This is an exercise in the general or combined gas law.
To start solving this exercise, we must obtain the following data:
<h3>Data:</h3>
- V₁ = 4.5 l
- T₁ = 33 °C + 273 = 306 k
- P₁ = 6.54 atm
- T₂ = 94 °C + 273 = 367 k
- V₂ = 2.3 l
- P₂ = ¿?
We use the following formula:
- P₁V₁T₂ = P₂V₂T₁ ⇒ General Formula
Where
- P₁ = Initial pressure
- V₁ = Initial volume
- T₂ = Initial temperature
- P₂ = Final pressure
- V₂ = Final volume
- T₁ = Initial temperature
We clear the general formula for the final pressure.
We solve by substituting our data in the formula:
If I raise the temperature to 94°C and decrease the volume to 2.3 liters, the pressure of the gas will be 15,346 atm.
Answer:
- An ion is a charged particle.
- Ion may consist of a single charged atom or a group of atoms that have a net charge on them.
- A negatively charged ion is called anion.
- A positively charged ion is called cation.

Answer : The volume (in mL) of 95% ethanol added would be, 1.39
Explanation :
As we are given that:
Mass of 95 % ethanol = 1.2 g
Density of 95 % ethanol = 0.86 g/mL
Formula used :
Therefore, the volume (in mL) of 95% ethanol added would be, 1.39
Answer:
A. Wax drips down the side of a lot candle.
Explanation:
The chemical change from solid to liquid. This is a combustion reaction, so carbon dioxide gas and water vapour is also produced but you can't see them
