Answer:
What are some things that might happen that can change our air so that it is not health for plants?
Explanation:
Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy. Air pollutants that are first deposited on the soil, such as heavy metals, first affect the functioning of roots and interfere with soil resource capture by the plant.
Answer:
Sodium oxide is the product
Explanation:
4Na+O2->2Na2O
The word for horizontal rows of the periodic table is a period
Answer:
0.1440M
Explanation:
Let''s bring out the parameters we were given;
Rate constant = 8.74 x 10^-4s^-1
Initial Concentration [A]o = 0.330M
Final concentration [A]= ?
Time = 800s
The reaction is a first order reaction, due to the unit of the rate constant. In first order reactions, the reaction rate is directly proportional to the reactant concentration and the units of first order rate constants are 1/sec.
Formular relating these parameters is given as;
ln[A] = ln[A]o − kt
Making [A] subject of interest, we have;
ln[A] = ln[A]o − kt
ln[A] = ln(0.330) - ( 8.74 x 10^-4 * 800)
In[A] = - 1.1086 - (6992 x 10^-4)
ln[A] = -1.8079
[A] = 0.1440M
