Compare and contrast chemical reactions and nuclear reactions in terms of particles involved . Select all the statements that ap
ply Both chemical and nuclear equations are written with equal signs. Nuclear reactions create a difference in the number of protons, neutrons, and electrons after the reaction. A chemical reaction is the rearranging of atoms to form new substances. E=mc^ aleph 2 applies to both chemical and nuclear reactions. In a nuclear reactionparticles can transmute into others. Chemical reactions produce energy on levels comparable to nuclear reactions The total number of protons, neutrons, and electrons stay the same throughout the chemical reaction.

Answer:
is time required to heat to boiling point form initial temperature.
Explanation:
Given:
initial temperature of water,
time taken to vapourize half a liter of water,
desity of water,
So, the givne mass of water,
enthalpy of vaporization of water,
specific heat of water,
Amount of heat required to raise the temperature of given water mass to 100°C:
Now the amount of heat required to vaporize 0.5 kg of water:
where:
mass of water vaporized due to boiling
Now the power rating of the boiler:
Now the time required to heat to boiling point form initial temperature:
