Consider the following reaction: 2 H2(g) + 2 NO(g) → 2 H2O(g) + N2(g) If the concentration of NO changed from 0.100 M to 0.025 M in the first 15 minutes of the reaction, what is the average rate of the reaction during this time interval?

The average rate of the reaction during this time interval is, 0.005 M/s

Explanation:

The given chemical reaction is:

The expression will be:

where,

= final concentration of = 0.025 M

= initial concentration of = 0.100 M

= final time = 15 minutes

= initial time = 0 minutes

Putting values in above equation, we get:

Hence, the average rate of the reaction during this time interval is, 0.005 M/s

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
