The parent base of the salt presented in this item is Al(OH)₃. Since it is a combination of Al³⁺ and OH⁻, it is a weak base. Similarly, the parent acid of the compound is H₂CO₃ which is also a weak acid being a combination of H⁺ and CO₃²⁻.
Answer:
- <u>the sum of the pressures exerted by each gas.</u>
Explanation:
The total pressure of two gases present in a container is equal to the sum of the pressures exerted by each individual gas.
That is the partial pressure law (Dalton's partial pressure law) and is a consequence of the fact that, since the gas particles are so small compared with the container, every gas in a mixture can be considered to occupy the entire volume of the container, driving to that the total pressure exerted by the mixture is equal to the sum of the partial pressures of the individual gases:
