Answer:
La difusión es un proceso físico irreversible, en el que partículas materiales se introducen en un medio que inicialmente estaba ausente de ellas aumentando la entropía del sistema conjunto formado por las partículas difundidas o soluto y el medio donde se difunden o disolvente.
Explanation:
The control group in this experiment is the one with just distilled water. It is plain so they can use it to compare the other tests against.
Answer:
The correct option is: Oxygen
Explanation:
According to the Ideal Gas Equation: P.V = n. R.T
Here, R - ideal gas constant, P - absolute pressure, V - volume, T - temperature, n - number of moles of gas.
Also, n = given mass of gas (w) ÷ molar mass of gas (M)
<u>Given</u>: P = gauge pressure + barometric pressure = 1 atm + 1 atm = 2 atm; V = 5 L; w = 13 g; R = 0.08206 L·atm·mol⁻¹·K⁻¹; T = 27 °C = 27°C + 273.15 = 300.15K (∵ 0°C = 273.15 K).
Since, P.V = n. R.T = (w ÷ M) . R.T
⇒ M = (w. R.T) ÷ (P.V) = (13g × 0.08206 L·atm·mol⁻¹·K⁻¹ × 300.15K)÷(2atm × 5 L)
⇒ M = 32 g.mol⁻¹
<u>As we know, the molar mass of oxygen gas (O₂) is 32 g.mol⁻¹.</u>
<u>Therefore, the gas is </u><u>oxygen</u><u>.</u>
