Nimfa-mama [501]

The enthalpy energy in condensation process is negative because it releases energy
The entropy in will also decreases .
Temperature affected this change because it will now create free energy if added with this result this is the condestion process

What is the energy in joules of one photon of microwaveradiation with a wavelength 0.122m?

pentagon [3]

Answer: The energy of photon is $162.93\times 10^{-26}J$

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

$E=\frac{hc}{\lambda}$

where,

E = energy of the light = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

c = speed of light = $3\times 10^8m/s$

$\lambda$ = wavelength of photon = 0.122 m

Putting values in above equation, we get:

$E=\frac{(6.626\times 10^{-34}Js)\times (3\times 10^8m/s)}{0.122m}\\\\E=162.93\times 10^{-26}J$

Hence, the energy of photon is $162.93\times 10^{-26}J$

What is the molarity of a solution in which 25g NaCl in a 2.00 L solution?

Paladinen [302]

Mass of sodium :- 23 grams

Mass of Chlorine :- 35.5 grams

Mass of NaCl :- 58.5 grams

mass given :- 25 grams

moles :- 0.432 ( given mass/ ionic mass)

$molarity = \frac{moles}{vol} \\ molarity = \frac{0.432}{2} \\ molarity = 0.216 \: mole{l}^{ - 1} or \: molar$

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.

almond37 [142]

True

Explanation:

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.

This very correct.

When electricity is used in a sustainable way, there is little of it consumed.
Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
Less coal and fuel would be used and power plants do not need to produce as much electricity.
Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
When these appliances are turned off, less energy is in demand and less will be produced.
