Ionic compounds are substances that are made up of ions. There is no ionic formula as carbon and oxygen do not form an ionic compound.

Ionic compounds are compounds that have two differently charged species that bind together. The positive metal species binds to the negative nonmetal species.

Carbon and oxygen both are nonmetals and cannot form a bond as nonmetals gain electrons and metals donates electrons for the bond formation.

Therefore, no ionic compound is present for carbon and oxygen.

If the self ionization reaction is endothermic then it will shift on right side from equilibrium if we increase the temperature.

Endothermic reactions are those reactions in which heat or energy is absorbed by the reactants for the formation of product.

If the self ionization reaction is endothermic in nature then in this condition at the equilibrium if we increases the temperature then the formation of ions increases as a result of the shift of the reaction towards the right side.

Hence, by increasing the temperature we can predict whether the reaction is endothermic or not.

Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.

A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.

A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.

Therefore, hydrogen molecules cannot form a double bond.

When more products or reactants are added to a reaction that is in equilibrium, the equilibrium will shift so as to annul the effects of adding the products/reactants.

It states that when a reaction is in equilibrium and one of the constraints that affect the rates of chemical reactions is applied, the equilibrium will shift accordingly so as to annul the effects of the added constraint.

Thus, if more products are added, the equilibrium will shift to produce more reactants. If more reactants are added, the equilibrium will shift to produce more products.

Hence, what will happen to the equilibrium position depends on whether CHO2– is a reactant or product.

Explanation:

I am not sure if your teacher expects you to just find specific heat yourself, but if they do answer it using as below:

Quick search shows aluminium specific heat is 0.90 J/gC.

use formula: q = mcΔT (q = heat, m= mass, c= specific heat, ΔT is temperature change)

q = mcΔT

q/(mc) = ΔT

32.3/(0.87 x 0.90) = ΔT

ΔT = 41.25 C

Mole fraction is the ratio of the constituent moles to the total constituents. The mole fraction of sodium chloride is 0.0443.

A mole fraction is the proportion of the moles of the component in a total component present.

In 100 gm of solution 13.0 5 means, there is 13.0 gm of sodium chloride present. The mass of water is calculated as,

100 - 13.0 = 87.0 gm

Moles of sodium chloride is calculated as:

[tex]\begin{aligned} \rm moles &= \rm \dfrac{mass}{molar\; mass} \\\\&= \dfrac{13}{58}\\\\&= 0.224 \;\rm moles\end{aligned}[/tex]

Moles of water are calculated as:

[tex]\begin{aligned} \rm moles &= \rm \dfrac{mass}{molar\; mass} \\\\&= \dfrac{87}{18}\\\\&= 4.83\;\rm moles\end{aligned}[/tex]

Now, moles fraction is calculated by dividing moles of sodium chloride by total moles as,

[tex]\begin{aligned} \text{Mole fraction of NaCl} &= \dfrac{0.224}{0.224 + 4.83}\\\\&= 0.0443\end{aligned}[/tex]

Therefore, the mole fraction of sodium chloride is 0.0443.

Assuming that both cases describe hydrogen‑like atoms with one electron, More energy is emitted or absorbed for case 2. The correct option is D.

The energy of the electron decreases as it changes levels, and emission of photons happens in the atom.

With the electron moving from a higher to a lower energy level, the photon is emitted. The photon's energy is the same as the energy lost by an electron moving to a lower energy level.

Thus, the correct option is D, More energy is emitted or absorbed for case 2.
