Explanation:
When dilute sulphuric acid is added to barium chloride solution, barium sulphate is formed as a precipitate and hydrogen chloride is formed in aqueous solution.
Answer:
10.69g/cm^3 or 0.0106kg/m^3
Explanation:
10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.
0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.
So technically since you questions incomplete, the equation for measuring density is P= m/v
P= rho (density)
m= mass
v= volume

Answer:
Because the kind of compounds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.
There are 2 elements in the equation that form a product
Complete Question
You are given a solution containing a pair of enantiomers (A and B). Careful measurements show that the solution contains 98% A and 2% B. What is the enantiomeric excess?
Answer:
The value is 
Explanation:
From the question we are told that
The percentage of enantiomer A is A = 98%
The percentage of enantiomer B is B = 2%
Generally the enantiomeric excess is mathematically represented as
=> 
=>
