If the length of a string increases 2 times but the mass of the string remains constant, the original density will be multiplied by a factor mathematically given as
v=1.414 times
<h3>Will the new density of the string equal the original density multiplied by what factor?</h3>
Generally, the equation for the volume is mathematically given as
v = sqt(TL/m)
Where
density = mass/length
Therefore


In conclusion,v ratio will give us
v=1.414 times

Answer:

Explanation:
We know that , the reaction between NaOH and HCl is given as

Form the above reaction we can say that
Number of moles of HCl =Number of moles of NaOH

Therefore



Therefore the numbers of moles needed of HCl wil be 
Answer:
Antoine Lavoisier.
Explanation:
I would say that it's the 18th century French chemist Lavoisier. He can arguably be called the father of modern chemistry. He proved the law of the conservation of mass and had a large part in developing the scientific method.
The highest sequence for this shell is the number 2, preceding both the s and p in the diagram. This means that the outermost shell is the second level shell. In this shell, there are 7 electrons, 2 in the 2s orbital and 5 in the 2p orbital.
As a side note (not sure if this is a typo), the electron structure for fluorine begins with a 1s2, not a 1s1.
