Answer:

A bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution.

Explanation:

First, recall that:

Molarity of a substance = no of moles of the substance/volume of the solution in liters.

In this case, the number of moles of hydrogen peroxide is 0.95 mole while the volume of the solution is one liter. Thus;

Molarity of hydrogen peroxide = 0.95/1 = 0.95 M.

Also recall that:

no of moles of a substance = mass of the substance/molar mass of the substance.

Thus;

mass of substance = no of moles x molar mass.

In this case, the no of moles of hydrogen peroxide is 0.95 while the molar mass is 34.01 g/mol. Hence;

mass of hydrogen peroxide = 0.95 x 34.01 = 32.31 g

Hence, a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution. The solution also has a hydrogen peroxide molarity of 0.95 M.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.

sveta [45]

Answer:

Starch is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

Cellulose is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

Glycogen is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

You work for the WWF. Write a letter to the mayor of a small farm town to explain why this town is experiencing erosion, and why

horrorfan [7]

The letter should contain concerns about the causes and ill effects of erosion.

<h3>Explanation:</h3>

Sir,

I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.

The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.

So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.

Thanking you,

XYZ.

xeze [42]

The word "cycle" in cell cycle refers to the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.
The cell cycle is the term that describes the development and growth of a cell, after its formation and until its reproduction (division into two daughter cells). In eukaryotic cells (cells that include a nucleus) the cell cycle is comprised of two major phases, the interphase and the mitosis. During interphase, the cell grows larger and duplicates its genetic material. During mitosis, the cell divides its genetic material and cytoplasm, creating two daughter cells.
