<span>The number of molecules of each gas must be equal since 1 mol of any gas needs to contain 6.02x10^23 molecules. So 1mol O</span>₂ and 1mol CO both need to contain 6.02x10^23 molecules

Answer : Option C) The number of molecules.

Explanation : When comparing 1 mol of oxygen gas with 1 mol of carbon monoxide the number of molecules must be same. Each mole should contains 6.023 X 10^{23} atoms in it. Irrespective of the weight or atomic number avogadro's number remains constant for every mole of atom.

It is a number which is usually given for atoms or molecules, that are contained in the amount of substance given by one mole.

It is denoted by N_{A}.

The units of Avogadro's number can be expressed in terms of electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction.

Which water source becomes polluted as it travels over the earth?
never [62]

Run off

Explanation:

Run-off are the water sources that becomes polluted as they travel over the earth surface.

Surface run-off are water that moves on the earth surface. This water is a component of the water cycle which usually originate from precipitation.

  • As the water moves through different terrain it comes into contact with different pollutants.
  • Some of these run-off travels through mines, waste disposal sites among others.
  • This leads to the contamination of this form of water as it moves through these earth materials.
  • They are the most polluted water

A 1.0-L buffer solution is 0.10 M in HF and 0.050 M in NaF. Which action destroys the buffer? (a) adding 0.050 mol of HCl (b) ad
Volgvan

Answer:

(a) adding 0.050 mol of HCl

Explanation:

A buffer is defined as the mixture of a weak acid and its conjugate base -or vice versa-.

In the buffer:

1.0L × (0.10 mol / L) = 0.10 moles of HF -<em>Weak acid-</em>

1.0L × (0.050 mol / L) = 0.050 moles of NaF -<em>Conjugate base-</em>

-The weak acid reacts with bases as NaOH and the conjugate base reacts with acids as HCl-

Thus:

<em>(a) adding 0.050 mol of HCl:</em> The addition of 0.050moles of HCl produce the reaction of 0.050 moles of NaF producing HF. That means after the reaction, all NaF is consumed and you will have in solution just the weak acid <em>destroying the buffer</em>.

(b) adding 0.050 mol of NaOH: The NaOH reacts with HF producing more NaF. Would be consumed just 0.050 moles of HF -remaining 0.050 moles of HF-. Thus, the buffer <em>wouldn't be destroyed</em>.

(c) adding 0.050 mol of NaF: The addition of conjugate base <em>doesn't destroy the buffer</em>

Is gin a heterogeneous or homogeneous mixture?

Gin is uniform throughout and is a homogenous mixture. If it wasn't you would have awful lumps in your drink :). Hope I helped!
