Hi,
Two sodium atoms are needed to create an ionic bond with sulfur.
Answer:
See explanation
Explanation:
Hello there!
In this case, since the the concentrations are not given, and not even the Ksp, we can solve this problem by setting up the chemical equation, the equilibrium constant expression and the ICE table only:
Next, the equilibrium expression according to the produced aqueous species as the solid silver chloride is not involved in there:
And therefore, the ICE table, in which x stands for the molar solubility of the silver chloride:
I - 0 0
C - +x +x
E - x x
Which leads to the following modified equilibrium expression:
Unfortunately, values were not given, and they cannot be arbitrarily assigned or assumed.

Answer:
47.27 atm
Explanation:
For this problem, you will use PV=nRT as your equation
P = being found
V= 40 L
n = 78.13 moles
R = 0.082
T= 295.15 K
The set up is:
p (40.0)= (0.082)(78.13)(295.15)
40p=1890.9
p = 47.27 atm
This is false. They were both chemists and they made many discoveries such as realizing that charcoal and diamond are different forms of the same element and proposing an atomic theory, but they never tried to turn diamonds to gold.
You calculate the mass using dimensional analysis.
We are given with
The weight of the chain per unit length which is 2.16 kg/m
We are also given with the needed length of the chain which is 7.0 m
Therefore, the mass of the chain is
7.0 m x 2.16 kg / m = mass of the chain in kg<span />
