The correct option is B. The alkali metals combine directly with halogens forming high melting point crystalline solids that have high negative enthalpies of formation. The entalphy of formation for lithium bromide is the highest and the values decrease down the group, thus, lithium is the most stable while cesium is the least stable.
pH=2.7
<h3>Further explanation</h3>
Acetic acid = weak acid
Ka = acid ionization constant
M = molarity
Ka for Acetic acid(CH₃COOH) : 1.8 x 10⁻⁵
Answer: formic acid
Explanation:
HCOOH is the structural formula for the compound commonly known as formic acid.
According to the international union of pure applied chemist (IUPAC), it is named methanoic acid, and represent the first member of the alkanoic acids.
Thus, examples of alkanoic acids are
- formic acid (HCOOH)
- Acetic acid (CH3COOH)
- Propanoic acid (CH3CH2COOH) etc
Answer:well it should stay the same since nothing was taken away or
Moved. When it comes to liquids, only the property of shape can change unless you physically take away or add some.
