Combustion will cause a chemical change in paper.
This is because the carbon compounds are being oxidized into carbon dioxide and water vapour (or h2o, same thing).
Answer: D, splitting water into hydrogen and oxygen is a chemical change.
Because you are never adding more than the substances created, nor are you creating any, but should a chemical reaction take place you could see the liquid change form into a gaseous state and that would result a loss of the liquid volume.
So to wrap it all up you can’t have more liquids than what is already there but you could always lose some due to a chemical change, hence the reason it says an open flask, the chemical change would not be collected, mass would be lost
The correct name of the compound Mn3(PO4)2 is definitely the last option represented above <span>D. manganese(II) phosphate. I am pretty sure this answer will help you

Answer:
moles of water in 
of water.
Explanation:
Mass of water = 
Molar mass of water = M = 18 g/mol
Moles = n = 
So, there are moles of water in of water.
