Explanation:

Sublimation is the conversion of a solid directly to a gas, without passing through the liquid state.

It occurs when the molecules of a solid have absorbed enough heat (kinetic energy) for some molecules to overcome the attractive forces of their neighbours and escape directly into the vapor phase.

One substance that sublimes at room temperature and pressure is CO₂ (dry ice).

Naphthalene is a substance that sublimes at room temperature and pressure.

Sublimation is defined as a process in which solid converts into gas directly without converting into liquid.

In the sublimation process, the reaction is an endothermic reaction, as the chemical bonds between molecules are broken down in order to release them into the air. Therefore ,the energy is released and so it is an endothermic reaction.

The heat or energy required to change the state from solid to gas is called the enthalpy of sublimation .Generally, it is expressed as KJ/m o l. Sublimation only occurs at pressures and temperatures .

Hence , Naphthalene is a substance that sublimes at room temperature and pressure.

Answer:

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

Explanation:

La ley de conservación de la materia establece que, dado que no se puede crear ni destruir ningún átomo en una reacción química, el número de átomos que están presentes en los reactivos debe ser igual al número de átomos presentes en los productos.

Luego, debes equilibrar la ecuación química. Para eso, primero debe mirar los subíndices al lado de cada átomo para encontrar el número de átomos en la ecuación. Si el mismo átomo aparece en más de una molécula, debes sumar sus cantidades.

Los coeficientes ubicados frente a cada molécula indican la cantidad de cada molécula para la reacción. Este coeficiente puede modificarse para equilibrar la ecuación, del mismo modo que nunca debe alterar los subíndices.

Al multiplicar el coeficiente mencionado por el subíndice, obtienes la cantidad de cada elemento presente en la reacción.

En este caso la reacción química es:

Fe₂O₃ + 3 H₂O ⇒ ____ Fe(OH)₃

Entonces, teniendo en cuenta todo lo anterior, se puede determinar la cantidad de elementos en cada lado de la ecuación:

Se puede observar que la reacción química no esta balanceada porque se tiene diferentes cantidades de cada elemento a cada lado de la reacción. Para equilibrarla, se comienza balanceando el hierro. Para eso, el coeficiente estequiométrico debe ser dos:

Fe₂O₃ + 3 H₂O ⇒ 2 Fe(OH)₃

Entonces:

Ahora, a cada lado de la reacción se tiene la misma cantidad de cada elemento, por lo que la reacción esta balanceada.

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

The [H₃O⁺] Hydronium ion concentration of the solution will be approximately 2.94 x 10⁻¹⁰ M.

To find the [H₃O⁺] concentration of a solution when the [OH⁻] concentration is known, we can use the Kw expression for water.

Kw = [H₃O⁺][OH⁻]

At 25 °C, the value of Kw is approximately 1.0 x 10⁻¹⁴.

Given that [OH⁻] = 3.4 x 10⁻⁵ M, we can substitute these values into the Kw expression;

(1.0 x 10⁻¹⁴) = [H₃O⁺](3.4 x 10⁻⁵)

Rearranging the equation to solve for [H₃O⁺], we get;

[H₃O⁺] = (1.0 x 10⁻¹⁴) / (3.4 x 10⁻⁵)

[H₃O⁺] ≈ 2.94 x 10⁻¹⁰ M

Therefore, the [H₃O⁺] concentration of the solution is 2.94 x 10⁻¹⁰ M.

Answer:

because the two are opposite compounds.

Explanation:

When Chlorine is passed through aqueous sodium fluorine then no reaction takes place between these two because of reactivity order of Fluorine and Chlorine

Displacement reaction is a reaction in which one atom replaces other atom from a molecule on the basis of reactivity strength.

The reason for such reactivity is that as we go down the group the number of shells increases so outermost shell is very far away from the nucleus. If any atom from outside coming to this nucleus then this nucleus is unable to attract the electron of that that atom. Reactivity of halogens is directly proportional to the electronegativity power of that element, that is power to attract electron. Reactivity of halogens decreases down the group.

So Chlorine is less reactive than Fluorine so Chlorine can not replace Fluorine from sodium fluoride. Hence no reaction will take place.

Elements

Explanation:

The   elements which are represented by a single uppercase letter, or represented by an uppercase letter followed  by a lowercase letter. This tells you the types of elements in the compound.

Elements are one of the simplest chemical substances that cannot be decomposed in a chemical reaction or by any chemical means. They are made up of small indivisible particles called atoms, all having the same number of protons.

Answer:

The equilibrium constant (Keq) for a reaction is a measure of the relative concentrations of the products and reactants at equilibrium. The equation for the equilibrium constant (Keq) is:

Keq = [H2O(g)][CO(g)] / [H2(g)][CO2(g)]

In order to find the Keq, we need to substitute the equilibrium concentrations of the species into the equation.

At equilibrium, there are 0.106 moles of H2, 0.106 moles of CO2, 0.094 moles of water and 0.094 moles of CO.

Keq = [0.094 moles H2O][0.094 moles CO] / [0.106 moles H2][0.106 moles CO2]

By canceling out the moles unit and substituting the number we got the value of Keq as:

Keq = 0.0940.094 / 0.1060.106

Keq = 0.87

Therefore, the Keq for this reaction is 0.87.

It is worth to note that the temperature, pressure and volume don't affect the Keq value but they affect the position of equilibrium.

To obtain the final chemical equation, we need to combine the given intermediate equations in a way that cancels out the common compounds and species.

