Answer : The precipitate will not be formed when these solutions are mixed.
Explanation :
The chemical equation for the reaction of calcium chloride and lithium sulfate follows:
We are given:
Concentration of calcium ion =
Concentration of sulfate ion =
The salt produced is calcium sulfate.
The equation follows:
The expression of (ionic product) for above equation follows:
Putting values of the concentrations in above expression, we get:
There are 3 conditions:
- When ; the reaction is product favored. (No precipitation)
- When ; the reaction is reactant favored. (Precipitation)
- When ; the reaction is in equilibrium. (Sparingly soluble)
As, the . The above reaction is product favored. This means that no salt or precipitate will be formed.
Hence, the precipitate will not be formed when these solutions are mixed.
Answer:
the 4s subshell is lower in energy than the 3d subshell
Explanation:
In the element number 24 which is chromium
the electronic configuration should be according to Aufbau principle
will be =
but in reality it is =
The 6 electrons in the outermost shell will be divided as 5 in 3d subshell and 1 in 4s shell, because half filled orbital will be more stable than .
Answer : The concentration to a mole fraction in parts per billion (ppb) is, 350 ppb
Explanation :
As we are given that the concentration of chloroform is, .
Now we have to convert it into parts per billion (ppb).
As we know that,
and,
So,
Thus, the concentration to a mole fraction in parts per billion (ppb) is, 350 ppb
Answer:
Lithium and Chlorine and oxygen and Bromine are likely to form ionic compound.
Explanation:
Ionic compounds allows one or more electrons to be transferred from metals to non metals
Lithium and Chlorine will form Lithium Chloride (LiCL)
Oxygen and Bromine will form Bromine dioxide, because of two electrons from oxygen are transferred.
