Answer:
Explanation:
Salicylic Acid:
Salicylic Acid is an hydroxy acid that is found as a natural compound in plants. It's IUPAC name is 2-hydroxybenzoic acid. Salicylic acid has an odorless white to light tan solid color. It sinks and mixes very slow with water.
Acid: An acid is a substance that produce hydrogen ion or proton when dissolved in water
Base: A base is a substance that will neutralize an acid to yield salt and water
Conjugate Base: This is a substance formed when an acid loses an hydrogen ion or proton when it dissolved in water.
Conjugate Acid: This is a substance formed when a base accept a proton from from any acid, when it dissolved in water.
Reaction between salicylic acid and potassium hydroxide
HOC₆H₄COOH(aq) + KOH(aq) ⇄ HOC₆H₄COOK(aq) + H₂O(l)
Acid ⇒ HOC₆H₄COOH (salicylic acid)
Base ⇒ KOH (potassium hydroxide)
Conjugate acid ⇒ H₂O (water)
conjugate base ⇒ HOC₆H₄COOK ( 2-hydroxypotasium benzoate)
Answer:
The reactant/reagent that would be most atom economical is EtI (Ethy Iodide) and KOH (potassium oxide) as base
This is because the iodo group are weak base hence they have a good leaving character (i.e they are unstable on their own ) which would increase the rate of reaction and the strong base KOH give the most atom economical
Explanation:
The hydrogen deficiency index( HDI) of strigol is = 10
<h3>How to calculate HDI:</h3>
The hydrogen deficiency index is used to measure the number of degree of unsaturation of an organic compound.
Strigol is an example of an organic compound because it contains carbons and hydrogen.
To calculate the HDI using the molecular formula given (C19H20O6) the formula for HDI is used which is:

where C = number of carbon atoms = 19
n= number of nitrogen atoms = 0
h= number of hydrogen atoms = 20
X = number of halogen atoms = 0
Note that oxygen was not considered because it forms two bonds and has no impact.
There for HDI =

HDI=

HDI =

HDI = 10
Therefore, the hydrogen deficiency index of strigol is = 10

Answer:
186.9Kelvin
Explanation:
The ideal gas law equation is PV
=
n
R
T
where
P is the pressure of the gas
V is the volume it occupies
n is the number of moles of gas present in the sample
R is the universal gas constant, equal to 0.0821
atm L
/mol K
T is the absolute temperature of the gas
Ensure units of the volume, pressure, and temperature of the gas correspond to R
( the universal gas constant, equal to 0.0821
atm L
/mol K
)
n

3.54moles
P= 1.57
V= 34.6

186.9Kelvin ( approximately to 1 decimal place)
Answer:
14.048 moles I believe.
Explanation:
(8.46 * 10^24) / ( 6.022 * 10^23) = 14.048
