The ionization energy of B^{4+} is 3.28199 \cdot 10^{7} \mathrm{~J} / \mathrm{mol}$$.

<h3>What is ionization energy?</h3>

It is the energy needed to remove one electron from a neutral atom, which results in the formation of an ion.

The measurement is based on an isolated atom in its gaseous phase and is often expressed in kJ/mol.

b) Atom is ionized when the electron is completely removed from its electron cloud (so it being moved from first, $n_{\text {initial }}=1$ to the infinity's shell and $n_{\text {final }}=\infty$ ), and now the equation can be written as

$$\Delta E=-2.18 \cdot 10^{-18} J\left(\frac{1}{n_{\text {final }}^{2}}-\frac{1}{n_{\text {initial }}^{2}}\right)\\=-2.18 \cdot 10^{-18} J\left(\frac{1}{\infty^{2}}-\frac{1}{1}\right)$$

So the ionization energy is affected by the charge of the nucleus and the general formula can be represented as:

$\Delta E_{I E}=-2.18 \cdot 10^{-18} J\left(\frac{1}{\infty^{2}}-\frac{1}{1}\right) \cdot Z^{2} \cdot\left(6.022 \cdot 10^{23}\right molecules/mol)$ and as $\frac{1}{\infty}=0$

$$\begin{gathered}\Delta E_{I E}=-2.18 \cdot 10^{-18} \mathrm{~J} \cdot Z^{2} \cdot\left(6.022 \cdot 10^{23} \text { molecules } / \mathrm{mol}\right) \\\Delta E_{I E}=1.312796 \cdot 10^{6} \mathrm{~J} / \mathrm{mol} \cdot Z^{2}\end{gathered}$$

The $B^{4+}$ has an atomic number Z=5, therefore using the formula when $n_{\text {initial }}=1, we get

$$\Delta E_{I E}=1.312796 \cdot \mathrm{J} / \mathrm{mol} \cdot 5^{2}\\=3.28199 \cdot 10^{7} \mathrm{~J} / \mathrm{mol}$$

The ionization energy of B^{4+} is 3.28199 \cdot 10^{7} \mathrm{~J} / \mathrm{mol}$$.

A catalyst lowers the activation energy for both the forward and the reverse reactions in an equilibrium system, so it has no ef
rosijanka [135]

Answer:

True.

Explanation:

  • Catalyst increases the rate of the reaction without affecting the equilibrium position.
  • Catalyst increases the rate via lowering the activation energy of the reaction.
  • This can occur via passing the reaction in alternative pathway (changing the mechanism).
  • The activation energy is the difference in potential energies between the reactants and transition state (for the forward reaction) and it is the difference in potential energies between the products and transition state (for the reverse reaction).
  • in the presence of a catalyst, the activation energy is lowered by lowering the energy of the transition state, which is the rate-determining step, catalysts reduce the required energy of activation to allow a reaction to proceed and, in the case of a reversible reaction, reach equilibrium more rapidly.
  • with adding a catalyst, both the forward and reverse reaction rates will speed up equally, which allowing the system to reach equilibrium faster.

How would you classify the following events?
ICE Princess25 [194]

Answer:  Event 1 is an example of a physical change and Event 2 is an example of a chemical change.

Explanation: Physical change is one in which there is no change in chemical composition of the substance. There is only a change in phase change.

Chemical change is a change in which there is a change in chemical composition and there might or might not be a phase change.

On Boiling, the water molecules remain bonded in the same form and only covert from liquid to gaseous form, thus is a physical change.

On Rusting of iron nail, the iron changes to iron oxide by combining with oxygen, there is a rearrangement of atoms and thus is a chemical change.

Fe+O_2+H_2O\rightarrow Fe_2O_3.xH_2O

If 1.320 moles of CH4 reacts completely with oxygen, how many grams of H2O can be formed
Rainbow [258]

Answer:

47.5 g of water can be formed

Explanation:

This is the reaction:

CH₄  +  2O₂  →  CO₂ + 2H₂O

Methane combustion.

In this process 1 mol of methane react with 2 moles of oxygen to produce 2 moles of water and 1 mol of carbon dioxide.

As ratio is 1:2, I will produce the double of moles of water, with the moles of methane I have.

1.320 mol  .2 = 2.64 moles

Now, we can convert the moles to mass (mol . molar mass)

2.64 mol . 18g/mol = 47.5 g

A 12 gram piece of metal is heated to 300 °C from 100 °C with 1120 Joules of energy. What is the specific heat of the metal?
Sergeeva-Olga [200]

Answer:

The specific heat for the metal is 0.466 J/g°C.

Explanation:

Given,

Q = 1120 Joules

mass = 12 grams

T₁ = 100°C

T₂ = 300°C

The specific heat for the metal can be calculated by using the formula

Q = (mass) (ΔT) (Cp)

ΔT = T₂ - T₁ = 300°C  - 100°C   = 200°C

Substituting values,

1120 = (12)(200)(Cp)

Cp = 0.466 J/g°C.

Therefore, specific heat of the metal is 0.466 J/g°C.
