Answer:
D. Sulfonation
Explanation:
Electrophilic aromatic substitution -
The subsitution reaction , where the hydrogen atom of an aromatic ring is replaced by an external electrophile .
Sulfonation reaction -
The subsitution reaction , where the hydrogen atom of an aromatic ring ( benzene) is replaced by an sulfonyl group , is called an Sulfonation reaction .
The Sulfonation reaction is reversible in nature , because , heating of aqueous sulfuric acid with sulfonic acid , can lead to a reverse reaction , i.e. , desulfonation .
The specific heat capacity of liquid water is 4.186 J/gm K. This means that each gram of liquid water requires 4.186 Joules of heat energy to raise its temperature by one degree Kelvin. One molar mass of water is equivalent to 18 grams. Therefore, the molar heat capacity becomes the product of 4.186 and 18
Answer:
1 g/cm3
Explanation:
The formula for density is mass/volume
The mass is 100 g and the volume is 100 cm3
100 g/100 cm3=1 g/cm3
Oxidation number of Cl in chlorate ion ClO3- is +5
Answer:
1750L
Explanation:
Given
Initial Temperature = 25°C
Initial Pressure = 175 atm
Initial Volume = 10.0L
Final Temperature = 25°C
Final Pressure = 1 atm
Final Volume = ?
This question is an illustration of ideal gas law.
From the given parameters, the initial temperature and final temperature are the same; this implies that the system has a constant temperature.
As such, we'll make use of Boyle's Law to solve this;
Boyle's Law States that:
P₁V₁ = P₂V₂
Where P₁ and P₂ represent Initial and Final Pressure, respectively
While V₁ and V₂ represent Initial and final volume
The equation becomes
175 atm * 10L = 1 atm * V₂
1750 atm L = 1 atm * V₂
1750 L = V₂
Hence, the final volume that can be stored is 1750L
