I am answering A question
Answer:
ions need to be present in the water. If there are no ions in solution, no electricity is conducted. since, in water, electricity is conducted, this means that HCl completely ionizes to H + and C l − ions. However, in chloroform, since there is no conduction, HCl does not ionize and stays as the
Explanation:
B. The number of collisions with enough energy to react increases.
The increase in temperature increases the average kinetic energy, so more collisions have enough energy to overcome the activation energy barrier.
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>
