This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
I looked this up but hope it helps!
The final temperature = -145.24K or 127°C.
According to the data given,
T1= 88°C = 361.15K
V1= 9.6 L
V2= 3.4 L
T2= ?
We know that, according to Charles's law,
T1/V1=T2/V2
T2= T1*V2/V1
T2= 127°C or -145.24K
The final temperature = -145.24K or 127°C
<h3>What does Charles law state?</h3>
According to Charles' law, when the pressure is held constant, the volume of a given amount of gas is precisely proportional to its temperature on the kelvin scale.
<h3>What connection exists between volume and temperature?</h3>
- In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.
- When a constant mass of gas is cooled, its volume decreases, and when the temperature is elevated, its volume grows.
<h3>What are the applications of Charles law?</h3>
- A hot air balloon drifting through the air is an illustration of Charles Law in action.
- The air within the balloon is heated by a torch, which causes the air molecules to move more quickly and disperse.
- This causes the air inside the balloon to be less dense than the air outside, which causes the balloon to float.

When the work is being done, it is likely that there is an energy being enforced and when the energy is being enforced, it is likely that the energy present is being transferred in order for the work to be able to be able to be exterted upon
Answer:
a. N₂O₅ + H₂O ⇒ 2 HNO₃ (pentóxido de dinitrógeno + agua ⇒ ácido nítrico)
b. Na₂O + H₂O ⇒ 2 NaOH (óxido de sodio + agua ⇒ hidróxido de sodio)
Explanation:
Tenemos que balancear, por el método de tanteo, las siguientes ecuaciones químicas.
a. En la primera reacción, el pentóxido de dinitrógeno reacciona con agua para formar ácido nítrico. Es una reacción de síntesis o combinación.
N₂O₅ + H₂O ⇒ HNO₃
Podremos obtener la ecuación balanceada si multiplicamos HNO₃ por 2.
N₂O₅ + H₂O ⇒ 2 HNO₃
b. En la segunda reacción, óxido de sodio reacciona con agua para formar hidróxido de sodio. Es una reacción de síntesis o combinación.
Na₂O + H₂O ⇒ NaOH
Podremos obtener la ecuación balanceada si multiplicamos NaOH por 2.
Na₂O + H₂O ⇒ 2 NaOH
