I'll do A for you. They are all double displacement reactions. So recall: AB+CD--> CB+AD . Also, knowing the charges will help and make this so easy.
Answer:
C) 5 moles of Argon (Ar)
Explanation:
5mol Na x 22.990g Na/ 1 mol Na = 114.95g Na
5mol P x 30.974g P/ 1 mol P = 154.87g P
5mol Ar x 39.948g Ar/ 1 mol Ar = 199.74g Ar
Therefore Ar has the greatesr mass.

Answer:
Chlorine has strong inter molecular forces than iodine
Explanation:
Answer:
Magnesium oxide
Explanation:
When magnesium reacts with oxygen, the magnesium atoms donate electrons to O2 molecules and thereby reduce the oxygen. Magnesium therefore acts as a reducing agent in this reaction. The O2 molecules, on the other hand, gain electrons from magnesium atoms and thereby oxidize the magnesium.
