Concept explainers
3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings
Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can.
(a) How many valence electrons are present in a molecule of N20?
(b) Write two equivalent contributing structures for this molecule. The connectivity in nitrous oxide is N−N−O.
(c) Explain why the following is not an acceptable contributing structure:

Therefore, they show some colors. Thus, hydrates can be used to detect the moisture in the environment. Let's say you are working in a laboratory with a group and you are the only student who has taken chemistry courses. Your laboratory received a sample of cobalt(II) chloride which has the formula CoCl2·xH2O. Let's say your boss asked you to find the formula of this hydrate salt sample since you are the only chemist there. From your laboratory experience, simply explain the experimental procedure you would follow to find the formula of this unknown sample. Then, use the given data for the calculation part.
