Explicación:
Utilizamos la relación de moles para calcular la presión parcial. El número total de moles es 0.2 + 0.2 + 0.1 = 0.5 moles
Ahora, sabemos que la fracción molar del gas argón es 0.2/0.5
La presión parcial se determina así. Para calcular esto, simplemente multiplicamos el número de moles por la presión total.
0.2/0.5 * 5 = 1.0/0.5 = 2.00atm

More information is needed, but in general, a polyatomic ion consists of multiple atoms bonded together, often with instability that affects their bonding patterns.
The correct equation is (C) H3O+(aq) + C2H3O2−(aq) -> HC2H3O2(aq) + H2O(l). A buffer system is composed of a weak acid and its corresponding salt, effectively stabilizing the pH levels within a solution. The buffer works by adjusting the concentrations of the conjugate acid and base, maintaining the pH constant.
The solution to your inquiry is: c = a + b - d. In the chemical equation aA + bB → cC + dD, c may take any value from 1 to however many are needed for the equation to maintain its balance. For instance, if we consider c + d = a + b, we can express c as a + b - d. If we assign values a = 1; b = 3, and d = 2, then c equals 1 + 3 - 2, resulting in c = 2, and so forth.
