Answer:

The volume will decrease.

Explanation:

According to Charles' Law, the volume of a gas is directly proportional to its temperature.

V = kT

Thus, if T decreases, V decreases.

Explanation:

So,when balloon filled with helium gas was placed in lower temperature we will observe that the volume of the helium gas inside the helium will decrease due to which size of the balloon will also get decreased.

This is because volume is directly proportional to the temperature of the gas at constant pressure and number of moles. And this law is known as Charles law of

$V\propto T$ (At constant pressure and number of moles)

What is the pressure in millimeters of mercury of 0.0130 molmol of helium gas with a volume of 210. mLmL at 55 ∘C∘C? (Hint: You

juin [17]

Answer : The pressure of the helium gas is, 1269.2 mmHg

Explanation :

To calculate the pressure of the gas we are using ideal gas equation:

$PV=nRT$

where,

P = Pressure of $He$ gas = ?

V = Volume of $He$ gas = 210. mL = 0.210 L (1 L = 1000 mL)

n = number of moles $He$ = 0.0130 mole

R = Gas constant = $0.0821L.atm/mol.K$

T = Temperature of $He$ gas = $55^oC=273+55=328K$

Putting values in above equation, we get:

$P\times 0.210L=0.0130mole\times (0.0821L.atm/mol.K)\times 328K$

$P=1.67atm=1269.2mmHg$

Conversion used : (1 atm = 760 mmHg)

Thus, the pressure of the helium gas is, 1269.2 mmHg

LenaWriter [7]

Answer:

The false statement is d Avery,Macleod and McCarty showed that DNA is the genetic information of cells and RNA is the genetic information in the viruses .

Explanation:

Avery,Macleod and MacCarty showed that DNA is the genetic material of the cell.

On the other hand Fraenkel, Conrat and Sanger carried out their experiment on tobacco mosaic virus to prove that RNA act as genetic material in some viruses.

A chemist has synthesized two new dyes based on the molecular structure of plant-based dyes. The lowest energy absorption line f

baherus [9]

Answer:

1. The dye that absorbs at 530 nm

Explanation:

With a larger HOMO-LUMO gap, there's also a higher absorption energy, so this means that the dye with the higher absortion energy has the larger HOMO-LUMO gap.

The relationship between energy and wavelenght can be expressed by the formula E = hc/λ, this means that the lower the wavelenght, the higher the energy is. So the dye that absorbs at a lower wavelenght has a larger HOMO-LUMO gap.
