A Bronsted-Lowry acid is a chemical species that donates one or more hydrogen ions in a reaction. In contrast, a Bronsted-Lowry base accepts hydrogen ions. When it donates its proton, the acid becomes its conjugate base. A more general look at the theory is as an acid as a proton donor and a base as a proton acceptor. :)

Answer:
The total pressure of three gases is 837.56 mmHg.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
PT = PA + PB
This relationship is due to the assumption that there are no attractive forces between the gases.
In this case, the total pressure can be calculated as:
PT= 2.67 mmHg + 45.69 mmHg + 789.6 mmHg
Solving:
PT= 837.56 mmHg
<em><u>The total pressure of three gases is 837.56 mmHg.</u></em>
