6 0

Answer:

The same number of molecules, 6.0 × 10²³ molecules.

Explanation:

The amount of any given gas that can be stored in a container depends on the <u>temperature, pressure and volume </u>of the container. It does not depend on the nature (or identity) of the gas.

So if a 10-liter flask contains 6.0 × 10²³ molecules of hydrogen gas, it will contain the same amount of molecules of any other gas when temperature and pressure remain constant.

which ionic bond is stronger: the ionic bond between calcium ions and chloride ions in crystalline calcium chloride , or the ion
monitta

CaCl2 has a stronger ionic bond than KCl because Ca+2 is smaller than K+ in size.

<h3>What is the working of ionic bonds ?</h3>

A stable link formed by the complete transfer of the valence electron is known as an ionic bond. This kind of interaction results in the formation of positive ions, also known as cations, and negative ions, also known as anions.

  • This kind of interaction is exemplified by the ionic bond in sodium chloride, a salt. The sodium valence electron is transferred to the outer electron shell of chloride. Ionic molecules form the basis of ionic compounds.

  • The three types of bonds that frequently develop are covalent bonds between nonmetals, ionic bonds between metals and nonmetals, and metallic connections between metals.

If a substance has a mass of 12.50 g and takes up 3.4 mL of space, what is the density?
miskamm [114]

Answer:

The answer is

<h2>3.68 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

density =  \frac{12.50}{3.4}  \\  = 3.676470588...

We have the final answer as

<h3>3.68 g/mL</h3>

Hope this helps you

Why can scientists ignore the forces of attraction between particles in a gas under ordinary conditions
Alika [10]
<span>Scientists ignore the forces of attraction between particles in a gas under ordinary conditions</span><span> because the particles in a gas are apart and moving fast, rather than clustered and moving slow, therefore the forces of attraction are too weak to have a visible effect.</span>
