Answer:
Benzoic acid is the stronger acid
Explanation:
Weak acids do not dissociate completely in the solution. They exists in equilibrium with their respective ions in the solution.
The extent of dissociation of the acid furnising hydrogen ions can be determined by using dissociation constant of acid ().
Thus for a weak acid, HA
The is:
The more the , the more the acid dissociates, the more the stronger is the acid.
Also,
is defined as the negative logarithm of .
So, more the , less is the and vice versa
All can be summed up as:
The less the value of , the more the is and the more the acid dissociates and the more the stronger is the acid.
Given,
of acetic acid = 54.7
of benzoic acid = 54.2
of benzoic acid < of acetic acid
So, benzoic acid is the stronger acid.
Answer:
The correct answer is option 3. Run a test reaction of crude oil with ocean water over time with Oil Spill Eater present
Explanation:
In any laboratory experiment, all the apparatus needed to carry out a particular experiment must be provided. In this case, our apparatus will be crude oil with ocean water and oil spill eater which is the enzyme used.
We can then run a test reaction of crude oil with ocean water over time with Oil Spill Eater present.
<u>Answer:</u> The frequency of the radiation is 33.9 THz
<u>Explanation:</u>
We are given:
Wave number of the radiation,
Wave number is defined as the number of wavelengths per unit length.
Mathematically,
where,
= wave number =
= wavelength of the radiation = ?
Putting values in above equation, we get:
Converting this into meters, we use the conversion factor:
1 m = 100 cm
So,
- The relation between frequency and wavelength is given as:
where,
c = the speed of light =
= frequency of the radiation = ?
Putting values in above equation, we get:
Converting this into tera Hertz, we use the conversion factor:
So,
Hence, the frequency of the radiation is 33.9 THz
