How many liters of space will 7.80 moles of methane gas (CH4) occupy at STP
Alchen [17]

Answer:

V CH4(g) = 190.6 L

Explanation:

assuming ideal gas:

  • PV = RTn

∴ STP: T =298 K and P = 1 atm

∴ R = 0.082 atm.L/K.mol

∴ moles (n) = 7.80 mol CH4(g)

∴ Volume CH4(g) = ?

⇒ V = RTn/P

⇒ V CH4(g) = ((0.082 atm.L/K.mol)×(298 K)×(7.80 mol)) / (1 atm)

⇒ V CH4(g) = 190.6 L

Write the equilibrium expression showing the dissociation of Ca(OH)2 in water. (Omit states-of-matter from your answer. )
Monica [59]

Answer:

Ca(OH)2 --> Ca2+ + 2OH-

Explanation:

Calcium hydroxide is sparingly soluble in water. It dissociates to give the following:

The net ionic equation :

Ca(OH)2 + H2O --> Ca2+ + 2OH- + H2O

Since, H2O doesn't affect the overall reaction, therefore;

Ca(OH)2 --> Ca2+ + 2OH
