The reaction between calcium carbonate (CaCO3) and HCl produces calcium chloride (CaCl), carbon dioxide (CO2), and water (H20) What happens when the concentration of hydrogen chloride (HCl) molecules is doubled in this reaction?

CaCo3 + 2HCl - CaCl2 + CO2 + H20

, which causes

When the hydrogen chloride concentration doubles, the number of collisions between the reactants

the rate of the forward reaction to

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
