These questions concern waste disposal in the Solubility Rules lab. Select the correct response from each pull-down menu. (a) All of the solutions prepared in this experiment should be
(b) It is a good idea to have a in the work area to collect waste during the experiment.
(c) A of deionized water can be used to rinse the solutions into the beaker.
(d) Use the amount of water possible, to avoid creating of waste solution.

a) discarded in the waste container

b) labelled beaker

c) squeeze bottle

d) minimum, large volume

Explanation:

Every chemical process produces waste. Disposal of chemical waste must be carried out safely and carefully.

It is important that a beaker is duly labelled and used to collect the waste. The target should always be to keep the volume of waste solution at the barest minimum. This is done by using a very little amount of water in processes that generate waste solutions.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
