Answer:

CH3OH > CH3Cl > CH4

Explanation:

The boiling point of a compound depends on the nature and magnitude of intermolecular forces acting between its molecules.

Methanol contains the -OH group, hence hydrogen bonds are dominant intermolecular forces in the compound. Presence of hydrogen bonds increases the boiling point of a substance, hence methanol has the highest boiling point followed by chloromethane which has dipole-dipole interaction as dominant intermolecular forces and methane having only weak dispersion forces as dominant intermolecular forces.

A marine biologist and her team capture 40 sea turtles and mark them before releasing them. The following year, they capture 60
NARA [144]

The estimated population of the sea turtles for that location is 160 turtles  

Let b represent the total turtles in the location.

<h3>Data obtained from the question</h3>
  • Marked turtle = 40
  • Captured turtle = 60
  • Captured marked turtle = 15
  • Total turtle = b =?

The estimated turtles in sea can be obtained as follow:

Mark in sea / Total in sea = captured marked turtle / Captured turtle

40 / b = 15 / 60

Cross multiply

b × 15 = 40 × 60

b × 15 = 2400

Divide both side by 15

b = 2400 / 15

b = 160 turtles

Thus, the estimated turtles in the sea is 160 turtles

In the oxidation of iron; how many grams of iron (III) oxide will be produced from 6.20 mol of Fe?
Flura [38]

Answer:

496 g of Fe₂O₃.

Explanation:

The balanced equation for the reaction is given below:

4Fe + 3O₂ —> 2Fe₂O₃

From the balanced equation above,

4 moles of Fe reacted to produce 2 moles of Fe₂O₃.

Therefore, 6.20 moles of Fe will react to produce = (6.20 × 2)/4 = 3.1 moles of Fe₂O₃

Finally, we shall determine the mass of 3.1 moles of Fe₂O₃. This can be obtained as follow:

Mole of Fe₂O₃ = 3.1 moles

Molar mass of Fe₂O₃ = (56 × 2) + (3×16)

= 112 + 48

= 160 g/mol

Mass of Fe₂O₃ =?

Mass = mole × molar mass

Mass of Fe₂O₃ = 3.1 × 160

Mass of Fe₂O₃ = 496 g

Therefore, 496 g of Fe₂O₃ were produced from the reaction.

What element contains the electron configuration 1s22s22p63s23p64s23d104p65s24d8 ?
RideAnS [48]
For better representation, the electronic configuration is written as:

<span>1s</span>²<span>2s</span>²<span>2p</span>⁶<span>3s</span>²<span>3p</span>⁶<span>4s</span>²<span>3d</span>¹⁰<span>4p</span>⁶<span>5s</span>²<span>4d</span>⁸

The letters s, p, d and f are subshells while the number coefficients represent the energy levels. Each subshell holds a specific maximum number of electrons, which is represented by the exponents. Thus, you add the exponents to determine the atomic number:

Atomic number = 2+2+6+2+6+2+10+6+2+8 = 46

From the periodic table, element 46 is Palladium or Pd.

Sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas. express your answer as a chemical equation. identify all
Firlakuza [10]
Sulfur trioxide (SO3) is a chemical compound that is a significant pollutant in gaseous form as it is involved in the production of acid rain. 

Industrially, sulfur trioxide is an important precursor to sulfuric acid and is formed from the reaction between sulfur dioxide (SO2) and oxygen gas (O2) as shown in the chemical equation below.
