Explanation:

Plasma is a state of matter which is a hot ionized gas and it contains molecules with positive ions and negative electrons.

Since there is high kinetic energy of molecules so, there is swirling gas of positive ions and negative electrons. As a result, there will be release of electrons.

For example, lightening is an example of partially ionized plasma.

G. whose vapour
german

Answer:

8.33 hours

Explanation:

In order to solve this problem, we must apply Graham's law of diffusion in gases. Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its vapour density. For two gases we can write;

R1/R2=√d2/d1

Where;

R1= rate of diffusion of hydrogen

R2= rate diffusion of unknown gas

d1= vapour density of hydrogen

d2= vapour density of the unknown gas

Volume of hydrogen gas = 360cm^3

Time taken for hydrogen gas to diffuse= 1 hour =3600 secs

R1 = 360 cm^3/3600 secs = 0.1 cm^3 s-1

Vapour density of unknown gas = 25

Vapour density of hydrogen = 1

Substituting values,

0.1/R2 = √25/1

0.1/R2 = 5/1

5R2 = 0.1 × 1

R2 = 0.1/5

R2= 0.02 cm^3s-1

Volume of unknown gas = 600cm^3

Time taken for unknown gas to diffuse= volume of unknown gas/ rate of diffusion of unknown gas

Time taken for unknown gas to diffuse= 600/0.02

Time= 30,000 seconds or 8.33 hours

Digiron [165]

3 moles of NaOH reacts with 1 mole of phosphoric acid.

<h3>What is the moles ratio of the NaOH and Phosphoric acid reaction?</h3>

The moles ratio of the reaction between NaOH and Phosphoric acid is given by the equation of the reaction below:

3\:NaOH + H_{3}PO_{4} \rightarrow Na_{3}PO_{4} + 3\:H_{2}O \\

Based on the equation of the reaction, 3 moles of NaOH reacts with 1 mole of phosphoric acid.

The Millikan oil-drop experiment, which was the first experiment to measure the charge of the electron, compared the electrical
Liono4ka [1.6K]

Answer:

True

Explanation:

The oil drop experiment was carried out by Robert Millikan and Harvey Fletcher in 1909 to determine the charge of an electron. By balancing downward gravitation force with upward drag and electric force, they suspended small charged droplets of oil between two metal electrodes.

The charge over an oil droplet was often an integral value of e, was determined by changing the intensity of the electric field.

So, the given statement is true
