Answer:
- 0.022% starch/min
Explanation:
Initial Conc. = 0.050 %
Final conc. = 0.028 %
Time = 1 min
Rate of Reaction = Rate of disappearance = Change in concentration of starch / time
Rate of disappearance = [0.028 - 0.050 ] / 1
Rate of disappearance = 0.022 / 1 = - 0.022% starch/min
The negative sign denotes that the starch is disappearing.

Hydrogen reacts with nitrogen to produce ammonia based on the following equation:
3H2 + N2 ........> 2NH3
This means that each 6 grams of hydrogen react with 28 grams of nitrogen. To know how many grams of nitrogen are required to react with 2 grams of hydrogen, we will simply do cross multiplication as follows:
mass of nitrogen = (2 x 28) / 6 = 9.334 grams
Therefore, if we have 11.3 grams of nitrogen, 9.334 grams would react with 2 grams of hydrogen.
remaining mass of nitrogen = 11.3 - 9.334 = 1.966 grams
