Answer: Sorry, I do not understand.
Indique dos diferencias entre la filtración por gravedad y la filtración al vacío.

So, let's go trough all the options:
A can't be the answer because a barometer is an instrument to measure atmospheric pressure, not density.
B seems like the answer but it's not. A density probe is used to measure density, temperature and level of fuel in the car, and not density of an object.
C is the answer, but it doesn't give you the answer directly. *
* We know that the formula of density is:
→ By putting the piece of ore inside the graduated cylinder with water, we can measure the ore's volume and by putting it on a balance, we can measure its mass and that is all we need to find it's density.

Answer:
As K >>> 1, the reaction will shift to the products
Explanation:
To know the direction of any reaction you must calculate the equilibrium constant, K. If K is < 1, the reaction will shift to the reactants and if k > 1 the reaction will shift to the products.
With the reactions:
<em>HSO₄⁻ ⇄ SO₄²⁻ + H⁺ Ka = 1.26x10⁻²</em>
And:
NH₄⁺ ⇄ NH₃⁺ + H⁺ Ka = 5.6x10⁻¹⁰
The inverse reaction:
<em>NH₃⁺ + H⁺ ⇄ NH₄⁺ 1/Ka = 1.8x10⁹</em>
<em />
The sum of the reactions:
HSO₄⁻ + NH₃⁺ + H⁺ ⇄ NH₄⁺ + SO₄²⁻ + H⁺ K = 1.26x10⁻² ₓ 1.8x10⁹ = 2.3x10⁷

Ethanoic acid ionizes in aqueous solutions to form two ions which are
and 
<h3>Ionization of ethanoic acid</h3>
Ethanoic acid goes by the chemical formula
.
In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:

A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single
