6. Fertilizer is sold in 100 pound bags labelled with the amount of nitrogen ( N), phosphoric acid ( P205), and potash ( K20) present. The mixtureof these nutrients varies from one type of fertilizer to the next.For example, a 100 pound bag of Vigoro Ultra Turf fertilizer contains 29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds ofpotash.Another type of fertilizer, Parker's Premium Starter, has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per 100pounds.Determine the amount of each type required to yield a mixture containing the 101 pounds of nitrogen, 103 pounds of phosphoric acid, and 28pounds of potash.The mixture containspounds of Vigoro, andpounds of Parker's.Hint: Let x1 be the amount of 100 pound bags of Vigoro, and x2 the amount of 100 pound bags of Parker. Set up and solve the system in theunknowns x1 and x2 and then multiply the solution by 100 to find the number of pounds. Consider the chemical reactionAC2H6 + 6CO2 +CH2O → ¿C2H;OH,wherea,b, c, and d are unknown positive integers. The reaction must be balanced; that is, the number of atoms of each element must be thesame before and after the reaction. For example, because the number of oxygen atoms must remain the same,2b + с — d.While there are many possible choices for a, b, c, and d that balance the reaction, it is customary to use the smallest possible integers.Balance this reaction.a =b =d =

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?

When Kay added 30g of Hydrochloric acid (HCI) to 65g of Zn, bubbles appeared and a white precipitate, zinc chloride (ZnCl2) was produced. She found that the mass of the zinc chloride was 93g. Since the law of conservation of matter stated that matter can’t be created or destroyed, she was puzzled about the difference in mass. What is the best explanation for the missing 2g?
