Answer:
Gamma ray
Explanation:
Radio waves have low energy photons, microwave photons have a little more energy than the radio waves, infrared photons have more energy than the microwave, then visible, ultraviolet, X-rays, and, the most energetic of all is the gamma-rays
Answer:
2764.11 grams of potassium carbonate
Explanation:
brainliest?
Answer:
2.32 m
Explanation:
So, according to definition of mole fraction:

Mole fraction = 0.176
Applying values as:


So,



Also, Molar mass of toluene = 92.14 g/mol
Thus,
The formula for the calculation of moles is shown below:


Also, 1 g = 0.001 kg
So,

Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,

<u>Molality of benzene = 2.32 m</u>
The result of the procedure is that the copper strip should go through oxidation.
<h3>How to explain the procedure?</h3>
The copper strip should be considered as the anode and the nail should be considered as the cathode.
The anode is the electrode of an electrochemical cell at which oxidation occurs. The anode should be + while the cathode should be negative. Both should be placed in the tank that should be filled with the electrolyte solution.
