Answer:
Eqv Pt pH = 8.73
Explanation:
HOAc + NaOH => NaOAc + H₂O
50ml(0.10M HOAc) + 50ml(0.10M NaOH) => 100ml(0.05M NaOAc) + H₂O
For neutralized system, 100ml of 0.05M NaOAc remains
NaOAc => Na⁺ + OAc⁻
Na⁺ + H₂O => No Rxn
OAc⁻ + H₂O => HOAc + OH⁻
C(i) 0.05M ----- 0M 0M
ΔC -x ----- +x +x
C(f) 0.05-x
≅ 0.05M ----- x x
Kb = Kw/Ka = [HOAc][OH⁻]/[OAc⁻] = 1 X 10⁻¹⁴/1.7 X 10⁻⁵ = (x)(x)/(0.05M)
=> x = [OH⁻] = SqrRt(0.05 x 10⁻¹⁴/1.7 x 10⁻⁵) = 5.42 x 10⁻⁶M
=> pOH = -log[OH⁻] = -log(5.42 x 10⁻⁶) = 5.27
pH + pOH = 14 => pH = 14 - pOH = 14 - 5.27 = 8.73 Eqv Pt pH
Answer:E
Explanation:
The electron is expected to be in any of the 4p orbitals. For the 4p orbitals
n=4
l=1
ml=-1,0,1
ms=-1/2 or +1/2
All the ml and ms configurations are equiprobable hence the answer.
Answer: The mole percent of 1-methylcyclohexene was 80.21% and the mole percent of 3-methylcyclohexene was 19.79%. This is because 1-methylcyclohexene is the major product with the more stable carbocation intermediate and 3-methylcyclohexene is the minor product with the less stable carbocation intermediate.
Explanation: The mole percent of 1-methylcyclohexene was 80.21% and the mole percent of 3-methylcyclohexene was 19.79%
Water is a chemical used in toothpaste.
Fluoride in the form of sodium fluoride is another chemical.
A response that is chemical in nature and is characterized with the aid of the release of power in the shape of warmth or light is referred to as an exothermic response.
Following processes are exothermic:-
freezing of water.
digestion of food.
a person running.
heating with a furnace.
Following processes are endothermic:-
boiling of water.
a person growing.
wood being chopped.
Endothermic reactions are chemical reactions wherein the reactants soak up warmness electricity from the environment to shape products. those reactions decrease the temperature of their surrounding place, thereby growing a cooling impact.
DISCLAIMER:- Your question is incomplete , see full question below:-
Classify the following processes as exothermic or endothermic:
(a) freezing of water.
(b) boiling of water.
(c) digestion of food.
(d) a person running.
(e) a person growing.
(f) wood being chopped.
(g) heating with a furnace.
