Add charges, single electron dots, and/or pairs of dots as appropriate to show the Lewis symbols for the most stable ion of each element. Treat n- 4 as the valence shell in all cases.
A sample of impure limestone (calcium carbonate) when heated
yields calcium oxide and oxygen gas. A 1.506 g sample of limestone
gives 0.558 g of carbon dioxide. This is less than what was
expected. Calculate the percent of limestone in the impure
sample.

An experiment consists of tossing a single die and observing the
number of dots that show on the upper face. Events A,
B, and C are defined as follows.
A:
Observe a number less than 4.
B:
Observe a number less than or equal to 2.
C:
Observe a number greater than 3.
Find the probabilities associated with the events below using
either the simple event approach or the rules and definitions from
this section. (Enter your probabilities as fractions.)...
