12.18 u
Explanation:
The average atomic mass of an element is calculated by taking the weighted average of the atomic masses of its stable isotopes.
Answer:
3) ester
Explanation:
Esterification is the process in which alkanol and alkanoic acids reacts in the presence of a catalyst and heat. The product is usually an ester(alkanoate) and water.
For the reaction between ethanoic acid and 1-butanol, the product is butylethanoate and water as shown below:
CH₃COOH + C₄H₈OH → CH₃COOC₄H₈ + H₂O
I believe that The answer is
Since power, P, equals iV, P/V = i, so at 120 V, a 40-watt bulb draws 1/3 A.
The answer is -ate:
If there are two similar, oxygen-containing ions, the ion with more oxygen atoms ends in -ate.
