Answer: Thus the volume of the balloon at that new location is 
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 0.995 atm
= final pressure of gas = 0.720 atm
= initial volume of gas = 
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:


Thus the volume of the balloon at that new location is 
Whether water is frozen, in a gaseous state, or is a liquid, it is still H2O. So the chemical composition does stay the same.
Answer:
Elements in the same vertical column on the periodic table will have similar chemical properties and behave similarly in chemical reactions. These vertical columns can also be called groups/families.

i know this i just had this assingment 10 min ago and i had it right
Answer:
2 electrons from magnesium (Mg) is transferred to oxygen (O2) to form Mg2+ and O2-
which combines by strong electrostatic force to form MgO
the equation is
2Mg + O2 -> 2MgO