The intermediate equations are:

P4O6(s) → P4(s) + 3O2(g)

P4(s) + 5O2(g) → P4O10(s)

To combine these equations, we can multiply equation 1 by 2 to balance the number of moles of P4:

2P4O6(s) → 2P4(s) + 6O2(g)

Now, we can add equation 2 to the modified equation 1 to cancel out the common compounds (P4 and O2) and obtain the final balanced chemical equation:

2P4O6(s) + P4(s) + 5O2(g) → 2P4(s) + 6O2(g) + P4O10(s)

Simplifying the equation, we have:

2P4O6(s) + P4(s) + 5O2(g) → 2P4O10(s)

Therefore, the final chemical equation from the given intermediate equations is:

2P4O6(s) + P4(s) + 5O2(g) → 2P4O10(s)

The final balanced chemical equation from the following intermediate chemical equations is 2P4O6(s) + P4(s) + 5O2(g) → 2P4O10(s).

Answer:

P= \(\frac{M}{V}\)

Explanation:

The equilibrium molar concentration of Cu²⁺(aq) is 7.59×10−4 M M. The assumption was made that the concentration of Cu²⁺(aq) is negligible compared to that of NH₃.

The simplifying assumption we make here is that the concentration of Cu²⁺(aq) coming from the Cu(NO₃)₂⋅6H₂O is negligible compared to that coming from the reaction with aqueous ammonia.

The balanced equation for the reaction of Cu²⁺ with aqueous ammonia is:

Cu²⁺(aq) + 4 NH₃(aq) ⇌ Cu(NH₃)₄²⁺(aq)

The overall formation constant, β4, is given by:

β4 = [Cu(NH₃)₄²⁺(aq)] / ([Cu²⁺(aq)] [NH₃(aq)]⁴)

At equilibrium, the concentrations of Cu(NH₃)₄²⁺(aq), Cu²⁺(aq), and NH₃(aq) are denoted by x, y, and z, respectively. Since one mole of Cu(NO₃)₂⋅6H₂O produces one mole of Cu²⁺(aq), the initial concentration of Cu2+(aq) is:

y0 = n / V = (12.5 g / 249.7 g/mol) / 0.500 L = 0.100 M

The equilibrium concentrations are related to the equilibrium constant by the mass balance equations:

x + y = y0

4x + z = 1.00 M

Substituting x = y0 - y into the second equation and solving for z gives:

z = 1.00 M - 4x = 1.00 M - 4(y0 - y) = 1.00 M - 4(0.100 M - y)

z = 1.00 M - 0.400 M + 4y = 0.600 M + 4y

Substituting the equilibrium concentrations into the expression for β4 gives:

2.1×10−13 = x / (y0 - y) z⁴

Simplifying and substituting in the expressions for x and z:

2.1×10−13 = (y0 - 2y) / (y0 - y) (0.600 M + 4y)⁴

Expanding the denominator and rearranging:

2.1×10−13 (y0 - y) = (y0 - 2y) (0.600 M + 4y)⁴

2.1×10−13 y0 - 2.1×10−13 y = (y0 - 2y) (0.600 M + 4y)⁴

Dividing by y0 - 2y and simplifying:

2.1×10−13 y0 / (y0 - 2y) - 2.1×10−13 = (0.600 M + 4y)⁴

At equilibrium, y is much smaller than y0, so we can neglect the term -2.1×10−13 and simplify further:

2.1×10−13 y0 / y0 = (0.600 M)⁴

Solving for y:

y = (2.1×10−13)^(1/4) (0.600 M) = 7.59×10−4 M

Therefore, the equilibrium molar concentration of Cu²⁺(aq) is approximately 7.59×10−4 M.

Therefore, there are approximately 0.1135 moles of sucrose in a can of cola.

Sucrose, also known as table sugar, has the chemical formula \(C_{12}H_{22}O_{11}\). The molar mass of sucrose can be calculated by adding up the atomic masses of each element in the molecule. Carbon, hydrogen, and oxygen are the main elements in sucrose and each have a unique atomic mass. By multiplying the number of atoms of each element by its atomic mass, we get the total molar mass of the molecule, which is 342.34 g/mol. To find the number of moles of sucrose in a sample, we divide the mass of the sample by its molar mass. In this case, 39 g of sucrose represents 0.1135 moles.

The set up shown in the image indicates that the bar magnet is free to roll on three small straws. The magnet has a north pole and a south pole, and its movement is affected by the surrounding magnetic field. To make the bar magnet move away from point X, we need to place an object that will create a magnetic field that interacts with the magnet's field.

As we know, opposite poles attract, and similar poles repel. Therefore, placing a magnet with a north pole at point X will cause the bar magnet to move away from it as the north pole of the bar magnet is attracted to the south pole of the new magnet. Similarly, placing a magnet with a south pole at point X will cause the bar magnet to move away from it as the south pole of the bar magnet is attracted to the north pole of the new magnet.
However, if we place a magnet with the same pole as the bar magnet at point X, the bar magnet will move towards it due to the repulsion between similar poles. Therefore, to make the bar magnet move away from point X, we need to place a magnet with the opposite pole as the bar magnet at point X.
In conclusion, placing a magnet with a north pole at point X will cause the bar magnet to move away from it. Similarly, placing a magnet with a south pole at point X will also make the bar magnet move away from it. It is essential to remember that opposite poles attract, and similar poles repel when working with magnetic fields.

It tells us how far the planet we are currently living on is towards our star (aka the sun) which is why that information/statement/claim is important.

It is due to low volume of electron that causes large distance between two electrons.

When the added electron goes to smaller quantum level, the repulsive force between two electrons is less because the electron which is added occupies small space due to less volume so there is a large distance between two electrons that leads to less force of repulsion.

If the electron has more volume so it occupies more space and there will more repulsive force between two electrons so that's why we can say that the smaller volume of electron is the reason of less repulsive force.
