Calculate the mass of sodium azide (2nan3) required to decompose and produce 1.20 moles of nitrogen.

here is the balanced equation, 2nan3 -> 2na + 3n2

, will mark brainliest for best answer!

The answer to your question is:  40.8 g of NaN₃

Step-by-step explanation:

NaN₃ mass = ?

nitrogen = 1.2 moles

Equation

                           2NaN₃      ⇒ 2Na  +  3N2

                          2 moles of NaN₃     3 moles of N₂

                           x                             1.2 moles of N₂

                          x = (1.2 x 2) / 3

                          x = 2.4/ 3

                         x = 0.8 moles of NaN₃

MW NaN₃ = 23 + 28

                = 51 g

                         51 g of NaN₃ 1 mol

                         x                     0.8 mol

                         x = (0.8 x 51) / 1

                        x = 40.8 g of NaN₃

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
