Answer:
2-naphtol is a weak acid and benzoic acid is a stronger acid. NaHCO3 is a weak base, that will only react with a strong acid like benzoic acid. 2-napthol is not soluble in sodium bicarbonate.
Explanation:
2-naphtol is a phenol. Phenol is made of a benzene attached to an OH group. So, it is a (big) organic molecule, and a little non-polar group. The conjugated (or non-localised) electrons in the benzene ring pull electrons away from the OH group. It makes it harder for the oxygen to steal the hydrogen's electrons and become O-.
A phenol is acidic in nature because of this H+ releasing. This will result in forming a phenoxide.
Benzoic acid is a carboxylic acid and is more acidic than a phenol. Since it's acid it will also release H+ ion, in this case to form carboxylate which is more stable than phenoxide. The phenoxide is resonance stabilised.
The negative charge , in carboxylate, is delecoalised on the negatively charged O atom what makes it more stable than phenoxide. Compared to carboxylic acid. ( or benzoic acid) phenol ( or 2-naphtol) is a weak acid.
NaHCO3 is a weak base and will only react with a strong acid like carboxylic acid. A naphtol is not strong enough to react with the weak base NaHCO3.
This means 2-naphtol is a weak acid and benzoic acid is a stronger acid. NaHCO3 is a weak base, that will only react with a strong acid like benzoic acid. 2-napthol is not soluble in sodium bicarbonate.
Answer:
THE TEMPERATURE OF THE GAS AT 180 mL IS 957 K
Explanation:
This question follows Charles' law of the theory of gases. it states that the volume of a fixed mass of gas varies directly with the absolute temperature provided the pressure remains constant.
Mathematically, V1 /T1 = V2 /T2
V1 = 60 mL = 60 /1000 L = 0.06 L
T1 = 319 K
V2 = 180 mL = 180 /1000 L = 1.80 L
T2 = ?
Making T2 the subject of the formula, we have;
T2 = V2 * T1 / V1
T2 = 0.180 * 319 / 0.06
T2 = 57. 42 / 0.06
T2 = 957 K
So therefore, the temperature of the gas at a new volume of 180 mL is 957 K
The answer is <em><u>gas</u></em>.
