Titration is a technique for determining unknown molarity of acid by adding a base of know malarkey to a known volume of acid
The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration. Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. The goal of titration is to identify the equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, which is a key analytical chemistry technique also known as volumetric analysis. The stoichiometry of the reactants determines how many reactants have been mixed at the equivalence point.

<h2><u>Answer:</u></h2>
A nonpartisan iota of Nitrogen has a mass of 18. There are 7 protons in the core of this iota. What number of neutrons, complete electrons, and valence electrons are available
Nitrogen 15 has a nuclear mass of 15. The mass number is # protons in addition to # of neutrons, so for N-15 mass is 15 and the protons are dependably 7 so there must be 15-7=8 neutrons. N-15 has 7 electrons since it has 7 protons and p = e.
Answer:
In 12.6g of there are 0.29 moles of and molecules of
Explanation:
First you should find the molar mass of the :
Then you should write the conversion factor using the molar mass:
So, there are 0.29 moles of in 12.6g of .
Finally to find the number of molecules, you should use the Avogadro´s number:
There are moles of in 12.6g of
<span>Silver nitrate (AgNO3) is a colorless solution . when we add silver nitrate to dilute HCl we get a white precipitate of silver chloride
But here as you employed a concentrated hydrochloric acid initially the precipitate of silver chloride is formed but it immediately dissolves in HCl leaving a colour less solution
it all depends on the amount of HCl taken and amount of silver nitrate added to it
if we add equimolar quantities of both we will get a clear solution
if we add excess of silver nitrate we will get a small amount of white precipitate
AgNO3(solution) + Conc.HCl ----------> AgCl(Solution) + HNO3
AgNO3 (excess) + Conc.HCl --------> AgCl(Small white ppt) + HNO3</span>
Always is a pretty absolute word and since nothing is impossible I would say no. However, usually for the most part technology does follow science.
If you want to develop a technology, you need to understand the physical principals behind it such as dynamics,material behavior, etc. this all requires knowledge physics and chemistry.

Physicists during the 1800's were studying the theory to magnetic and electric fields and their interactions way before they were devices to create/observe this phenomenon esp. according to their theory.</span><span>
