Question

The copper was not completely dry before weighing. c. Predict whether the following reactions will occur or not. For those that do occur complete and balance the equation. Write "No Reaction" for those that do not occur. Include all subscripts (s), (aq), etc.). 2. (ag) 3. What is the molarity of a silver() nitrate solution if 50.00 mL of the silver) nitrate solution is reacted with magnesium, producing 3.580 g of dry silver metal Include the balanced molecular equation in the space provided. Balanced Molecular Equation:

Explanation / Answer

2) Mn(s) + SnCl2(aq) --------> MnCl2(aq) + Sn(s)

Cr(s) + 2HBr(aq) ------> CrBr2(aq) + H2(g)

Co(s) + CaBr2(aq) -------> No reaction

2Al(s) + 3Ni(NO3)2(aq) ----------> 2Al(NO3)3(aq) + 3Ni(s)

3)

2AgNO3(aq) + Mg(s) -----> 2Ag(s) + Mg(NO3)2(aq)

mass of Silver = 3.580g

Molar mass of Ag = 107.87g/mol

No of mole of Ag = 3.580g/107.87g/mol = 0.03319

0.03319mole of Ag represents 0.03319mole of AgNO3

Volume of AgNO3 solution = 50ml

Molarity of Silver(I)Nitrate solution = (0.03319mol/50ml)×1000ml =0.6638M
