The volume at STP of the following compounds: 0,01 mol of hydrogen chloride gas is 0.224 L.

As we know, one mole of a gaseous substance occupies 22.4 litre, so volume occupied by 0.01 mole hydrogen chloride gas is 0.224 L.

The equation characterising the states of hypothetical gases stated mathematically by combinations of empirical and physical constants is known as the Ideal Gas Equation. It is the relationship between pressure, volume, moles, and temperature.

The ideal gas equation was developed by merging many gas laws, including Charles' law, Boyle's law, Gay-law, Lussac's and Avogadro's law. The equation of state of a hypothetical ideal gas is the ideal gas law. It approximates the behaviour of gases under certain conditions.

An ideal gas is a fictitious gas composed of randomly moving particles that collide in totally elastic collisions. Even while there is no such thing as an ideal gas, most gases tend to exhibit these characteristics as their density lowers. This occurs because the intermolecular distances between gas molecules are so great that they do not interact.

Hence, in all the standard conditions of temperature, pressure and number of moles, the molar volume is 22.4 Litre which is also considered as a standard.

A contestants spin a wheel when it is their turn in a game show. One contestant gives the wheel an initial angular speed of 3.40
guajiro [1.7K]

Answer:

4.62 s

Explanation:

We are given that

Initial angular speed,\omega=3.4 rad/s

\theta=1\frac{1}{4} rev=\frac{5}{4}\times 2\pi=2.5\pi rad

\omega'=0

\omega'^2-\omega^2=2\alpha \theta

Substitute the values

0-(3.4)^2=2\times 2.5\pi \alpha

\alpha=\frac{-(3.4)^2}{2\times 2.5\pi}=-0.736 rad/s^2

\omega'=\omega+\alpha t

0=3.4-0.736 t

-0.736t=-3.4

t=\frac{-3.4}{-0.736}=4.62 s

Hence, the wheel takes 4.62 s to come to rest.
