Electronegativity is the tendency of an element to attract the bonded electrons towards itself. In a group, as the atomic radius increases electronegativity decreases as the outermost electron is far away from the nuclear attraction. In a period, the atomic size decreases. So, the effective nuclear charge experienced by the outermost shell increases. Therefore, across a period the electronegativity increases as the increased effective nuclear charge leads to the attraction of bonded electrons with greater ease.
Therefore the correct answer is <u>c</u>, electronegativity tends to increases across a period.
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>
<em />
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
<h3>El volumen final del sistema es 1.2L</h3>
