Consider four beakers labeled A, B, C, and D, each containing an aqueous solution and a solid piece of metal. Identity the beakers m which a chemical reaction will occur and those in which no reaction will occur. a. Mn(s) + Ca(NO3)2(aq) b. KOH(aq) + Fe(s) c. Pt(NO3)2(aq) + Cu(s)d. Cr(s) + H2SO4(aq)Drag each item to the correct bin. Consider the following data for five hypothetical element: Q, W, X, Y, and Z. Rank the elements from most reactive to least reactive. Place the element symbol from most to least reactive. To rank items as equivalent, overlap them. Use the following reactions to arrange the elements A, B, C, and D in order of their rodox reactivity from most reactive to least reactive. A + D+ rightarrow A+ + D C+ + D rightarrow C + D+ B+ + D rightarrow B + D+ B + C+ rightarrow B+ + C Rank from most reactive to least reactive. To rank items as equivalent overlap them.

How much would the freezing point of water decrease if 4 mol of sugar were added to 1 kg of water(k=1.86 c/mol/kg for water and i=1 for sugar

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
