Answer:
RbI<RbBr<RbCl<RbF
Explanation:
As stated in the question, the latice energy depends on the relative size of the ions. When the action size is constant as in the question, the lattice energy now depends on the relative of the anions. The order of increase in ionic sizes among the halide ions is fluoride<Chloride<Bromide<Iodide. This order of increasing size means that the lattice energy will decrease accordingly as shown in the answer.
Answer: D
Explanation: Keeping the pressure constant and increasing the temperature.
<span>grape juice
pOH = -log[1.4*10⁻¹⁰]</span>≈9.6
pH=14-pOH=14-9.6=4.4
orange juce
pH= -log[1.8*10⁻⁴]=3.7
Orange juice has lower pH, so it is more acidic.
Answer:
The answer is 1.54molar mass.
Respuesta:
2 m
Explicación:
Paso 1: Información provista
- Volumen inicial (V₁): 100 mL
- Concentración inicial (C₁): 4 m
- Volumen final (V₂): 200 mL
- Concentración final (C₂): ?
Paso 2: Calcular la concentración de la solución final
Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 4 m × 100 mL / 200 mL = 2 m
