Answer :
According to the law of conservation of mass, the mass of reactants must be equal to the mass of products.
The balanced chemical reaction is,
As we know that the molar mass of magnesium is 24 g/mole, the molar mass of 
is 32 g/mole and the molar mass of magnesium oxide is 40 g/mole.
From the given balanced reaction, we conclude that
As, 1 mole of magnesium react 
mole of oxygen to give 1 mole of magnesium oxide.
So, the mass of Mg is 24 g, the mass of 
and the mass of MgO is 40 g.
That means 24 g of Mg react with 16 g to give 40 g of MgO.

Answer:
The answer to your question is: CO2
Explanation:
The information given is correct, Covalent bonds occur when atoms share one or more pairs of electrons, but also, covalent bonds occur with nonmetals, then,
a.NaCl This elements form an ionic bond, so this option is incorrect.
b.Cl2 Here there are two non metals but the form one single covalent bond, so this option is incorrect.
c.CO2 Carbon dioxide forms 2 double covalent bonds.
d.NH3 ammonium only forms single covalent bonds
Answer:
Where the chart pls I can answer
Explanation:
Format Method - Writing the symbol of the cation and then the anion. Add whatever subscripts in order to balance the charges.
Crisscross Method - The numerical value of the charge of each ion is crossed over and becomes the subscripts for the other ion.
