Answer:

77 moles

Explanation:

The given chemical compound is CCl2F2 is called Dichlorodifluoromethane. In CCl2F2, we have:

one mole of a Carbon atom.

two moles of Chlorine atom; &

two moles of Fluorine atom.

Given that one mole of Chlorine = 38.5 moles.

Then, two moles will be:

= 2 × 38.5 moles

= 77 moles

What is the energy of an electromagnetic wave with a frequency of 8 x 10^12

omeli [17]

Answer:

Energy, $E=5.3\times 10^{-21}\ J$

Explanation:

It is required to find the energy of an electromagnetic wave with a frequency of $8\times 10^{12}\ Hz$ . The energy of a wave in terms of its frequency is given by :

$E=h\nu$

$\nu$ = frequency of em wave

$E=6.63\times 10^{-34}\times 8\times 10^{12}\\\\E=5.3\times 10^{-21}\ J$

So, the energy of an electromagnetic wave is $5.3\times 10^{-21}\ J$

Equal amounts of N2 and O2 are added, under certain conditions, to a closed container. Which changes occur in the reverse reacti

geniusboy [140]

1) The forward reaction is N2 (g) + O2 (g) → 2NO

(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.

2) The equiblibrium equation is

N2 (g) + O2 (g) ⇄ 2NO

3) Then, the reverse reaction is

2NO → N2(g) + O2(g)

Answer: 2NO → N2(g) + O2(g)

Which one would be expected to happen? If one of the buffers that contribute to pH stability in human blood is carbonic acid (H2

vredina [299]

Answer:

The correct answer is option C.

Explanation:

$H_2CO3+H_2O\rightleftharpoons HCO_3^{-} + H_3O^+$

On increasing the pH of the blood the hydronium ions concentration will decrease which will result in decrease in concentration of hydronium ions at the equilibrium state of hydrogen carbonate.

Le-Chatelier's principle:

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

According to Le-Chatelier's principle , on decrease in a concentration of the product the equilibrium moves in forward correction to re-establish itself.

So, on increasing the pH, the hydronium ions concentration will decrease which results in disassociation of more hydrogen carbonate to maintain the pH of the blood.

Hence, the correct answer is option C.
