Which of the following is ranked from smallest to largest?
Nuetrik [128]

Answer:

The order is: electron, carbon, water,  glucose, glycogen.    

Explanation:

The electron is a negatively charged subatomic particle and is therefore the smallest.

Carbon is a chemical element, which belongs to the group-14 of periodic table and has atomic number 6.

Water is a odorless, almost colorless and tasteless chemical compound which is necessary for all the known living form. The chemical formula is H2O and it is composed of 2 hydrogen atoms and one oxygen atom.

Glucose is a monosaccharide sugar and a type of simple carbohydrate. The chemical formula is C6H12O6 and is composed of 6 carbon atoms, 6 oxygen atoms and 12 hydrogen atoms.

Glycogen is a branched polysaccharide molecule, which is composed of multiple monomeric glucose units. Therefore, it is the largest.

<u>Therefore, the increasing order is: electron, carbon, water,  glucose, glycogen.</u>

If I have 0.725 moles of gas at a temperature of 105 K and a pressure of 3.75 atmospheres, what is the volume of the gas?
iVinArrow [24]

If I have 0.725 moles of gas at a temperature of 105 K and a pressure of 3.75 atmospheres the volume of the gas 1.66 litres.

Explanation:

Data given:

number of moles of the gas = 0.725

temperature = 105 K

pressure = 3.75 atm

volume of the gas =?

R = 0.08206 Latm/mole Kelvin

Applying the ideal gas law to calculate the volume of the given gas:

PV = nRT

rearranging the equation to calculate volume:

V = \frac{nRT}{P}

putting the values in the equation:

V = \frac{0.08206 X 0.725 X 105}{3.75}

V = 1.66 Litres.

At a temperature of 105 K and pressure of 3.75 atm, 0.725 moles of gas occupy 1.66 litres of volume.
