It is not, because the mass is being conserved and not changed.

Answer:
When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the meniscus. Measure so that the line you are reading is even with the center of the meniscus. For water and most liquids, this is the bottom of the meniscus. For mercury, take the measurement from the top of the meniscus. In either case, you are measuring based on the center of the meniscus. For a flat meniscus, make sure the liquid is level. Usually placing the container on a lab bench does the trick.
You won't be able to take an accurate reading looking up at the liquid level or down into it. Get eye level with the meniscus. You can either pick up the glassware to bring it to your level or else bend down to take measurements in situations where you're concerned with dropping the container or spilling its contents.
Use the same method to take measurements each time so that any errors you make will be consistent.

Answer:
they're losing electrolytes
Explanation:
When athletes sweat, they're losing electrolytes primarily in the form of sodium (Na+) and chloride (Cl-), so when you start to replace lost fluids, ahtletes should replace the electrolytes as well. Potassium (K+), Magnesium (Mg2+) and Calcium (Ca2+) are electrolytes also lost through sweating.
Answer:- 
Explanations:- In reduction the electrons are accepted and so they are written on the reactant side. When an atom accepts electrons then it forms anion. Chlorine has 7 valence electrons and it needs one more electron to complete it's octet. Since, dichlorine has two Cl atoms and each Cl atom needs one more electron to complete it's octet, two electrons are accepted by dichorine to make aqueous chloride ion. For balancing the equation, there would be two chloride ions as the reactant side has two chlorine atoms.

Answer: The new volume of the air in the syringe is 7.3 mL.
Explanation:
Given:
= 2.0 mL,
= 1.02 atm, 
= ?,
= 1.27 atm, 
Formula used to calculate the new volume in syringe is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the new volume of the air in the syringe is 7.3 mL.
