Reactants- acid and alkali (base)
products- water and salt
Answer:
Molecular Formula: C6H11NaO2
Parent Compound: CID 8892 (Hexanoic acid)
Explanation:
When a mixture of 1−hexanol and hexanoic acid in diethyl ether is shaken with an aqueous NaHCO 3 solution, Hexanoic acid will react with NaHCO 3 to form sodium hexanoate.
CH 3 −CH 2 −CH 2 −CH 2 −CH 2−COOH+NaHCO 3→CH 3−(CH 2 ) 4 −COONa+H 2 O+CO 2
Average atomic mass of an element is a sum of the product of the isotope mass and its relative abundance.
For example: Chlorine has 2 isotopes with the following abundances
Cl(35): Atomic mass = 34.9688 amu; Abundance = 75.78%
Cl(37): Atomic mass = 36.9659 amu; Abundance = 24.22 %
Average atomic mass of Cl = 34.9688(0.7578) + 36.9659(0.2422) =
= 26.4993 + 8.9531 = 35.4524 amu
Thus, the term “ average atomic mass “ is a <u>weighted</u> average so it is calculated differently from a normal average
The change in internal energy that accompanies the transfer of heat (q) or work (w), into or out of a system can be calculated using the following equation: Note the value of heat and work as they are transferred into or out of a system.
At 40 degrees Celsius, approximately 78 grams of potassium bromide can be dissolved.
