Hey there
Thats easy
Precipitation occurs when cations and anions in aqueous solution combine to form an insoluble ionic compound called precipitation. So, you can refer to a solubility chart or draw polar/nonpolar lewis structures, that might be helpful.
Remember water is polar so polar molecules will dissolve in water
Answer: Dinitrogen pentoxide
Explanation:
Answer:
The only balanced equation is:
2KClO₃ → 2KCl + 3O₂
Explanation:
In reactant side: 6 atoms of O, 2 atoms of Cl and 2 atoms of K
In product side: 2 atoms of K and 2 atoms of Cl + 6 atoms of O
CO + 3H₂ → CH₃OH
In reactant side: 1 C, 1 O and 6 H
In product side: 1 C, 4 H and 1 O
PCl₃ + 2Cl₂ → PCl₅
In reactant side: 1 P, 7 Cl
In product side. 1 P, 5 Cl
Mg + N₂ → Mg₃N₂
In reactant side 1 Mg and 2 N
In product side 3 Mg and 2 N
Answer : The expression for solubility constant for this reaction will be,
![K_{sp}=[Ca^{2+}]^3[PO_4^{3-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5E3%5BPO_4%5E%7B3-%7D%5D%5E2)
Explanation :
Solubility product : It is defined as the product of the concentration of the ions that present in a solution raised to the power by its stoichiometric coefficient in a solution of a salt. This takes place at equilibrium only.
The solubility product constant is represented as,
.
The dissociation of calcium phosphate is written as:

The expression for solubility constant for this reaction will be,
![K_{sp}=[Ca^{2+}]^3[PO_4^{3-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5E3%5BPO_4%5E%7B3-%7D%5D%5E2)
Due to its higher oxygen content and based on its structure dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
<h3>What is the calorific value of a fuel?</h3>
The calorific value of a fuel is the amount of heat energy released from the combustion of the fuel under standard conditions.
Dietheylene glycol, isopropanol and paraffin wax are all used as fuels.
However, due to it higher oxygen content and based on its structure, diethethylene glycol has a higher calorific value than either isopropanol or paraffin wax.
Therefore, dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
