Answer : The number of moles of air present is, 0.055 mole

Solution :

Using ideal gas equation :

PV=nRT

where,

P = pressure of the gas = 750 torr = 0.98 atm      (1 atm = 760 torr)

V = volume of the gas = 1.35 L

T = temperature of the gas = 17^oC=17+273=290K

R = gas constant = 0.0821 Latm/moleK

n = number of moles of air = ?

Now put all the given values in this formula, we get the number of moles of air present.

(0.98atm)\times (1.35L)=n\times (0.0821Latm/moleK)\times (290K)

n=0.055mole

Therefore, the number of moles of air present is, 0.055 mole

Which of the following could result from having few or no ?-1,6 linkages in glycogen? Select all that apply.
Katen [24]

Answer:

The correct answer is 1 glycogen degradation would slow down.

Explanation:

Glycogen is the principle storage polysaccharide present in the liver and muscle of human body.

    Glycogen contain both alpha-1,4-glycosidic linkage and alpha -1,6-glycosidic linkage.During glycogenolysis some glucose residues are transferred from branch point of the glycogen to its end and thereafter a single glucose residue is linked to the branch point of glycogen by alpha-1,6-glycosidic linkage.

   The alpha-1,6-glycosidic linked glucose of glycogen is finally get separated from glycogen by the catalytic activity of alpha-1,6-glycosidase enzyme in the final step of glycogenolysis.

 According to the given question if there is no alpha-1,6-glycosidic linkage in the glycogen then glycogen degradation will slow down.

Which of the following situations contains an example of a chemical reaction?
bogdanovich [222]

A bicycle rusting after it is left in the rain is an example of a chemical reaction because it involves oxidation (Option d).  

<h3>What is a chemical reaction?</h3>

A chemical reaction can be defined as a phenomenon in which one or more substances called reactants react to form one or more different compounds, which are known as products.

A chemical reaction may include an enzyme that works to increase the seed of the reaction in normal conditions by lowering the activation energy of the reaction.

Therefore, we can conclude that a chemical reaction such as oxidation in a bicycle is a process where reactants combine or break down to form the products of such reaction.

Complete question:

Which of the following situations contains an example of a chemical reaction?

a. Ice forming after water is placed in a freezer

b. Watercolor paint drying on paper

c. a sugar cube dissolving in a glass of water

d. a bicycle rusting after it is left in the rain
