Fluoride ion is poisonous in relatively low amounts: 0.2 g of F-per 70 kg of body weight can cause death. Nevertheless, in order to prevent tooth decay, F- ions are added to drinking water at a concentration of 1 mg of F- ion per L of water. How many liters of fluoridated drinking water would a 70-kg person have to consume in one day to reach this toxic level? How many kilograms of sodium fluoride would be needed to treat a 8.50x107-gal reservoir?

Chemistry A suspension was prepared by mixing spherical gum grains with a density of 1.206 gcm-3 and a radius of 0.212 μm and water with a density of 0.999 gcm-3 at 15˚C. Since the number of particles determined microscopically at 5 μm and 35 μm heights from the base is 100 and 47, respectively, in the same time, calculate Avagadro's constant (g= 9.8 m s-2, μm= 10-6 m)

Cocaine (C17H21O4N; Figure 2) is a natural substance found in leaves of the coca plant, which have been used for centuries as a local anaesthetic and stimulant. Illegal cocaine arrives in the USA either as the pure compound or as the hydrochloride salt (C17H21O4NHCl). At 25oC, the salt is very soluble in water (2.50 kg/L), but pure cocaine is much less so (1.70 g/L). What is the maximum amount of the salt (in gram) that can dissolve in 50.0 mL of water? When a 25 mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water (in litres) is needed additionally to dissolve the formed pure cocaine? Round your final answer off to two decimal points.

1. Below is a data table from an experiment in which an effervescent tablet is added to a test tube of water, producing a solution that fizzes and releases gas bubbles. The total mass of the substances and the test tube were recorded before and after the tablet was added to the test tube of water. If matter is always conserved, how do you explain these results? Explain in 3-5 sentences.
The mystery fuel speedster! (Homework ) For fun, you build an explosive car with your little brother by attaching wheels to an empty windshield washer container. To advance it, you add 1.20 ml ( = 0.7915 g/ml) of a liquid but volatile fuel into the container. You close the cap and shake to evaporate the liquid. Finally, you place the car on its wheels, remove the cap and insert a burning wooden rod into the container. A flame suddenly comes out of the car, which is propelled with good speed in front of your little brother surprised, but all upset by the maneuver. The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol. During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too. The volume of the windshield washer container used is 4.00 litres. Useful Info: There is 21.0% gaseous oxygen in the air and initial conditions…
