How much would the temperature (in °C) of 268 g of water at 25°C increase if 33.8 kJ of heat were added?

beta decay is the answer

did anyone actually do this? like if anyone has submitted this i rly need .

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
