Answer:
The value of for this reaction at 1200 K is 4.066.
Explanation:
Partial pressure of water vapor at equilibrium =
Partial pressure of hydrogen gas at equilibrium =
Total pressure of the system at equilibrium P = 36.3 Torr
Applying Dalton's law of partial pressure to determine the partial pressure of hydrogen gas at equilibrium:
The expression of is given by:
The value of for this reaction at 1200 K is 4.066.
Answer: B) explanation of why the pesticide is toxic to organisms.
Explanation:
Pesticide is a chemical or biological substance which is required to kill the population of pests and which are harmful and affecting the life cycle of the plants.
The structure of pesticide is required to be known so as to get information of the chemical or biological agent present in these pesticides. This can help in determining the fact that which ion or molecules directly cause harm to the body of pests by releasing the toxicity.
Answer:
Kc = 32.3
Explanation:
To calculate the Kc, it's the ratio of products over reactants (each raised to their respective stoichiometric coefficient). In this case:
Answer:
12.5g
Explanation:
1. Percentage of solution = 5.
2. Mass of solution = 250g.
3. = Mass of solute / 250 x 100.
4. = 5 x 250 / 100.
5. = 12.5g.
