Answer:Beryllium is a silvery-white metal.
Explanation:
The production of
is
. Converting mass into kg,
1 ton=907.185 kg, thus,

Thus, production of
will be
.
The specific volume of
is
.
Volume of
produced per day can be calculated as:

Putting the values,

Thus, volume of
produced per year will be:

Thus, in 4 year volume of
produced will be:

The agar plate with the most countable colonies should be determined by using a colony forming unit (CFU) calculator.
<h3>What is a colony?</h3>
A colony can be defined as a group of visible mass of microorganisms such as bacteria, fungi, that originated (cultured) from a single-mother cell and are grown on a solid agar medium.
In order to determine the most countable colonies, we have to count the total number of colonies by using a hemacytometer and then use a colony forming unit (CFU) calculator to determine the cfu/mL.
<u>Note:</u> You should choose a dilution factor based on the total number of colonies contained in the agar plate.
Finally, input the correct dilution factor into the colony forming unit (CFU) calculator to determine which agar plate has the most countable colonies.

Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance. - Google
