Two things that must be in circuits to make them work are a conductor and a voltage source.

<u>Explanation:</u>

There are tow main parts that helps all electric circuits to work. They are a conductor and a voltage source. Some of the other parts of circuits includes,switches and bulbs. The working of an electrical circuit is same as that of the human circulatory system. The blood is taken to all parts of human body with the help of the blood vessels in a circulatory system.

Same thing happens with an electrical circuit. This is responsible in taking current to all parts of an electrical system. In an electrical circuit electricity will flow from the voltage of high to low. A path should be there for conducting the electric power.

A mixture of He He , N 2 N2 , and Ar Ar has a pressure of 24.1 24.1 atm at 28.0 28.0 °C. If the partial pressure of He He is 301

Answer:

16.5 atm

Explanation:

<em>A mixture of He, N₂, and Ar has a pressure of 24.1 atm at 28.0 °C. If the partial pressure of He is 3013 torr and that of Ar is 2737 mm Hg, what is the partial pressure of N₂?</em>

The total pressure of a gaseous mixture is equal to the sum of the partial pressures.

P = pHe + pN₂ + pAr

pN₂ = P - pHe - pAr [1]

We need to express pHe and pAr in atm.

$pHe=3013torr.\frac{1atm}{760torr} =3.96atm$

$pAr=2737mmHg.\frac{1atm}{760mmHg} =3.60atm$

From [1],

pN₂ = 24.1 atm - 3.96 atm - 3.60 atm = 16.5 atm

P−aminobenzenesulfonic acid (sulfanilic acid) is normally written in the form shown but its zwitterionic form is more stable. wr

polet [3.4K]

Zwitterion is an ion consists of equal positive and negative charges on the same molecule which make it more stable and has high melting point
p-aminobenzene sulfonic acid contains both acidic (-SO₃H) and basic groups (NH₂), the acidic group will lose one proton to give (-SO₃⁻) and the basic group will gain this proton to give (-NH₃⁺)
The structure is:
