Answer:
a. 1,157x10⁻⁵M/s
b. 5,787x10⁻⁶M/s
Explanation:
For the reaction:
2H₂O₂(aq) → 2H₂O(l) + O₂(g).
a. The rate law of descomposition is:
Where d[H₂O₂] is the change in concentration of H₂O₂ (between 0s and 2,16x10⁴s) is (1,000M-0,500M) and dt is (0s-2,16x10^4s). Replacing:
As this rate is = d[O₂]/dt(Rate of production of O₂), the rate of production of O₂(g) is <em>1,157x10⁻⁵M/s</em>
b. Between 2,16x10⁴s and 4,32x10⁴s, rate law is:
The rates are <em>5,787x10⁻⁶M/s</em>

Answer:
Mineral dusts are solid particles, that may become airborne depending upon their origin and the surrounding physical conditions. Lead is potential poison. It is obtained from the earth crust. The lead poisoning is a popular occupational hazard. The lead in air, when taken by the human body through respiration is responsible to cause anemia, weakness and kidney and brain damage, labored breathing and lung diseases.
Once you balance the enquation you "switch partners" of the element (negative charge to positive charge)
