Be sure to answer all parts. write a balanced equation and kb expression for the following brønsted-lowry base in water: benzoate ion, c6h5coo−. include the states of all reactants and products in your equation. you do not need to include states in the equilibrium expression. balanced equation: ⇌ kb expression:

The balanced reaction is:-

expression is:-

Explanation:

Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-

The expression for dissociation constant of benzoate ion is:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
