<span>Kylee will have the best treatment of a residential program that removes her from her current living situation, followed up with support groups to offer accountability. She want to change but her parents are mad at her that they wanted her to be clean at least 1 year. A residential program will help her and other people, who are in the same situation, to change themselves and they will get support from the organizers of the program. </span>
Answer:
Reaction is shifting left toward reactant side
Explanation:
4CuO(s) + CH₄(g) <=?=> CO₂(g) + Cu(s) + 2H₂O(g)
--------- 0.22M 0.67M ------- 1.30M
Qc = [O₂(g)][H₂O(l)]²/[CH₄(g)] = (0.67)(1.30)²/(0.22) =5.12
Kc = 1.1 < Qc = 5.12 => Reaction is shifting LEFT and reactant concentrations are increasing with product concentrations decreasing. Qc will be decreasing and final Kc value will be lower than original Qc upon reaching equilibrium stability.

FYI Note => For reaction mixtures the following is a good guide to reaction response to applied system stress. Note the conclusion follows the direction the inequality symbol is pointing.
Kc < Qc => Rxn system is shifting Left
Kc = Qc => Rxn system is at equilibrium
Kc > Qc => Rxn system is shifting Right
Answer:
4.76×10¯⁵ cm
Explanation:
We'll begin by converting 476 nm to m. This can be obtained as follow:
1 nm = 1×10¯⁹ m
Therefore,
476 nm = 476 nm × 1×10¯⁹ m / 1 nm
476 nm = 4.76×10¯⁷ m
Finally, we shall convert 4.76×10¯⁷ m to cm. This can be obtained as follow:
1 m = 100 cm
Therefore,
4.76×10¯⁷ m = 4.76×10¯⁷ m × 100 cm / 1 m
4.76×10¯⁷ m = 4.76×10¯⁵ cm
Thus,
476 nm = 4.76×10¯⁵ cm
H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.
