Answer:
The answer to your question is:
Explanation:
a)
Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.
Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.
b)
Metals are located in the left side of the periodic table
Nonmetals are located in the right side of the periodic table.
c)
Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.
Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.
ANSWER:
Physical chemistry is the branch of chemistry that deals with the physical structure of chemical compounds, the way they react with other matter and the bonds that hold their atoms together. An example of physical chemistry is nitric acid eating through wood.
One single covalent bond, hope this helps!
The balanced equation for the reaction is ;
2Zn + O2 —> 2ZnO
The stoichiometry of O2 to ZnO is 1:2
The mass of ZnO formed - 358.5 g
The number of moles formed - 358.5 g / 81.4 g/mol = 4.4 moles
Therefore number of O2 moles reacted = 4.4 moles /2 = 2.2 mol
Mass of O2 reacted = 2.2 mol x 32 g/mol = 70.4 g
