Answer : 5.405 moles of 
are equivalent to 97.3 grams of
Solution : Given,
Mass of = 97.3 g
Molar mass of = 18 g/mole
Formula used :
or,
Now put all the given values in this formula, we get the moles of
Therefore, 5.405 moles of are equivalent to 97.3 grams of
Answer:
Gravitational potential energy
Explanation:
it is
Answer:
A. Molarity will increase .
Explanation:
Molarity = moles of solute per litre of solution
= moles of solute / volume of solution
If evaporation occurs , volume of solution decreases and moles of solute remains constant . Hence denominator decreases and numerator remains constant .
Hence the molarity increases .
Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever if two solutions are mixed, then if there is any color change, or evolution of any vapors, bubbles or gas formation or if there is any formation of a color or white precipitate confirms that the occurrence of a chemical reaction.
If nothing happens said above then it is said that there is no chemical reaction occurs.
Here in the event 1 a clear liquid in one beaker poured into clear liquid in beaker 2 then there is a formation of orange liquid, which means there is a formation of a new colored liquid confirms that the chemical reaction occurred.
