Answer is *color of the solute*

If your answers are: A Nature of the solvent

B Temperature

C Nature of the solute

D Color of the solute

And the explanation is: D Solubility can be affected by the nature of the solute and solvent, temperature, and pressure. The color of the solute is not a factor because it does not affect solubility

Which of the following atoms is MOST likely to lose an electron?<br> Li<br> F<br> C<br> Rb
saveliy_v [14]

The atom that is most likely to lose an electron is lithium (Li).

<h3>What is electronegativity?</h3>

Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons when forming bonds.

On the other hand, electropositivity is the tendency of an atom to release electrons to form a chemical bond.

Chemical elements that lose electrons become positively charged while elements that gain electrons become negatively charged.

Metals are most likely to lose electrons to form positive ions. Examples of metals are lithium in group 1, calcium in group 2, aluminium in group 3 etc.

Assume that matter does not consist of atoms. Show by example how this assumption leads to
Leviafan [203]

If matter was not composed of atoms, the law definite proportions and law of multiple proportions will not hold true because compound would have random composition.

<h3>What is the law of definite proportions and law of multiple proportions?</h3>

The law of definite proportions states that all pure samples of a compound contains the same element in a fixed mass ratio.

The law of multiple proportions states that if an element combines with another element to form more than one compound, the mass of the element combines with a fixed mass of the other element in whole number multiples ratios.

Assuming matter was not composed of atoms, the law definite proportions and law of multiple proportions will not hold true because, their will be no definite ratio or composition in compounds.

The law definite proportions and law of multiple proportions are required for the atomic theory as they help prove that matter consists of definite unique particles called atoms.

In conclusion, the existence of atoms is proved true by the law definite proportions and law of multiple proportions.

Bromocresol green, Ka=2.0×10−5, is yellow in its protonated form (HX) and blue in its ionized form (X−). At what pH will bromocr
nydimaria [60]

Answer:

pH = 4,70

Explanation:

For bromocresol, as HX is yellow and X⁻ is blue, the indicator will be a perfect green color when HX = X⁻.

Using Henderson-Hasselbalch formula:

pH = pka + log [X⁻]/[HX] <em>(1)</em>

Where pka is -log ka = -log2,0x10⁻⁵ = 4,70

As HX = X⁻, [HX] / [X⁻] = 1

Replacing in (1):

pH = 4,70 + log 1

pH = 4,70 + 0

<em>pH = 4,70</em>

<em></em>

I hope it helps!
