Most probably copper chloride and carbon dioxide, if the concentration of hydrochloric acid is high enough.
copper sulphate and carbon dioxide
hydroplasm
When copper carbonate is mixed with hydrochloric acid, a chemical reaction occurs which produces copper chloride, carbon dioxide gas, and water. The copper carbonate will dissolve and react with the hydrochloric acid to form a blue-green solution. The carbon dioxide gas bubbles out of the solution, creating fizzing or effervescence.
No reaction between them
Any acid will react with any carbonate to produce carbon dioxide and water. The other product is an ionic compound of the remaining ions, in this case copper chloride. (If the problem requires you to include phase labels, you also have to decide whether the ionic product will be soluble in water or not.)
Yea
You can separate sand and copper carbonate by using a process called filtration. First, mix the sand and copper carbonate in water to form a mixture. Then, pour the mixture through a filter paper in a funnel. The sand will be trapped on the filter paper while the copper carbonate will pass through as a liquid.

Carbon Dioxide, CO2.
bismuth iodide
Copper(s)
The salt formed when carbonic acid and aluminum hydroxide mix is aluminum carbonate. This reaction occurs when the acid-base reaction between carbonic acid and aluminum hydroxide takes place, resulting in the formation of aluminum carbonate salt.
