Answer:
The water molecules turned into gas called<em> "water vapor"</em> and are now part of the air.
Explanation:
The "drops of water" are actually made up of<u> water molecules.</u> Under <em>heat,</em> they change their phase from liquid to gas. This means that the water molecules <em>move faster. </em>Such movement allows the molecules to escape into the atmosphere as gas. Such gaseous state of water is called "water vapor" <em>(transparent in color).</em>
The client consultation must have taken time that the drops of water evaporated when Jayden came back.
Aside from evaporation, water vapor may also be produced through the process called "sublimation." This happens when<em> ice directly turns into gas without becoming a liquid.</em>
So, this explains the answer.
Answer:
The molarity of the solution is 0,99M
Explanation:
We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)
Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g
58, 5 g-----1 mol NaCl
145 g ---------x= (145 g x 1 mol NaCl)/58, 5 g= 2,48 mol NaCl
2,5 L solution------ 2, 48 mol NaCl
1 L solution------x= (1 L solutionx 2, 48 mol NaCl)/2,5L solution
x=0,99 mol NaCl---> The solution is 0,99 molar (0,99 M)

H--F is the mist polar because there is a bigger difference between the electronegativity numbers of fluorine and hydrogen than with the others. The periodic trend for electronegativity is diagonally with cesium being the lowest and flourine being the highest
The percent yield represents that the efficiency of a reaction.
It represents how much times we have achieved the target yield from a particular reaction
The relation between theoretical yield, measured yield and percent yield is
percent yield =
for the given reaction
percent yield = %
Answer: 94.23%
