Why would an atom have zero charge

Chemistry
1 answer:
iragen [17]3 years ago
4 0

Answer:

The overall charge of an atom is zero. ... The charge from a proton or electron are of equal strength, therefore if an atom has an equal number of protons and electrons, it will be electrically neutral. However, atoms are not always electrically neutral, in which case they are called ions.

Explanation:

Sorry if it's wrong!!!!

How many moles of SO2 are required to produce 0.45 mole CS2?
Kaylis [27]

Answer: The moles of carbon needed will be, 13.8 moles

Explanation: Moles of  = 5.52 mole

Now we have to calculate to moles of carbon.

The given balanced chemical reaction is,

From the balanced chemical reaction, we conclude that

As, 2 mole of  react to give 5 moles of carbon

So, 5.52 mole of  react to give  moles of carbon

Therefore, the moles of carbon needed will be, 13.8 moles

A gas mixture contains ar and h2. what is the total pressure of the mixture, if the mole fraction of h2 is 0. 350 atm and the pr
nasty-shy [4]

Considering the Dalton's partial pressure, the total pressure in the mixture of gases is 1.371 atm.

The pressure exerted by a particular gas in a mixture is known as its partial pressure.

So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

P_{T} = P_{1}+P_{2}+......+P_{n}

where n is the amount of gases in the mixture.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture.  So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

P_{A} = X_{a}P_{T}

In this case, the partial pressure of gas H₂ can be expressed as:

P_{H2} = X_{H2} P_{T}

You know:

P_{H2} = 0.48 atm

X_{H2} = 0.35

Replacing in the definition of partial pressure of gas H₂:

0.48atm = 0.35P_{T}

Solving:

P_{T} = \frac{0.48atm}{0.35}

P_{T}= 1.371 atm

In summary, the total pressure in the mixture of gases is 1.371 atm.
