Given the thermochemical equation 2SO2(g) + O2(g) → 2SO3(g),  ΔH°rxn= –198 kJ/mol, how much heat is evolved when 600. g of SO2 is burned?
◦ 5.46 × 10–2 kJ
◦ 928 kJ
◦ 1.85 × 103 kJ
◦ 3.71 × 103 kJ
◦ 59,400 kJ

Question 2

Glycine, C2H5O2N, is important for biological energy.  The combustion reaction of glycine is given by the equation
         4C2H5O2N(s) + 9O2(g) → 8CO2(g) + 10H2O(l) + 2N2(g)       ΔH°rxn = –3857 kJ/mol
Given that ΔH°f[CO2(g)] = –393.5 kJ/mol and ΔH°f[H2O(l)] = –285.8 kJ/mol, calculate the enthalpy of formation of glycine.
◦ –3,178 kJ/mol
◦ –964 kJ/mol
◦ –537.2 kJ/mol
◦ –268.2 kJ/mol
◦ 2,149 kJ/mol

Vital signs (blood pressure, temperature, pulse rate, respiration rate) should be taken before any drug administration. Patients should be informed not to use tobacco or caffeine at least 30 minutes before their appointment.

Did you know?

It is difficult to obtain enough calcium without consuming milk or other dairy foods.

Did you know?

Many supplement containers do not even contain what their labels say. There are many documented reports of products containing much less, or more, that what is listed on their labels. They may also contain undisclosed prescription drugs and even contaminants.

Did you know?

Human kidneys will clean about 1 million gallons of blood in an average lifetime.

Did you know?

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
