Answer:
Mass of liquid unknown liquid = 10.4 g
Explanation:
Volume of liquid = 15 mL
Mass of liquid + graduated cylinder = 55.2 g
Mass of graduated cylinder = 44.8 g
Mass of unknown liquid = ?
Solution:
Mass of unknown liquid is calculated by subtracting the graduated cylinder mass from combined mass of liquid and graduated cylinder.
Mass of liquid = (Mass of liquid + graduated cylinder) - (Mass of graduated cylinder )
Mass of liquid = 55.2 g - 44.8 g
Mass of liquid = 10.4 g
So the mass of unknown liquid is 10.4 g.
True, if this is a true or false question.
Answer: Lionfish, which are covered in venomous spines, are such successful invaders because they can tolerate a variety of habitats and they reproduce at alarming rates.

Answer:
The proton remains the same.
Explanation:
Oxidation is simply defined as the loss of electron(s) during a chemical reaction either by an atom, molecule or ion.
Oxidation is strictly on the transfer of electron(s) and not proton.
A metal that undergoes oxidation still has its protons intact otherwise it will not be called the ion of the metal since atomic number is called the proton number.
Sodium (Na) undergoes oxidation as follow:
Na —> Na+ + e-
Na is called sodium metal.
Na+ is called sodium ion.
Na has 11 electrons and 11 protons
Na+ has 10 electrons and 11 protons
From the above illustration, we can see that the protons of Na and Na+ are the same why their electrons differ because Na+ indicates that 1 electron has been loss or transferred.
