Hey guys, i just have some quick questions I'm having trouble with. I'm in a hurry right now so i'll come back tommorow and type up what I was thinking about them, here are the questions.
1) Farmers use ferilizers mainly to replace depleted nutrients in the soil. Liquid ammnia and ammonium nitrate are two substances that are used to replace essential nitrogen in the soul. Based on the percentage of nitrogen by mass, which of these two chemicals would be the better fertilizer? Assume that the cost per kilogram of each chemical is about the same.
2)a) How many grams of sulphuric acid will neutralize 10.0 g of sodium hydroxide?
b) What volume of water vapour at 100C and 110 kPa would also be produced?
3) An industrial plant that specializes in cleaning up waste liquids is confronted with a problem of separating the metal ions found in the large vat of solution. By analysis, the solution was found to contain varying quantities of silver, barium, and iron(III) ions. Suggest a procedure for separating the metal ions by precipitation.
Thanks in advance for anyone that is willing to help.
