Addition reaction between water molecules and alkene molecules produces alcohol.

Addition reaction generally takes place across the unsaturated carbon compounds.

When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.

Hence formation of alcohol product takes place.

According to  the Charle's law as pressure is constant the new volume of gas is 4.907 L.

Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.

The graph of volume versus temperature is a straight line passing through the origin.The law was proposed by Jacques Charles , a french physicist in 1780.

In the given problem , on substituting values in above formula, V₂=3.8×278/359=4.907 L.

Thus , the new volume of methane gas is 4.907 L.

(1) The number of moles of oxygen gas is 0.123 mole.

(2) The volume occupied by the nitrogen gas is 50.75 Liters.

(3) The pressure exerted by the CO2 gas is 28.7 atm

(4) The temperature of the Cl2 gas is -118.37⁰C

The number of moles of oxygen occupied at the given condition is calculated as follows;

PV = nRT

n = PV/RT

where;

n = (2.5 x 1.2) / (0.08205 x 298)

n = 0.123 mol

PV = nRT

V = nRT/P

where;

V = (2 x 62.36 x 293) / (720)

V = 50.75 Liters

PV = nRT

P = nRT/V

where;

Molar mass of CO2 = 44

n = 25/44 = 0.568

P = (0.568 x 0.08205 x 308)/(0.5)

P = 28.7 atm

T = PV/nR

molar mass of Cl2 = 71 g

n = 5/71 = 0.07

T = (900 x 0.75)/(0.07 x 62.36)

T = 154.63 K

T = 154.63 - 273 = -118.37⁰C

Explanation:

Because we are given a 500. mL volumetric flask, the solution will have a volume of 500. mL.

Find the number of moles of zinc fluoride needed. Recall that molarity is simply moles per liter of solution:

[tex]\displaystyle 500.\text{ mL} \cdot \frac{0.173\text{ mol ZnF$_2$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.0865\text{ mol ZnF$_2$}[/tex]

Convert this to grams. The molecular weight of zinc fluoride is 103.38 g/mol:
[tex]\displaystyle 0.0865\text{ mol ZnF$_2$} \cdot \frac{103.38\text{ g ZnF$_2$}}{1\text{ mol ZnF$_2$}} = 8.94\text{ g ZnF$_2$}[/tex]

In conclusion, about 8.94 grams of solid zinc fluoride should be added.

The limiting reactant refers to the reactant that is in small amount. The extent of the reaction depends on the amount of the limiting reactant.

The term limiting reactant refers to the reactant that is in small amount, We shall now solve the questions individually.

1) The reaction equation is;

CaO + H2O → Ca(OH)2

Number of moles of CaO = 10 g/56 g/mol = 0.18 moles

Number of moles of H2O = 10 g/18 g/mol = 0.56

Since the reaction is 1:1, CaO is the limiting reactant

Mass of calcium hydroxide = 0.18 moles * 74 g/mol = 13.32 g

2) The reaction equation is;

Mg + Br2 → MgBr2

Number of moles of Mg = 1 g/24 g/mol = 0.042 moles

Number of moles of Br2= 5 g/160 g/mol = 0.031 moles

Since the reaction is 1:1, Br2 is the limiting reactant

Mass of MgBr2 =  0.031 moles * 184 g/mol = 5.7 g

3) The reaction equation is;

CuO + H2 → Cu + H2O

Number of moles of CuO= 2.00 g/80 g/mol = 0.025 moles

Number of moles of H2 = 1.00g/2 g/mol = 0.5 moles

Since the reaction is 1:1, CuO is the limiting reactant

Mass of Cu = 0.025 moles * 63.5 g/mol = 1.59 g

4) The reaction equation is;

2Na + F2 → 2NaF

Number of moles of Na = 2.30 g/23 g/mol = 0.10 moles

Number of moles of F2 =  2.85 g/38 g/mol = 0.075 moles

If 2 moles of Na react with 1 mole of F2

x moles of  Na reacts with 0.075 moles of F2

x = 0.15

Hence Na is the limiting reactant

Mass of NaF = 0.10 moles * 42 g/mol = 4.2 g

5) The equation of the reaction is;

Fe2O3 + 2Al → 2Fe + Al2O3

Number of moles of Fe2O3  =  8.00 g/160 g/mol = 0.05 moles

Number of moles of Al = 2.16 g/27 g/mol = 0.08 moles

If 1 mole of Fe2O3  reacts with 2 mole of Al

x moles of Fe2O3 reacts with 0.08 moles of Al

x = 0.04 moles

Hence, Fe2O3 is the limiting reactant

1 mole of Fe2O3  yileds 2 moles of Fe

0.05 moles yileds 0.05 moles  * 2 moles/1 mole = 0.1 moles

Mass of Fe = 0.1 moles * 56 g/mol = 5.6 g

6) The equation of the reaction is;

2Al + 3Cl2 → 2AlCl3

Number of moles of Al = 13.5 g/27 g/mol = 0.5 moles

Num ber of moles of Cl2 =  42.6 g /71 g/mol = 0.6 moles

If 2 moles of Al reacts with 3 moles of Cl2

x moles of Al reacts with 0.6 moles of Cl2

x = 0.4 moles

Al is the limiting reactant

Mass of AlCl3 = 0.4 moles * 133 g/mol = 53.2 g

Intermolecular forces: These are the attractive or repulsive forces acting between two molecule in interaction.

The attractive forces between molecules are of several types based on the interaction between molecules also known as Vander wall forces.

Bonding forces: They are also attractive forces acting between two constituents (atom, ion, radicals etc) and stabilizes the constituent particles by loss of energy. The bond between any two species are formed by the overlapping of corresponding orbitals.

Whenever positive overlapping occurs between species, the formation of Bonding molecular orbital (BMO) takes place. and when electron enters into BMO it loses energy. Alternative form of explaining the concept is Individual electron possess more energy than the electrons that paired or Bonded.

Now coming to your question,

All the intermolecular forces are formed by weak attractive forces (vanderwall forces) which includes Ion-dipole forces, Ion-induced-dipole forces, Dipole-dipole forces, Dipole-induced-dipole forces, Hydrogen bonds & London forces.

All these forces are temporary and weak, and formed by the poles generated on molecule due to shift of electron, for e.g. Any molecule having more electron at one pole and less electron at another pole then that molecule start acting as charged body when that charged body comes in contact with opposite pole of another charged body the interaction takes place, since the electrons are dynamic and unsteady it's not possible that the pole will keep acting same as before. hence the intermolecular forces are generally weaker.

On the other side the Bonding electrons, are formed by the various strong overlapping such as between Head to Head overlapping leads to formation of Sigma bond which is the strongest bond takes alot of Energy to break & Lateral overlapping lead to formation of pi bond which is also stronger bond than that of Hydrogen bond.
