The international scientific units of measurements
<h3>
Explanation:</h3>
- SI units are units of measurement that are accepted and agreed upon globally as standard units of measurements.
- Examples include, meters(m) to measure length, kilograms(kg) to measure mass and seconds(s) to measure time among others.
- SI units can however, be converted to other units using multiplication factors. For example to convert kg to g we multiply the number of kg with 1000.
Answer:
Newer
Explanation:
older fossils and rocks are found in lower strata than younger fossils and rock layers because the top layer fossils have not been there as long as the bottom layer fossils to be found deeper in the ground
a) Ka for benzoic acid, C6H5CO2H <span>
HA + H2O ⇋ A^-
+ H3O^+ </span><span>
Ka = [A^-][H3O^+] / [HA]
C6H5CO2H + H2O ⇋
C6H5CO2^-^- + H3O^+ </span><span>
Ka = [C6H5CO2^-][H3O^+] / [C6H5CO2H] </span>
<span>
b) Kb for benzoate ion, (C6H3CO2)^ -
B + H2O ⇋
[BH]^+ + OH^- </span><span>
Kb = [[BH]^+][OH^-] / [B]
C6H3CO2^- + H2O ⇋
C6H5CO2H + OH^- </span><span>
Kb = [C6H5CO2H][OH^-] / [C6H3CO2^-] </span>
<span>
c) Kb for amiline, C6H5NH2 amiline? aniline
C6H5NH2 + H2O ⇋
[C6H5NH3]^+ + OH^- </span><span>
Kb = [[C6H5NH3]^+][OH^-] / [C6H5NH2] </span>
<span>
d)Ka for amilimium ion, (C6H5NH3)^+
C6H5NH3^+ + H2O ⇋
C6H5NH2 + H3O^+ </span><span>
<span>Ka = [C6H5NH2][H3O^+] / [C6H5NH3^+]</span></span>
