The theoretical yield of NH3 is 945 grams. You conducted the experiment and only produced 598 grams.
zlopas [31]

Answer:

Given theoretical yield of NH3 is 945g.

The actual yield is 598g.

What is the %yield?

Explanation:

%yield of a chemical reaction can be calculated by using the formula:

%yield=\frac{actual yield}{theoretical yield}  * 100\frac{actual yield}{theoretical yield} * 100

Substitute the given values in this formula to get the %yield.

\frac{598g}{945g} * 100\\=63.3

Hence, the %yield for the formation of ammonia is ---- 63.3.

How does the temperature of the air change with altitude?
TiliK225 [7]
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
