They can both be derived from fossil fuels, biomass, or perhaps from carbon dioxide water.
Answer:
aldehyde and wittig reagent
Explanation:
Alkenes are the organic compounds with at least one c=c. They are homologous series with the general molecular formula of CnH2n.
The symbol R in the uploaded file is an alkyl, which has general formula of CnH2n+1.
Wittig reagent contains Phosphine with phosphorus and an oxygen atom the number (n) in the alkyl groups determines the number of carbon atoms in the resulting alkene.

Answer:
The minimum molecular weight of the enzyme is 29.82 g/mol
Explanation:
<u>Step 1:</u> Given data
The volume of the solution = 10 ml = 10*10^-3L
Molarity of the solution = 1.3 mg/ml
moles of AgNO3 added = 0.436 µmol = 0.436 * 10^-3 mmol
<u>Step 2:</u> Calculate the mass
Density = mass/ volume
1.3mg/mL = mass/ 10.0 mL
mass = 1.3mg/mL *10.0 mL = 13mg
<u>Step 3:</u> Calculate minimum molecular weight
Molecular weight = mass of the enzyme / number of moles
Molecular weight of the enzyme = 13mg/ 0.436 * 10^-3 mmol
Molecular weight = 29.82 g/mole
The minimum molecular weight of the enzyme is 29.82 g/mol
