Answer:
There is 1.9 moles of oxygen gas in the cylinder.
Explanation:
Pressure of the oxygen gas = P = 1.7 atm
Volume of the oxygen gas = V = 26.5 L
Temperature of the oxygen gas = T = 295 K
Moles of oxygen gas = n
Using ideal gas equation ;
![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
![n=\frac{PV}{RT}=\frac{1.7 atm\times 26.5 L}{0.0821 atm L/mol K\times 295 K}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BPV%7D%7BRT%7D%3D%5Cfrac%7B1.7%20atm%5Ctimes%2026.5%20L%7D%7B0.0821%20atm%20L%2Fmol%20K%5Ctimes%20295%20K%7D)
n = 1.8600 mol ≈ 1.9 mol
There is 1.9 moles of oxygen gas in the cylinder.
ANSWERS:
Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
