The unbalanced equation for the reaction between chlorine gas and sodium iodide is shown below.

Balance the equation (enter the smallest integer possible in each box, including the integer "1" when needed) and determine the amount of NaI consumed and the amounts of NaCl and I2 produced when 0.792 mol of Cl2 reacts.

___Cl2 (g) + ___NaI (s) ___NaCl (s) + ___I2 (s)

___mol NaI consumed
___ mol NaCl produced
___mol I2 produced

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
