Answer:
8 electrons
Explanation:
as the the 1st period (H and He), it can hold up to 2 electrons. in the 2nd period (Li, Be, B, C, N, O, F and Ne), it can hold up to 8 electrons. Itstops at 6 when it reached O. add the lelectrons that you have
2+6=8
8 electrons
If you mean m (subscript l) is (-2,-1,0,1,2)
its a 3d orbital so it can hold 2 electrons, however, like in an electron diagram a 3d orbital has 5 boxes can can hold 2 electrons that is how i got 10 total but if you mean just in box 2 then only 2 can share it.
Does that make sense?
Velocity is defined as displacement over time. Could you have possible meant viscosity? If so, viscosity is defined as the state of being thick, sticky, and semifluid in consistency, due to internal friction. And example of a substance with a high viscosity would be honey.
Answer:
The answer to your question is pH = 8.5
Explanation:
Data
pH = ?
[H₃O⁺] = 3.0 x 10⁻⁹ M
Formula
pH = -log [H₃O⁺]
-Substitution
pH = -log [3.0 x 10⁻⁹]
-Simplification
pH = -(-8.523)
-Result
pH = 8.523
-Conclusion
pH of a solution with a [H₃O⁺] of 3.0 x 10⁻⁹ is 8.5, then it is an alkaline solution.
The reaction rate of a chemical reaction is determined by the slow step in the reaction mechanism.
The rate ii given by the product of the species of the determining step, each raised to its coeeficient in the chemical reaction that represents this step.
So, given that the determining step is represented by A + 2B→C, the reaction rate is r = k[A]*[B]^2.
This mechanism is verified becasue the total order is the summ of the coefficientes : 1 + 2 = 3 and the exponent 2 makes B is a bigger rate determinant than A.
So, the answer is the option b. k[A][B]^2.
