We are asked for the energy emitted by a photon using the wavelength given. In this case, we use the planck relation that correlates energy and wavelength using Planck's constant and speed of light as constant of proportionality. The formula is E = hc / w where h is equal to 6.626 x10-34 Js and c is equal to 3 x10 8 m/s. E then is equal to 1.55 x10-24 J
The nitrogen fixation step is very necessary since it is allows nitrogen to be used by living organism. In this step nitrogen in the atmosphere is being converted into ammonia or other nitrogen compound that can be used by organisms.
Answer:
The correct answer is that both molecular motion, pressure and temperature increase as volume reduces.
Explanation:
A reduction in volume changes the molecular motion, temperature and pressure of the system. When the volume of the container decreases, this causes the pressure to increase, the temperature to increase and the molecular motion to increase. This is because a liquid and a solid are incompressible, so by reducing the volume of a gas, the molecules increase their movement as the temperature of the system increases, which is due to the increased pressure applied to reduce the volume of the system.
Have a nice day!

Answer:
80.0°C will be the final temperature inside the calorimeter.
Explanation:
Heat lost by the pace of jewelry will be equal to heat gained by the another piece of the jewelry
Mass of piece-1= 
Specific heat capacity of copper= 
= 0.387 J/g.K
Initial temperature of the iron = 
Final temperature = 
=T
Mass of piece-2= 
Specific heat capacity of copper = 
= 0.387 J/g.K
Initial temperature of the water = 
Final temperature of water = =T
(conservation of energy)
On substituting all values:
80.0°C will be the final temperature inside the calorimeter.
