Answer:

29.47 g of AlCl₃.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2Al + 3Cl₂ —> 2AlCl₃

Next, we shall determine the mass of Al that reacted and the mass of AlCl₃ produced from the balanced equation. This can be obtained as follow:

Molar mass of Al = 27 g/mol

Mass of Al from the balanced equation = 2 × 27 = 54 g

Molar mass of AlCl₃ = 27 + (35.5× 3)

= 27 + 106.5

= 133.5 g/mol

Mass of AlCl₃ from the balanced equation = 2 × 133.5 = 267 g

SUMMARY:

From the balanced equation above,

54 g of Al reacted to produce 267 g of AlCl₃.

Finally, we shall determine the mass of AlCl₃ produced by the reaction of 5.96 g of Al. This can be obtained as follow:

From the balanced equation above,

54 g of Al reacted to produce 267 g of AlCl₃.

Therefore, 5.96 g of Al will react to produce = (5.96 × 267)/54 = 29.47 g of AlCl₃.

Thus, 29.47 g of AlCl₃ were obtained from the reaction.

Answer: The standard enthalpy of formation  of [tex]H_2O(g)[/tex] is  -252.1 kJ/mol.

Explanation:

The balanced chemical reaction is,

[tex]Fe_2O_3(s)+3H_2(g)\rightarrow 2Fe(s)+3H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=[n\times H_f_{products}]-[n\times H_f_{reactantss}][/tex]

Putting the values we get :

[tex]\Delta H=[2\times H_f{Fe}+3\times H_f{H_2O}]-[1\times H_f{Fe_2O_3}+3\times H_f{H_2}][/tex]

[tex]67.9kJ=[(2\times 0)+(3\times H_f{H_2O})]-[(1\times -824.2kJ/mol)+3\times 0kJ/mol)][/tex]

[tex]H_f{H_2O}=-252.1kJ/mol[/tex]

Thus standard enthalpy of formation  of [tex]H_2O(g)[/tex] is  -252.1 kJ/mol.

Answer:

[Ar] 4s2

Explanation:

The noble gas that comes before Ca is Ar, so that's what you'll use for the noble-gas shorthand part of it. Ca has two additional electrons in the 4s orbital, hence the 4s2.

The ground state electronic configuration of calcium using noble gas short hand notation is [Ar]4s².

Noble gas short hand notation comprises of the symbol of the last noble gas which is prior to the concerned atom which is followed by the configuration of the electrons which remains.

This notation helps in shortening of electronic configuration which is otherwise huge for elements with high atomic numbers.This is possible cause it uses the preceding noble gas configuration which accounts for that many electrons and the remaining electrons are filled in the next higher sub shell.

For calcium, preceding noble gas is argon which accounts for 18 electrons and for remaining two electrons they are placed in 4s sub shell thus making the total count of electrons to 20.

Answer:

Answer Below Hope Its Correct.

Explanation:

A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.

Instead of causing clouds and storms, some fronts just cause a change in temperature. However, some storm fronts start Earth's largest storms. Tropical waves are fronts that develop in the tropical Atlantic Ocean off the coast of Africa. These fronts can develop into tropical storms or hurricanes if conditions allow.

Fronts move across the Earth's surface over multiple days. The direction of movement is often guided by high winds, such as Jet Streams.  Landforms like mountains can also change the path of a front.

There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

Answer:

ΔH°r = -483.64 kJ

Explanation:

Let's consider the following balanced equation.

2 H₂(g) + O₂(g)  ⇒ 2 H₂O(g)

We can calculate the standard enthalpy change of the reaction (ΔH°r) using the following expression.

ΔH°r = ∑ΔH°f(p) × np - ∑ΔH°f(r) × nr

where

ΔH°f: standard heat of formation

n: moles

p: products

r: reactants

ΔH°r = ΔH°f(H₂O(g)) × 2 mol - ΔH°f(H₂(g)) × 2 mol - ΔH°f(O₂(g)) × 1 mol

ΔH°r = (-241.82 kJ/mol) × 2 mol - 0 kJ/mol × 2 mol - 0 kJ/mol × 1 mol

ΔH°r = -483.64 kJ

Answer: 0.056

Explanation:

The molarity of the solution is the ratio of the number moles of solute to the volume of solution. Hence, the molarity of the given solution is 0.056 M. Thus, option D is correct.

Molarity is a common term used to express the concentration of a solution . It is the ratio of the number of moles of solute to the volume of solution in liters.

Given that,

volume of HCl solution  = 9 L

Answer:

the percent error is -13.5%  

Explanation:

Given the data in the question;

Exact atomic weight = 65.38 g/mol

For approx

increased mass = 0.3681 g

moles = 6.514 x 10⁻³

we know that; moles = mass / (Atomic mass )

so

Atomic mass_[tex]_{approx[/tex] = mass / moles

Atomic mass_[tex]_{approx[/tex]  = 0.3681 / 6.514 x 10⁻³

Atomic mass_[tex]_{approx[/tex]  = 56.509

so approx atomic weight = 56.51 g/mol

we know that;

% error = ( [approx - exact] / exact ) × 100

we substitute

% error = ( [56.51 - 65.38]  / 65.38 ) × 100

% error = (-8.87 / 65.38 ) × 100

% error = ( -0.1356684 ) × 100  

% error = -13.5%  

Therefore, the percent error is -13.5%  

Answer: If [tex]\Delta G[/tex] for a reaction equals zero, the reaction is at equilibrium.

Explanation:

When a thermodynamic closed system tends to do the maximum amount of non-expansion work then the energy used to do this work is called Gibb's free energy.

The expression for [tex]\Delta G[/tex] can be written as follows.

[tex]\Delta G = \Delta H - T \Delta S[/tex]

where,

[tex]\Delta H[/tex] = enthalpy change

T = temperature

[tex]\Delta S[/tex] = entropy change

This means that [tex]\Delta G[/tex] is the difference between heat released in a process and the amount of heat released in a reversible manner for the same process. So, when the value of of [tex]\Delta G[/tex] comes out to be equal to zero then it means no heat is released or absorbed.

Hence, the reaction is stable or at equilibrium.

Thus, we can conclude that the value of [tex]\Delta G[/tex] = 0 then it means that the reaction is at equilibrium.

Answer:

0.668 atm

Explanation:

From the question given above, the following data were obtained:

Initial pressure (P₁) = 0.715 atm

Initial temperature (T₁) = 30 °C

Final temperature (T₂) = 10 °C

Volume = constant

Final pressure (P₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = 30 °C

Initial temperature (T₁) = 30 °C + 273

Initial temperature (T₁) = 303 K

Final temperature (T₂) = 10 °C

Final temperature (T₂) = 10 °C + 273

Final temperature (T₂) = 283 K

Finally, we shall determine the final. This can be obtained as follow:

Initial pressure (P₁) = 0.715 atm

Initial temperature (T₁) = 303 K

Final temperature (T₂) = 283 K

Final pressure (P₂) =?

P₁ / T₁ = P₂ / T₂

0.715 / 303 = P₂ / 283

Cross multiply

303 × P₂ = 0.715 × 283

303 × P₂ = 202.345

Divide both side by 303

P₂ = 202.345 / 303

P₂ = 0.668 atm

Thus, the final pressure of the hot air balloon is 0.668 atm
