Question 1

How much heat is absorbed/released when 10.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) according to the following chemical equation?

4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l)ΔH° = +1168 kJ

◦ 171.5 kJ of heat are released.
◦ 686.0 kJ of heat are released.
◦ 171.5 kJ of heat are absorbed.
◦ 686.0 kJ of heat are absorbed.

Question 2

How much heat is absorbed when 20.00 g of C(s) reacts in the presence of excess SO2(g) to produce CS2(l) and CO(g) according to the following chemical equation?

5 C(s) + 2 SO2(g) → CS2(l) + 4 CO(g)ΔH° = +239.9 kJ

◦ 159.9 kJ
◦ 79.97 kJ
◦ 959.3 kJ
◦ 399.5 kJ

Many of the drugs used by neuroscientists are derived from toxic plants and venomous animals (such as snakes, spiders, snails, and puffer fish).

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Did you know?

Asthma attacks and symptoms usually get started by specific triggers (such as viruses, allergies, gases, and air particles). You should talk to your doctor about these triggers and find ways to avoid or get rid of them.
