The depletion of ozone (o3) in the stratosphere has been a matter of great concern among scientists in recent years. it is believed that ozone can react with nitric oxide (no) that is discharged from the high-altitude jet plane, the sst. the reaction is o3 + no longrightarrow o2 + no2 if 0.781 g of o3 reacts with 0.589 g of no, how many grams of no2 will be produced?

0.736 g

Explanation:

To calculate the moles, we use the equation:

By Stoichiometry:

1 mole of ozone reacts with 1 mole of nitric oxide to form 1 mole of nitrogen dioxide

0.016 moles of ozone reacts with= of nitric oxide to form 0.016 mole of

Thus ozone is the limiting reagent as it limits the formation of products and nitric oxide is the excess reagent as (0.019-0.016) g= 0.003 g remains as such.

Mass of

0.736 g of will be produced.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
