B) Dalton's law
Explanation:
Dalton's law of total pressure of mixture of gases is the sum of the partial pressure of the gases that makes them up.
The law states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
Pt = P1 + P2 + P3 .....Pn
where:
Pt is the total pressure of gas mixture
P1,P2,P3,...Pn = partial pressure of gases 1,2,3...n respectively
A partial pressure is the pressure a gas would exert if it occupies the volume of a container alone

Answer:
See explanation
Explanation:
A balanced chemical reaction equation has the same number of atoms of each element on both sides of the reaction equation.
Hence, for the reaction between KOH and H2SO4, the balanced chemical reaction equation is;
H2SO4(aq) + 2KOH(aq) ---------> K2SO4(aq) + 2H2O(l)
Complete ionic equation;
2H^+(aq) + SO4^2-(aq) + 2K^+(aq) +2OH^-(aq) -------> SO4^2-(aq) + 2K^+(aq) + 2H2O(l)
Net ionic equation;
2H^+(aq) + 2OH^-(aq) -------> 2H2O(l)
Answer:
17 ppm
Explanation:
Paso 1: Información brindada
Masa de soluto: 0.025 g
Volumen de solución: 1.5 L
Paso 2: Convertir la masa de soluto a miligramos
Usaremos el factor de conversión 1 g = 10³ mg.
0.025 g × (10³ mg/1 g) = 25 mg
Paso 3: Calcular las partes por millon (ppm) del soluto
Usaremos la siguiente expresión.
ppm = mg de soluto / litros de solución
ppm = 25 mg / 1.5 L
ppm = 17 mg/L
