Answer:
The resulting pH will be greater than 7 because potassium hydroxide is less concentrated than the hydrochloric acid.
Explanation:
hope this helped!
Answer: condenstation.
Justification:
The polymerization by condensation is a well know chemical reaction in which two monomers ("small" molecules), each with (at least) two functional groups, combine and relase water as by-product. Actually, even if the by-product released is not water, yet the reaction is called condenstation, since the mechanism is basically the same.
An example of such reaction is the manufacturing of nylon 6,6, which is produced from adipic acid and 1,6-diamine hexane:
HOOC - [CH₂]₄ - COOH + nH₂N - [CH₂]₆ - NH₂ → - nylon - + nH₂O
I omitted the formula of nylon because it is large, and that is not the core of the question but the fact the kind of reaction: two molecules combine to form is a larger molecule, and water is released
Explanation:
As we know that density is the amount of mass present in a liter of solution.
Mathematically, density =
As it is given that density of water is 1 g/ml and volume is 175 mL. So, mass of water will be calculated as follows.
density =
1 g/ml =
mass = 175 g
It is known that 18 g of water contains 1 mole of water. Hence, number of moles present in 175 g of water will be calculated as follows.
No. of moles =
=
= 9.72 mol
This means that we have 9.72 moles of ethanol also.
Hence, volume of ethanol present in 175 ml of water will be as follows.
No. of moles of ethanol =
9.72 mol =
Volume = 566.69 ml
Thus, we can conclude that 566.69 ml volume of ethanol contains the same number of molecules as are present in 175 ml of .
Answer:
Explanation:
Hello,
This problem could be solved in terms of normality as follows:
- The normality of phosphoric acid (triporitic) is:
Thus, the normality of barium hydroxide turns out:
Finally, the molarity:
Best regards.
Temporary hardness can be dealt with using boiling water(Calcium hydrogen carbonate) but Permanent won't so you need to use washing soda instead(sodium carbonate) or Ion exchange resin
