Gas consisting of atoms exits through the eye of a needle 0.225 times faster than H2 gas. The chemical formula of the gas must be determined.

Rate1/Rate2 = square root M1/M2

\frac{Rate1}{Rate2}

<h2>Further explanation </h2>

The release of a gas molecule through a small hole is known as a gas effusion.

According to Graham's Effusion Law, the rate of gas effusion is inversely proportional to the square root of its molar mass.

The chemical formula of a substance states the type and a relative number of atoms contained in that substance. The number that states the number of atoms of an element in a chemical formula is called the index number. Chemical formulas can be either molecular formulas or empirical formulas.

Graham's Law is a formula formulated by Scottish chemist physicist Thomas Graham in 1848. Thomas Graham (1805-1869) studied the effusion rates of several gases. From his experiments, Graham found that the rate of gas effusion was inversely proportional to the root mass of the particle. In other words, at the same temperature and pressure, the speed of gas effusion is inversely proportional to root density. This statement is known as Graham's law.

This formula can be written:

Rate1/Rate2 = square root M1/M2

\frac{Rate1}{Rate2}

Where:

Rate1 is the first effusion rate of the gas (volume or number of moles per unit time).

Rate2 is the second gas effusion rate.

M1 is the molar mass of gas 1

M2 is the molar mass of gas 2.

Graham's law states that the speed of effusion or diffusion of a gas is inversely proportional to the root of a heavy molecule. Thus, if the molecular weight of one gas is greater than the other gas, the first gas will diffuse through a porous plug or escape through the needle's hole in the vessel at another gas transfer rate (heavier gas diffuses slower).

To determine what gas is this, we use Graham's Law of Effusion where it relates the rates of effusion of gases and their molar masses. We do as follows:

r1/r2 = √(M2 / M1)

Let 1 be the the unkown gas and 2 the H2 gas.

r1/r2 = 0.225
M2 = 2.02 g/mol

0.225 = √(2.02 / M1)
M1 = 39.90 g/mol

From the periodic table of elements, most likely, the gas is argon.

What is the relationship between the amount of substance ( concentration) and reaction rates?
jekas [21]

Answer:

Increasing the concentration of the reagents makes the collision between two molecules of the reagents more likely, thereby increasing the probability that the reaction will occur between these reagents.

As for the relationship between concentration and volume, density also comes into play, a higher volume, lower molarity and also lower concentration.

The pressure when increasing could generate a closer approach between the particles, therefore generating an increase in the reaction speed.

Pressure and volume are related but inversely proportional, therefore if the volume increases the pressure decreases and so on.

the reaction rate increases as the contact surface area increases. This is due to the fact that more solid particles are exposed and can be reached by reactant molecules.

A perfect reaction where the collision is promoted and the reaction speed advances is with the presence of a solvent, with an increase in pressure and a decrease in volume, with an increase in the exposure of the surface, with the presence of a catalyst, with increasing temperature and with increasing entrance

Explanation:

The reaction rate is defined as the amount of substance that is transformed into a certain reaction per unit of volume and time. For example, the oxidation of iron under atmospheric conditions is a slow reaction that can take many years but over time it is oxidized sooner or later by the oxygenation of its surface layer, but the combustion of butane in a fire is a reaction that happens in fractions of seconds, giving rise to an exothermic reaction with products such as CO2 and H2O

The white tern is a seabird that catches fish by plunging into the water. What physical features of the bird likely make this fe
V125BC [204]

White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.  

The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.
