Answer:
Explanation:
For second order reaction
dC / dt = -k C²
dC /C² = - kdt
Integrating on both sides,
[- 1/C ] = - kt + P , P is a constant .
When t =0 , C = 1.33 M
P = - 1 / 1.33
[- 1/C ] =- - kt - 1 / 1.33
When t = 8.5
[- 1/C ] = - kt - 1 / 1.33
= - 1.18 x 8.5 - 1 / 1.33
= - 10.03 - .7519
= - 10.782
C = .0927 M
= .093 M
Answer:
C) 2 H₂ + O₂ → 2 H₂O
Explanation:
4 atoms of hydrogen on reactant side
2 atoms of oxygen on reactant side
4 atoms of hydrogen on product side
2 atoms of oxygen on product side
<span>I would figure this out slowly. So the percentage would be 25 2.6 billion years ago. That would leave it at 50 percent 5.2 billion years ago. If you double that 50 percent to get 100% and double the 5.2 billion years you get 10.4 billion years. This would make the answer, the rock is 10.4 billion years old</span>
Argon atoms would not tend to make bonds with other atoms since it is classified as a noble atom which means it has a complete filled subshells. It does not have any electrons that are available for bonding. Noble gases belong to the Group 8A in the periodic table of elements. All of the elements in this group do have a complete or filled electron orbitals which makes them so stable or the s and p outer electron shells are complete with electrons. All of them follows the octet rule. Thus, they do not need any sharing or transfer of electrons from other compounds for them to be more stable.
