Calculate the reactance of a 2 H inductor that is connected to a battery with peak voltage 10 V and angular frequency 40 radians

/s.
Chemistry
1 answer:
NeX [460]3 years ago
4 0

Answer:

<em>The reactance is 80 Ω</em>

<em></em>

Explanation:

Inductance H = 2 H

voltage v = 10 V

angular speed ω = 40 rad/s

The reactance of an inductive ac circuit  X_{L} = ωL

X_{L} = 40 x 2 =<em> 80 Ω</em>

<em></em>

The current in the circuit is = V/X_{L} = 10/8 = 1.25 A

The solubility of acetanilide in hot water (5.5 g/100 ml at 100∘C) is not very great, and its solubility in cold water (0.53 g/
Olin [163]

Answer:

89.4%

Explanation:

Initially, there is 5.0 of the acetanilide in 100 mL of water, then the solution is chilled at 0ºC. The solubility represents the amount that the solvent (water) can dissolve of the solute (acetanilide). So, at 0ºC, 100 mL of water can dissolve till 0.53 g of the compound, the rest will precipitate and will be recovered.

So, the mass that is recovered is 5.0 - 0.53 = 4.47 g

The percent recovery is:

(4.47/5)x100% = 89.4%

When the volume of a gas is
Cerrena [4.2K]

Answer:

THE NEW VOLUME OF THE GAS IS 406 mL WHEN THE TEMPERATURE CHANGES FROM 765 K TO 315 K.

Explanation:

When the temperature changes from  765 K to 315K, the volume has changed from 986 mL to?

V1 = 986 mL = 0.986 L

T1 = 765 K

T2 = 315 K

V2 = unknown

Using Charles' equation of gas laws;

V1 / T1 = V2 / T2

Making V2 the subject of the formula:

V2 = V1 T2 / T1

V2 = 0.986 * 315 / 765

V2 = 0.406 L

V2 = 406 mL

So therefore, the volume of a gas changes from 986 mL to 406 mL as a result of a change in temperature from 765 K to 315 K.
