What is the volume of 120 x 1022 molecules of nitric oxide gas, NO, at si B) 2.24L C) 0.0199 L D) 5.02 A) 1120 L
Allisa [31]

Answer: 44.8 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

Standard condition of temperature (STP)  is 273 K and atmospheric pressure is 1 atm respectively.  

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}=\frac{120\times 10^{22}}{6.023\times 10^{23}}=2moles

1 mole of NO occupies volume = 22.4L at STP

Thus 2 moles of magnesium react with=\frac{22.4}{1}\times 2=44.8L

Thus the volume of 120\times 10^{22} molecules of nitric oxide gas is 44.8 L.

Can someone please quickly answer this question?
dimulka [17.4K]

Answer:

The difference between the two is:

[Kr]4d^1^05s^25p^2 is the Orbital Occupancy

[Kr]5s^24d^1^05p^2 is the Orbital Filling Order

Both are correct, I don't think your teacher will be so nit-picky to care.

Which of the following concerning solutions is/are correct? 1. The solvent in a mixture of gases is generally considered to be t
pshichka [43]

Answer: 1. The solvent in a mixture of gases is generally considered to be the substance in greater amount. 2. The solid dissolved in a solution is known as the solute. 3. Solid solutions are called alloys.

Explanation:

A binary solution is made up of two components ,called as solute and another as solvent.

A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase. A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.

Usually in liquid solutions , solid acts as solute and liquid acts as solvent. For example: In salt solution, salt is the solute and water is the solvent.

Solid solutions contains solid as solute and solid as solvent. These are called as alloys. For example : In brass, zinc is the solute and copper is the solvent.
