Answer:
62.50
Explanation:
I divided the 125 in the result is 62.50 but it is considered a 62.
never mine:)
Answer:
1.7700×10^-22 g
Explanation:
A face-centered-cubic cell contains 4 atoms, so the volume per atom is ...
(389.80×10^-12 m)³/(4 atoms) ≈ 1.4725×10^-29 m³
Then the mass of 1 atom is ...
(12020 kg/m³)(1.4725×10^-29 m³) ≈ 1.76995×10^-25 kg
≈ 1.7700×10^-22 g
_____
<em>Additional comment</em>
That is the approximate mass of a Palladium atom.
The coins in 1991 had more copper in them compared to the coins today. So, that is why it worth 3.3p.
The medium that might be used to cool the hot liquid coming from a reactor is : ( C ) Heat exchanger
<h3>Function of the heat exchanger</h3>
Heat exchanger is used for the transfer of heat between liquids to be used in a chemical reaction, It can be used for both Cooling and heating to achieve the desired temperature.
The liquid coming from a reactor which posses a very high temperature will be passed through the heat exchanger so that its temperature will attain the required temperature for the experiment.
Hence we can conclude that The medium that might be used to cool the hot liquid coming from a reactor is Heat exchanger.
