Explanation:
Given that,
The mass of the object, m = 5 kg
We need to find the maximum potential energy. When the height of the object is maximum it will have the maximum potential energy.
The attached figure shows that the maximum height is 25 m. The formula for the potential energy is given by :

So, when the height is 25 m, the object will have the highest potential energy.
It would be d.
Reason being said...
the electron configuration normally goes like this...
1s2 2s2 2p6 3s2 3p6 4s2....
until you hit the transition metals..remember those have a special rule..
even though you are in the 4 sublevels for the orbitals ... it goes down 1
Making it 3d..(1,2,3,4,5,6,7,8,9,10)
Going on...
at 5s2 then, 4d1, 4d2, 4d3, 4d4, etc..
at 6s2 then, 5d1, 6d2, 6d3, 6d4, etc..
Thus, D orbital is your answer.
The elements are Krypton and Xenon
Answer:
A) 1.3 × 10⁻⁵ mol/L
Explanation:
Step 1: Write the balanced equation for the solution of AgCl
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
Step 2: Make an ICE Chart
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
I 0 0
C +S +S
E S S
If we replace the solubility (S) in the Ksp expression, we get,
Ksp = [Ag⁺] [Cl⁻] = S × S = S²
S = √Ksp = √1.8 × 10⁻¹⁰ = 1.3 × 10⁻⁵ mol/L
Well, this is obviously an opinion question, so share your opinion. If you are happy that the Agricultural Revolution(s) paved way for the earth to sustain billions of people, then that's great. But, if you wish there were fewer people on the planet, then share that. Of course, both sides have their pros and cons. Just share your opinion. Good luck!
