Rico is doing an experiment. He makes a solution of calcium carbonate in a beaker of 200
mL of water at room temperature (25 °C). He adds a small amount of lemon juice to the
solution and a chemical reaction begins. Rico reduces the temperature of the solution by
10 °C by adding ice. As the solution cools, what will happen to the chemical reaction?
The chemical reaction will stop suddenly.
There will no change in the rate of the chemical reaction.
The chemical reaction will slow as the water cools.
The speed of the chemical reaction will increase as the water cools.

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.
