Answer:
1.1 M
Explanation:
The dissociation of is as follows:
Given Value for
The equation for the reaction for the formation of complex ion is :
The value of
If we combine both equation and find the overall equilibrium constant will be:
<u> </u>
If = x M
The solubility of in the solution will be:
Constructing an ICE Table; we have :
Initial (M) x 0 0
Change (M) -2 (0.0518) + 0.0518 + 0.0518
Equilibrium (M) x - 0.1156 0.0518 0.0518
Equilibrium constant;
(K) =
x = [NH₃] = 1.089 M
[NH₃] ≅ 1.1 M
2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone
Explanation:
To convert grams into moles
We have 5.00 g acetone
Heat liberated = moles heat of vapourization
=0.0861 mol x 30.3 kJ/mol
= 2.61 kJ
Therefore, 2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone
The following are heterogeneous mixture: MILK THAT IS SOLD AT THE STORE, A CAKE MIX AND MIXED NUT.
An heterogeneous mixture is one which contained many parts which can be separated out.
A smoothie is an homogeneous mixture because the juice of different fruits that are use can not be separated out.
