This is the ratio of gas speeds for He to H2? O 21/2 m/s
O 2 m/s
O 1/21/2 m/s
O 1/2 m/s

The correct answer is 2 Na atoms

Explanation:

To determine the number of sodium atoms produced in this reaction, the reaction described in the question must be written out in an equation and then balanced

2NaN₃ ⇒ 2Na + 3N₂

From the equation above, it can be deduced that the number of sodium atoms produced in the reaction described in the question is 2
