Answer:
Kinetic Energy
Explanation:
Kinetic energy is the energy inside moving objects of things.
Answer: Volume of the 1M EtOH and water should be 0.75 ml and 9.25 ml respectively to obtain the working concentration.
Explanation:
According to the dilution law,

where,
= molarity of stock solution = 1M
= volume of stock solution = ?
= molarity of diluted solution = 0.075 M (1mM=0.001M)
= volume of diluted solution = 10 ml
Putting in the values we get:


Thus 0.75 ml of 1M EtOH is taken and (10-0.75)ml = 9.25 ml of water is added to make the volume 10ml.
Therefore, volume of the 1M EtOH and water should be 0.75 ml and 9.25 ml respectively to obtain the working concentration
The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.
<h3>What generates a magnetic field?</h3>
When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.
In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.

Answer:
False
Explanation:
Laboratory synthesis of aspirin is done by the acetylation of salicylic acid with the help of acetic anhydride .
As , the acid anhydride is very sensitive to moisture , as it can hydrolyze into two molecules of acids,
Hence , the reaction involving acid anhydride are conducted in anhydrous solvents .
Hence ,
if water is present in the glassware then , some of the acetic anhydride is wasted , Which in turns reduces the yield than that expected .
Answer: 
Explanation:
Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol
.
, energy is absorbed while forming of the lattice
, energy is release while forming of the lattice

One mole of sodium ion when combines with one mole chloride ion release 786 kJ of energy.
