Answer:
206 kj of heat is required to boil 78.5 kg of water at its boiling point
The role of conservation of linear momentum is important to your safety as a pedestrian or a motorist because you will avoid being hit by car.
<h3>
Conservation of linear momentum</h3>
The principle of conservation of linear momentum states that the sum of the initial momentum of an isolated system is equal to the sum of the final momentum.
The role of conservation of linear momentum is important to your safety as a pedestrian or a motorist because you will avoid being hit by car which is in motion, knowing that impulse you will receive will be equal to the change in the momentum of the car.

Answer:
Like Earth, it gets plenty of sunlight. We don’t see the far side because “the moon is tidally locked to the Earth,” said John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project. “The moon does rotate, but it rotates at the same speed that it rotates around the Earth.”

Answer:
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
Explanation:
,ΔH = 242.8 kJ/mol
Energy required to break 1 mole of Cl-Cl bond = 242.8 kJ
Energy required to break 1 Cl-Cl bond = E
Energy related with the wavelength of light is given by Planck's equation:
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
