How does the highly reactive nature chlorine contribute to the creation of ozone holes in the upper atmosphere?
liberstina [14]
Chlorine is a halogen and is very reactive and unstable. If released in an elemental form (Cl2), it would react with other substances immediately. However, <span>chlorofluorocarbons (CFCs) which contain chlorine are unreactive and when released they eventually end up in the upper atmosphere still "intact". In the upper atmosphere, sunlight is more intense and is able to break apart CFC, releasing the highly reactive chlorine which in turns destroys ozone which is more abundant in the upper atmosphere (stratosphere). </span>

Convert 2.39 x 1022 molecules of water into moles of water
torisob [31]

Answer:

0.0397\ \text{mol}

Explanation:

Number of molecules of water = 2.39\times 10^{22}

N_A = Avogadro's number = 6.022\times 10^{23}\ \text{mol}^{-1}

Number of moles is given by

\dfrac{2.39\times 10^{22}}{6.022\times 10^{23}}

=0.0397\ \text{mol}

The number of moles of water is 0.0397\ \text{mol}.

How many liters of a 1.5 M solution can you make if you have .50 mol of KCl?
vaieri [72.5K]

Answer:

The answer to your question is 0.33 liters

Explanation:

Data

Volume = ?

Molarity = 1.5 M

number of moles = 0.5

Formula

Molarity = \frac{number of moles }{volume}

Solve for V

Volume = \frac{number of moles}{molarity}

Substitution

Volume = \frac{0.5}{1.5}

Simplification and result

       Volume = 0.33 l
