Question

A school conducts three exams namely 1st term exam, 2nd term exam and 3rd term exams. Final marks scored (weighted marks) are computed as 20% of 1st term and 2nd term and 60% of the 3rd term marks. Write a program to compute the weighted marks for a student who scored 450 in 1st term, 420 in 2nd term and 480 in 3rd term. Compute the weighted percentage out of 500 marks fund the sample output ​

Answer 1

Answer:

Acetic acid is first converted to its calcium salt by neutralising it with quick lime.

Acetic acid is first converted to its calcium salt by neutralising it with quick lime.2CH3COOH + CaO = Ca(CH3COO)2 + H2O

Acetic acid is first converted to its calcium salt by neutralising it with quick lime.2CH3COOH + CaO = Ca(CH3COO)2 + H2OSolid (pure) calcium acetate on dry distillation yields acetone by decomposition.

Acetic acid is first converted to its calcium salt by neutralising it with quick lime.2CH3COOH + CaO = Ca(CH3COO)2 + H2OSolid (pure) calcium acetate on dry distillation yields acetone by decomposition.Ca(CH3COO)2 = CH3COCH3 + CaCO3

Acetic acid is first converted to its calcium salt by neutralising it with quick lime.2CH3COOH + CaO = Ca(CH3COO)2 + H2OSolid (pure) calcium acetate on dry distillation yields acetone by decomposition.Ca(CH3COO)2 = CH3COCH3 + CaCO3Acetone is usually prepared in the laboratory by the dry distillation of calcium acetate.
