Which of the following correctly illustrates the mass of reactants and products for the reaction below?

4na + o2 --> 2na2o

92 g na, 32 g o2, 108 g na2o

23 g na, 16 g o2, 124 g na2o

92 g na, 16 g o2, 124 g na2o

23.0 g na, 16 g o2, 39 g na2o

The mass of reactants and products for the reaction is this:

- 92 g Na, 32 g O₂, 124 g Na₂O

which is not a choice from the list.

Explanation:

4 moles of Na reacts with 1 mol of oxygen to produce 2 moles of sodium oxide.

Na = 23 g/m

4 moles are (4 . 23) = 92 g

O₂ = 32 g/m

It's a diatomic molecule (each O is 16 g/m)

Na₂O = 62 g/m

2 mol of sodium oxide will be (2 .62) = 124 grams

The mass of reactants and products for the reaction is this:

- 92 g Na, 32 g O₂, 124 g Na₂O

which is not a choice from the list.

it's filtration, but this is an assumption so my apologies if i got this

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
