Answer:
0.0059mol
Explanation:
From the ideal gas equation
PV=nRT
P=Pressure
V=Volume
R=Ideal gas constant
T=Temperature
n=number of mole
P=745mmHg
760mmHg=1atm
745mmHg=0.98atm
volume of water displaced=volume of hydrogen produced=145ml=0.145L
R=0.082Latm/mol/K
T=22°C=273+22=293K
no of mole=PV/RT
=0.98×0.145/0.082×293
=0.1421/24.026
=0.0059mol

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
Answer:
I will!
Explanation:
Friends are always a good thing to have.
The amount of matter in an object is said to be its mass. The SI base unit of mass is kilograms i.e. .
The mass of the object = (given)
For converting lbs to kg:
So,
Hence, the mass of object in kilograms is .
The correct answer would be A) A soccer ball passed between two players because the ball is in motion.
