Answer:
Kc of the reaction is 0.9375
Explanation:
Step 1: Data given
Moles of SO2 = 0.40 moles
Moles of O2 = 0.60 moles
Volume = 1.00 L
After the reactio we find 0.30 moles SO3
Step 2: The balanced equation
2 SO2(g) + O2(g) ⇔ 2SO3(g)
Step 3: Calculate Kc
Kc = [SO3]² / ([SO2]²[O2])
Kc = 0.30² / (0.40²*0.60)
Kc = 0.9375
Kc of the reaction is 0.9375
Solution : Water and Methanol are easily miscible in any amount. so they are not preferred for the liquid-liquid extraction process.
Liquid-Liquid Extraction is also called as solvent extraction. It is the method of seperation of compound based on their relative solubilities in two different immiscible liquids. Generally we use water (polar) and an organic solvent (non-polar).
It is important that the two solvents should not be mix because it is easy to seperate them.
Water and Methanol are easily miscible in any amount. we can not seperate them easily. So that is why we can not use water and methanol as a solvent in liquid-liquid extraction process.
Answer:
A is the answer
Explanation:
See, let me explain it first of all.
Because, We all know every drop of water is being evaporated from the seas, streams, oceans,etc. So, the statement is wrong about it. It is wrong. How can't water get evaporated from the seas and the streams,etc.

Answer:
Denaturation causes loss of enzyme activity which is necessary for biochemical reaction.
Hence many biological process(respiration,digestion,excretion) won't work properly.
Explanation:
Enzymes : These are biological catalyst made of proteins.E.g Pepsin, tyrosine (human digestion)
Denaturation: loss of Quaternary ,tertiary and secondary structure of proteins and nucleic acid because of extreme conditions of temperature , pressure ,pH etc.
When denaturation occur enzymes loss their specific structure, so they can't carry out various life process (e.g respiration, digestion ,excretion).
Enzymes are involved in all biological reaction and work only at optimum temperature ,pH and pressure(human body condition ).
