2. To mix an ultrasonic cleaning solution, 10 milliliters (mL) of concentrated cleaner is added to 500 mL of distilled water. What is the ratio of cleaner to

water?

of 10

ratio of cleaner to water = 1 : 50

Explanation:

volume of ultrasonic cleaning solution = 10 mL

volume of distilled water = 500 mL

∴ ratio of cleaner to water = 10 : 500

simplifying further

10 : 500 = 1 : 50

∴ ratio of cleaner to water = 1 : 50

answer; the above is a (true) statement;

                                                        water

a colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

                                                        halon  

any of a number of unreactive gaseous compounds of carbon with bromine and other halogens, used in fire extinguishers, but now known to damage the ozone layer.

                                                  dry chemical

extinguishing agent used on class a, class b, and class c fires.

                                                  carbon dioxide

a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. it is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
