Answer:
T = -28.2 °C
Solution:
Data Given;
P = 1820 mmHg = 2.39 atm
V = 5.12 L
m = 19.4 g
R = 0.0821 atm.L.mol⁻¹.K⁻¹
Calculating moles,
n = 19.4 g ÷ 32 g.mol⁻¹
n = 0.606 mol
Assuming that the oxygen gas is acting perfectly, then according to Ideal Gas Equation,
P V = n R T
Solving for T,
T = P V / n R
Putting values,
T = (2.39 atm × 5.12 L) ÷ (0.606 mol × 0.0821 atm.L.mol⁻¹.K⁻¹)
T = 244.7 K
Or,
T = -28.2 °C
Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. ... When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green.
When phenol is heated with zinc dust benzene is obtained.
The only difference is that ozone is made up of three oxygen atoms, while the stuff we breathe oxygen is made up of only two atoms.
