Answer: Volume is 0.466 ml. Maybe in this case it is safer to round downward.
Explanation: V = 14.0 mg / 30 mg/mL = 0.466.. ml
SO2 is not likely to be ionic.
An ionic bond is most commonly formed between a metal and a non-metal.
K (potassium) and Br (bromine) are a metal and non-metal pair.
Al (aluminum) and Cl (chlorine) are a metal and non-metal pair.
S (sulfur) and O (oxygen) are both non-metals, and likely formed a covalent bond instead of an ionic bond, which is common for two non-metals.
La temperatura del gas contenido en el recipiente es de -259,35 ° C
Explicación:
Para encontrar la unidad de grados en Celsius (° C) en este caso, se usa la ecuación de la ley de los gases ideales.
PV = nRT
Donde P es la presión, V es el volumen, T es la temperatura, n es el número de moles y R es la constante universal de los gases.
P = 143 kPa = 1,4113 atmósferas
V = 2,00 L
n = 2,49 mol
R = 0.08205746 atm * L / mol * K
Resolver para T sería: PV / nR
T = (1.4113 atm * 2.00 L) / (2.49 mol * 0.08205746 atm * L / mol * K)
T = 2,8226 / 0,2043
T = 13,8 K = -259,35 ° C
