When hydrochloric acid and zinc were combined, the salt zinc chloride and hydroge gas are being produced in the flask. The flask was said to be sealed and, therefore, no gas could escape from the flask. As the temperature decreases, the pressure inside would decrease since the gas would have lower kinetic energy and would have less force to exert on the walls of the flask. This is also evident from the equation PV = nRT. As we can see pressure and temperature are directly related which means as one decreases, the other decreases as well or as one increases, the other would increase accordingly.
Potassium should have largest atomic radius.......
'cause on moving to right, attractive force between nucleus and electrons increases and causes shielding effect, due to which atomic radius get smaller
Volt is the unit to measure cell potential.
Explanation:
The cell potential is the measure of potential difference in the two halves of the electrochemical cell.
It is the measure of how much voltage exists between the two halves of the battery. The unit of volt is joule/coulomb. The cell potential is measured by voltmeter.
The energy per unit charge from the oxidation-reduction reaction to drive the reaction is cell potential.
