In the technique of recrystallization, what is the 'mother liquor'? The mother liquor is the product in its liquid form. The mother liquor is always the non-limiting reactant in the reaction. The mother liquor is the filtrate. The mother liquor always refers to ethanol.

In the technique of recrystallization "the mother liquor is the filtrate".

Option: C

Explanation:

The portion of a solution remaining over after crystallization is understood as a mother liquor. It is found in chemical reactions that include sugar refining. It is the liquid produced by filtration of the crystals. The residual liquid, once the crystals have been extracted out as the mother liquor will include a portion of the initial solution as estimated at that temperature by its solubility as well as any unfiltered contaminants. Second and third crystal crops can then be collected from the mother's liquor.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
