Question

Calculate how many grams of nabr may be produced from 5.00 grams of solid sodium metal when combined with unlimited bromine gas.

Answer 1

The balance chemical equation for this reaction is as follow,

2 Na + Br₂ -------> 2 NaBr

According to this equation, 45.98 g when reacted with excess of Bromine produces 205.78 g of NaBr.

Now, Calculating for 5 g fo Na metal,

= (205.78 × 5) ÷ 45.98

= 22.37 g of NaBr
