Explanation:
Glycogen is the form that glucose is stored in human body.
Cellulose is the structural part of plant cell walls and human cannot digest it.
Amylose is the polysaccharide linked mainly by the the bonds of 1,4 glycosidic.
Cellulose is an unbranched polysaccharide linked mainly by the bonds of 1,4 glycosidic.
Amylopetin and Glycogen are branched polysaccharides linked by the bonds of 1,4 glycosidic and
1,6 glycosidic.
Amylopetin and Cellulose are mainly stored in plants.
Answer : The final volume of gas is, 11.5 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 2.30 atm
= final pressure of gas = 5.40 atm
= initial volume of gas = 20.0 L
= final volume of gas = ?
= initial temperature of gas = 308 K
= final temperature of gas = 416 K
Now put all the given values in the above equation, we get:
Therefore, the final volume of gas is, 11.5 L
