Answer:
Percent yield = 75%
Explanation:
Given data:
Actual yield of ammonia = 60 g
Theoretical yield of ammonia = 80 g
Percent yield = ?
Solution:
Percent yield is calculated dividing the actual yield by theoretical yield and multiply by 100.
Formula:
Percent yield = Actual yield / Theoretical yield × 100
Now we will put the values in formula.
Percent yield = 60 g/ 80 g × 100
Percent yield = 0.75 × 100
Percent yield = 75%
So if the reaction yield is 60 g and calculated yield ( theoretical yield) is 80 g then the percent yield would be 75%.
Answer:
option C= hydrolysis and break down
Explanation:
All other three pairs are correct coupling of each others.
Option A= dehydration synthesis and hydrolysis
Dehydration synthesis:
In dehydration synthesis monomers combine through the covalent bonds and form large molecules. The large molecules are called polymers. The water as a byproduct also released when monomers joints together.
Hydrolysis:
In hydrolysis the polymers are break down into monomers by using water molecules. The catalysts are also required in this process.
Option B= Catabolic and Anabolic
Anabolic:
In this process smaller molecules combine to gather to form large complex molecules by using energy.
For example simple glucose molecules join together to form large disaccharides.
Catabolic:
It is the break down of large complex molecules to the smaller molecules.
For example during cellular respiration sugar molecules break down and generate energy.
Option D= Break down and synthesis
The break down and synthesis are also reverse pair of each others. The synthesis involve the formation of molecules form smaller component while the break down involve destruction of molecules into smaller units.
Answer:
Yes, chloromethane has stronger intermolecular forces than a pure sample of methane has.
Explanation:
In both methane and chloromethane, there are weak dispersion forces. However, in methane, the dispersion forces are the only intermolecular forces present. Also, the lower molar mass of methane means that it has a lower degree of dispersion forces.
For chloromethane, there is in addition to dispersion forces, dipole-dipole interaction arising from the polar C-Cl bond in the molecule. Also the molar mass of chloromethane is greater than that of methane implying a greater magnitude of dispersion forces in operation.
Therefore, chloromethane has stronger intermolecular forces than a pure sample of methane has.
Answer:
mining of clay limestone and then heated to a certain temperature of 1450⁰ in a cement kiln
When particles collide, they transfer fro their thermal energy.
Hope this helps.
