This is called as such because the proton or H+ has taken on both lone electron pairs on the oxygen in the water molecule. As such it is s coordinate covalent bond.

Answer:

The bond formed between $H^{+}$ ion and water molecule is a type of coordinate covalent bond where both the bonding electrons are shared from the oxygen atom of the $H_{2}O$ molecule.

Explanation:

Actually, the coordinate covalent bonds are such bonds which are formed when only one atom shares both the bonding electrons with another atom to form a bond.

Here, the hydrogen ion has only one proton and so it can not share electrons for bond formation. Hence, it accepts one lone pair of electrons from the oxygen atom of the water molecule and thus forms a coordinate covalent bond.

The coordinate covalent bonding between $H^{+}$ ion and water molecule is shown as:

The correct order given below shows the changes that occurs in a mice population in response to changes in their environment:

The population of mice is in an environment with many black rocks
Mice with black for are more likely to survive and reproduce than mice with brown fur
After many generations, most of the mice in the population have black fur
A sandstorm covers most of the population's environment with brown sand
Mice with black fur are less likely to survive and reproduce than mice with brown fur
After many generations, most of the mice in the population have brown fur

<h3>What is the correct order for natural selection in the desert environment given?</h3>

Based on the process of natural selection due to envrionmental pressures, the population of the mice in the desert changes as follows before and after the environmental change:

The population of mice is in an environment with many black rocks
Mice with black for are more likely to survive and reproduce than mice with brown fur
After many generations, most of the mice in the population have black fur
A sandstorm covers most of the population's environment with brown sand
Mice with black fur are less likely to survive and reproduce than mice with brown fur
After many generations, most of the mice in the population have brown fur

Therefore, the correct order shows the changes that occurs in a mice population in response to changes in their environment.

An equimolar mixture of acetone and ethanol is fed to an evacuated vessel and allowedto come to equilibrium at 65°C and 1.00 atm

frutty [35]

The question is incomplete, the table of the question is given below

Answer:

I) xA= 0.34, yA= 0.55

ii) 76.2 mole % vapor

iii) Percentage of vapor volume = 98%

Explanation:

i) xA= 0.34, yA= 0.55

xA= 0.34, yA= 0.55

ii) 0.50 = 0.55 nv + 0.34 nL

Therefore, nV = 0.762 mol vapor and nL = 0.238 mol liquid

This shows 76.2 mole % vapor

iii) ρA= 0.791 g/cm3 and, ρE = 0.789 g/cm3

Therefore, ρ = 0.790 g/cm3

Now, we have:

MA = 58.08 g/mol and ME= 46.07 g/mol

So Ml = (0.34 x 58.08)+[(1 -0.34) x 46.07] = 50.15 g/mol

1 mol liquid = (0.762 mol vapor/0.238 mol liquid) = 3.2 mol vapor

Liquid volume = Vl= [1 mol x (50.15 g/mol)] / (0.790 g/cm3) = 63.48 cm3

Vapour volume = Vv = 3.2 mol x(22400 cm3/mol) x [(65+273)/273] = 88747 cm3

Therefore, percentage of vapour volume = 88747 / (88747+63.48) = 99.9 %

You unknowingly run over a small nail while driving and it punctures your tire. When you are getting in your car the next mornin

Norma-Jean [14]

The nails can puncture the tires of the vehicles making them deflated after a while. The process of tire deflation due to a puncture is due to the process called an effusion. Thus, option c is correct.

<h3>What is effusion?</h3>

Effusion is the process that defines the escape of the fluids or gases from a system through an outlet with a small diameter compared to the mean free path of the molecules.

When a tire is punctured then the gas from the tire starts to move out through the hole through effusion. This leads to deflation of the tire after some time as all the gas present inside had moved out completely.

Therefore, option c. a punctured tire deflates due to effusion.
