The best way (in my opinion) is to put it in a table or spreadsheet.
Answer:
42.82 × 10²³ formula units
Explanation:
Given data:
Number of moles of CaCl₂ = 7.11 mol
Number of formula units = ?
Solution:
We will solve this problem by using Avogadro number.
1 mole of substance contain 6.022× 10²³ formula units.
7.11 mol × 6.022× 10²³ formula units / 1mol
42.82 × 10²³ formula units
Answer : The enthalpy of this reaction is, 0.975 kJ/mol
Explanation :
First we have to calculate the heat produced.
where,
q = heat produced = ?
m = mass of solution = 126 g
c = specific heat capacity of water = 
= initial temperature = 
= final temperature = 
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy of this reaction.
where,
= enthalpy change = ?
q = heat released = 1.95 kJ
n = moles of compound = 2.00 mol
Now put all the given values in the above formula, we get:
Thus, the enthalpy of this reaction is, 0.975 kJ/mol
<u>Urea get decomposed during autoclaving, because it is volatile. It is filter </u><u>sterilized </u><u>and added aseptically to your </u><u>autoclave media.</u>
Can urea be autoclaved?
- Urea get decomposed during autoclaving, because it is volatile.
- It is filter sterilized and added aseptically to your autoclave media.
What is autoclave sterilization?
- In medical and laboratory settings, an autoclave is used to sterilise waste and lab supplies.
- Heat is used in the autoclave sterilisation process to eliminate bacteria and spores. Pressurized steam provides the heat.
What is filter sterilization?
- By using filtering, it is possible to exclude organisms based on their size. There are many different kinds of filtration methods, but membrane filtration is utilised to sterilise a system.
- Contaminants that are larger than the pore size are captured by membrane filtration on the membrane's surface.
