Calculate δgrxn for this equation, rounding your answer to the nearest whole number. caco3(s) → cao(s) + co2(g) δgf, caco3 = −1,128.76 kj/mol δgf, cao = −604.17 kj/mol δgf, co2 = −394.4 kj/mol

for the given reaction is 130.19kJ/mol

Explanation:

To Calculate the , we use the formula:

For the given chemical reaction:

We are given:

Now, to calculate , we put the values in the above equation:

As, the value of comes out to be positive, the reaction is said to be non-spontaneous reaction.

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.
