Answer:
D. 8.3 x 10-4
Explanation:
Hello!
In this case, since the rate law is written solving for the rate constant as:
Thus, we plug the rate and concentrations to obtain:
Therefore, the answer would be D. 8.3 x 10-4
Best regards!
Answer:
Neither
Explanation:
Kyle would gain potential energy and lose kinetic energy
I believe the major periodic trends include; electronegativity, ionization energy, electron affinity, atomic radius, melting point, and the metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's property.
Answer:
S = 1,75x10⁻⁴M
Explanation:
It is possible to answer this question using Henry's law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The formula is:
S = k×Pi
Where S is solubility, K is Henry's constant and Pi is partial pressure.
At sea level, Pi of O₂ is:
1atm×0,209 = 0,209 atm. Replacing:
2,67x10⁻⁴M = k×0,209atm
k = 1,28x10⁻³M/atm
At 12,000ft Pi of O₂ is:
0,657atm×0,209 = 0,137 atm. Replacing:
S = 1,28x10⁻³M/atm×0,137atm
<em>S = 1,75x10⁻⁴M</em>
