Niven wants to calculate the mass of mgo that is produced by burning of 28.0g of mg. what is the first step in nivens calculation?

-

The experiment Niven is doing is burning of Mg.

The first step would be finding the molar mass of MgO

Atomic mass of Mg = 24 g

Atomic mass of Oxygen = 16 g

Molar mass of MgO = 24 x 1 + 16 x 1 = 40 g

The balanced chemical equation for this reaction is

2 Mg + O2 -- > 2MgO

From the balanced equation we see that

2 Mg gives 2 MgO

2 x24 g of Mg O gives 2 x 40 g of MgO.

28g of MgO gives

= 46.66 g of MgO.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
