Answer:

There are two correct choices:

<em>Real gas particles have significant volume</em>
<em>Real gas particles have more complex interactions than ideal gas particles.</em>

Explanation:

<em>Ideal gases </em>are not real; ideal gases are a theoretical model used to confere a better understanding of gas properties. This model permits to predict the behavior of the gases using the ideal gas law, which is valid under certain conditions (mainly low pressure and high temperature).

Kinetic molecular theory states these basic assumptions for gases:

Gas particles are in constant, random motion.

Gas particles move in a straight line until they collide with another particle or the walls of the container.

Gas particles are much smaller than the distance between particles, so most of the volume of a gas is therefore empty space, and the particles are considered to occupy no space.

There is no force of attraction acting on gas particles nor between them

Collisions are perfectly elastic, meaning that no energy is lost durign collisions.

Those conditions are not perfected matched by real gas particles, since real gas particles do occupy a volume and interact with each other, this is r<em>eal gas particles have significant volume and have more complex interactions than ideal gas particles.</em>

<h2>Answer </h2>

Option 1 - Real gases are always hotter than the ideal gases.

<u>Explanation </u>

Gases that are different from ideality are called real gases because they are always hotter than the ideal gases as they are flying past each other at an extremely high speed that creates kinetic energy. Whereas idea gases have absolutely elastic collisions, this is as it has a valuable theory because it embraces the perfect concept of original gas law.

<h2>Answer </h2>

Option 2 - Real gases particles have significant volume.

<u>Explanation </u>

Real gases have significant volume because they have a high temperature and have a higher volume as compared to ideal gases. There is a general gas theory that is composed of several randomly crossing point particles. Several gases, for example, nitrogen, oxygen, and hydrogen can be manipulated like ideal gases within a generous immunity of the idea gas.

<h2>Answer </h2>

Option 3 - Real gases particles are smaller than an ideal gas.

<u>Explanation </u>

Real gas particles are smaller than ideal gas particles since they have a volume and are made up of molecules or atoms that typically take up some space than the ideal atoms. The ideal gas pattern manages to break at moderate temperatures level or greater pressures point when intermolecular energies and molecular mass enhances to be significant.

The radioactive atom 61/27 co emits a beta particle. write an equation showing the decay

pickupchik [31]

Answer:

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}$

Explanation:

The unbalanced nuclear equation is

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, ?$

Let's write the question mark as a nuclear symbol.

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{Z}^{A}\text{X}$

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.

Then

60 = 0 + A, so A = 60 - 0 = 60, and

27 = -1 + Z, so Z = 27 + 1 = 28

Your nuclear equation becomes

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{X}$

Element 28 is nickel, so the balanced nuclear equation is

$\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}$

85g=kg?<br> Unit conversion.

Paraphin [41]

Answer:

0.085 kg

Explanation:

1 g=0.001 kg OR 1 kg=1000 g

so $\frac{85}{1000}$ =0.085 kg

How many moles of n are in 0.163 g of n2o?

zimovet [89]

First convert 0.163 grams of N2O to mol by dividing it with the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.

noname [10]

Answer:

C₂H₆O + 3 O₂ = 2 CO₂ + 3 H₂O

Explanation:

Combustion is an example of an oxidation reaction. Many fuels contain carbon and hydrogen atoms. These fuels burn to produce oxides, carbon dioxide and water.
