The useful metal manganese can be extracted from the mineral rhodochrosite by a two-step process. In the first step, manganese(II) carbonate and oxygen react to form manganese(IV) oxide and carbon dioxide: 2 MNCO,(s) + 0,(g) → 2 MnO,(s) + 2 CO,(g) In the second step, manganese(IV) oxide and aluminum react to form manganese and aluminum oxidide: 3 MnO,(s) + 4 Al(s) → 3 Mn(s) + 2 Al,0(s) Suppose the yield of the first step is 70.% and the yield of the second step is 82.%. Calculate the mass of manganese(II) carbonate required to make 4.0 kg of manganese. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

4. A student does a reaction that forms Pb(NO3)2 (ag). The student boils off some of the water in a beaker until Pb(NO3)2 (s) crystals form. The student vacuum filters this solution to collect the crystals. Since some of the crystals remain in the beaker, the student squirts water from their wash bottle in the beaker and pours this over the filter paper in the vacuum apparatus. When the student goes to collect the crystals from the paper they find that there is none there. Explair what happened and how it can be corrected.

In a lab, a grade 11 chemistry student used 0.0123 mol of solid magnesium metal. The student proceeds to burn the magnesium metal in a Bunsen burned with an excess amount of oxygen gas to produce 0.41g of magnesium oxide based on the following balanced equation: 2Mg(s) + 02(g) —> 2MgO(s). The theoretical amount of magnesium oxide should be what?
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.Suppose an EPA chemist tests a 250.mL sample of groundwater known to be contaminated with cadmium chloride, which would react with silver nitrate solution like this: CdCl2(aq)+2AgNO3(aq)→2AgCl(s)+CdNO32(aq). The chemist adds 51.0mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 8.9mg of silver chloride. Calculate the concentration of cadmium chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits.
