Do you expect potassium iodide to be soluble in cyclohexane
Allushta [10]
Answer is: no, <span>potassium iodide has low solubility in cyclohexane.
</span>Potassium iodide (KI) is ionic compound, salt, that dissolve good in polar solvents (for example water), but it is very low soluble in non-polar solvents (in this example cyclohexane C₆H₁₂).
<span>Cyclohexane has zero net polarity, because it is a symmetric molecule, with sp2 hybridization of carbon.</span>

What volume of 1.25 M sodium hydroxide (NaOH) solution can be prepared using 60.0 g of sodium hydroxide? (The mass of one mole o
nataly862011 [7]

Answer:

The answer is

<h2>1.20 L</h2>

Explanation:

Since the concentration , mass and molar mass of NaOH has been given we use the formula

<h3>C =  \frac{m}{M \times v}</h3>

To find the volume

where

C is the concentration

m is the mass

M is the molar mass

v is the volume

Making volume the subject we have

<h3>v =  \frac{m}{C \times M}</h3>

From the question

C = 1.25 M

m = 60 g

M = 40.0 g/mol

Substitute the values into the above formula and solve for the volume

We have

<h3>v =  \frac{60}{1.25 \times 40}  \\ v =  \frac{60}{50}  \\ v =  \frac{6}{5}</h3>

We have the final answer as

<h3>Volume = 1.20 L</h3>

Hope this helps you

Illusion [34]

Answer:

1. A bond where electrons are transferred from one atom to another, resulting in charge imbalance in each atom is called ionic bonding.

2. A bond where electrons are equally shared, resulting in equal numbers of electrons orbiting each atom is called non-polar covalent bond.

3. A bond where electrons are unequally shared, resulting in more electrons orbiting certain atoms than others is called a polar covalent bond.

4. A bond where the electronegativity differences between the atoms within a molecule result in the partially positive atoms of one molecule attracting the partially negative atoms of other molecules is called polar bond and it is part of the covalent bonds.

Explanation:

1. In ionic bonding process, electrons are enterely transferred from one atom to another either losing or gaining negatively charged electrons, and the reacting atoms form ions. A charge imbalance is caused then by the oppositely charged ions, when attracted to each other by electrostatic forces, the basis of the ionic bond.

2. A non-polar covalent bond is occurs when two atoms have same electron afinity to share their electrons equally. The closer the values of their electron affinity, the stronger the attractionis. This is created in diatomic elements or gas molecules.

3. A polar covalent bond is a type of chemical bond where two electrons are unequally shared between two atoms, electrons are not equally shared because one atom spends more time with the electrons than the other atom, resulting in more electrons orbiting certain atoms than others.

4. The polar bond is a type of covalent bonds. This bonds depends on atoms´electronegativity differences. If an atom is less electronegative, it means that the electron distribution or charge is unevenly distributed or polarized and then it becomes partially positive.
