Answer:
A ) 1, 2 and 3
Explanation:
1 ) is correct because,
K donates 1 electron
F gain 1 electron from K.
If donating and gaining of electrons takes place between two electron, then type of compound formed is ionic.
2 ) is correct because,
K + F -----> KF
3 ) is correct because,
KF is soluble in cold water; very soluble in hot water.
Answer:
i think its 10 miles per hour
First, let's find the number of moles of ammonium nitrite.
0.5 mol/L * 1.20 L = 0.6 mol
The decomposition reaction is
NH₄NO₂ → N₂ + 2 H₂O
Let's calculate the amount of N₂ gas produced.
0.6 mol * 1 mol N₂/1 mol NH₄NO₂ = 0.6 mol N₂
Then, let's compute P through the ideal gas equation:
P = nRT/V
P = (0.6)(0.0821 L-atm/mol-K)(25+273 K)/10 L
<em>P = 1.47 atm</em>
Wouldn't it be just dubble the amount witch would be 300.0g water
