The answer is 3.
Explanation:
It’s the last number and it can’t be 9 because then it would be 48.9 and no 3.
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>
Physical: food turns into our feces
Chemical: water turns into urine, food digest,
(honestly I think those are the answers)
This is a guess, but I think it could be the lack of limiting factors.
The answer is (2) gains 12 moles of electrons. In every chemical reaction, the electrons will not be destroyed or created, it will only transfer. So the Al loses electrons, the oxygen needs to gain the same amount of electrons.
