The dissociation of butanoic acid in water gives CH3CH2CH2COO^- and H+
This is according to the following equation
CH3CH2CH2COOH + H2O --->CH3CH2CH2COO^- + H^+
Caesium
and

Answer:
397782000 m²
Explanation:
Given data:
123000 m × 3234 m =?
Solution:
123000 m × 3234 m = 397782000 m²
when we multiply the given quantities having same unit i.e meter the answer should be m² . It could be the area, and its unit is m².
Area = length (m) × width (m)
Answer: B. Elements are represented by chemical formulas.
Elements are pure substances, which means that they cannot be broken down into simpler substances. The element is the most basic substance that exists, breaking it down further means breaking it down into protons, neutrons, and electrons, which is no longer a substance.
Elements have chemical properties that allow them to form different types of bonds with other elements.
However, elements *alone* are not represented by their chemical formulas. Only chemical bonds or ions are represented by a chemical formula.
