A solution is a homogenous mixture of solute and solvent. there are different types of solutions. a carbonated drink is an examp

le of a solution where the solute is a gas and the solvent is a liquid. sugar crystals dissolved in water is an example of a solution where the solute is a solid and the solvent is liquid. acetic acid is miscible in water, forming a solution commonly known as vinegar. in this case, both the solute and the solvent are liquids. the solubility of solute in a solvent depends on various parameters, such as temperature, pressure, the nature of the solute, and the nature of the solvent. considering these parameters, identify the statements that are correct for the solubility of a solute in a solvent. check all that apply. hints check all that apply. table salt dissolves in water to form a solution. gases are readily soluble in water at higher temperatures. ethanol and hexane are miscible. zinc sulfate is soluble in water. carbon dioxide gas will be more soluble in water when the partial pressure is high.

The following statements are correct:
ZINC SULPHATE ARE SOLUBLE IN WATER.
TABLE SALT DISSOLVES IN WATER TO FORM A SOLUTION.
CARBON DIOXIDE GAS WILL BE MORE SOLUBLE IN WATER WHEN THE PARTIAL PRESSURE IS HIGH.

Answer:

The correct statements are:  

1. Table salt is soluble in water, table salt (NaCl) get dissociate in water as NaCl = Na+ + Cl-.  

2. Zinc sulfate is also soluble in water, as zinc sulfate gets dissociate in water as ZnSO4 = Zn2+ + SO42-.  

3. The solubility of carbon dioxide gas in water increases with partial pressure and drops down with the drop in partial pressure.  

The incorrect statements are:  

1. Gases do not get easily soluble in water at high temperatures. The higher kinetic energy makes more motion in the molecules of gas which dissociate intermolecular bonds and escape from solution.  

2. Ethanol and hexane are not miscible, as ethanol is hydrophilic due to the presence of -Oh group and hexane is hydrophobic. So, these compounds will not mix.

Determine the vapor pressure (atm) of rubbing alcohol (isopropanol) at 20.0 °C. The normal boiling point of isopropanol is 82.3
jeyben [28]
Here we apply the Clausius-Clapeyron equation:
ln(P₁/P₂) = ΔH/R x (1/T₂ - 1/T₁)

The normal vapor pressure is 4.24 kPa (P₁)
The boiling point at this pressure is 293 K (P₂)
The heat of vaporization is 39.9 kJ/mol (ΔH)
We need to find the vapor pressure (P₂) at the given temperature 355.3 K (T₂)

ln(4.24/P₂) = 39.9/0.008314 x (1/355.3 - 1/293)
P₂ = 101.2 kPa

Draw the condensed structural formulas for all the possible haloalkane isomers that have four carbon atoms and a bromine.
meriva

<u>Answer:</u> The isomers are shown in the image below.

<u>Explanation:</u>

Isomers are defined as the chemical compounds having the same number and kinds of atoms but arrangement are different.

For the alkane having four carbon atoms and 1 bromine atom, the IUPAC name of the haloalkane is bromobutane

There are 4 possible isomers for the given haloalkane compound:

  1. 1-bromobutane
  2. 2-bromobutane
  3. 1-bromo-2-methylpropane
  4. 2-bromo-2-methylpropane

The isomers of the given organic compound is shown in the image below.

The p subshell can hold up to eight electrons in an atom (2 points)<br> True or false?
hoa [83]

Answer: The statement is false

Explanation:

Electrons occupy a region in atoms known as orbitals or subs hell.  These orbitals include

I) S-orbital: it can occupy a maximum of two electrons

II) P-orbital: It occupies a maximum of six electrons

III) D-orbital: it occupies a maximum of ten electrons

F and G-orbitals as examples of other orbitals present.

A good illustration of the 6 electrons occupied by the P-subshell is seen in Sodium (Na) with atomic number of 11

Na = 1s2, 2S2 2p6, 3s1

Note: extra electrons are transferred to the next orbital
