Explanation:
ABC looks like the metamorphic rocks are more usable than other rocks
Answer:
We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.
Explanation:
We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other
Definitions needed:
pH = -log[H^+]
pOH = -log[OH^-]
pH + pOH = 14
[H^+]*[OH^-] = 10^-14
(a) [H+] = 3.0 10-13 M
[OH ‾ ] = _____ M
Acidic, Basic, or Neutral?
[H^+]*[OH^-] = 10^-14
[OH^-] = (10^-14)/[H^+]
[OH^-] = (10^-14)/(3.0 10-13 M) = 0.033 M
That's a high concentration of [OH^-], so the solution is basic
(b) [OH ‾ ] = 3.0 10-7 M
[H+] = ______M
Acidic, Basic, or Neutral?
[H^+]*[OH^-] = 10^-14
[H^+]* = (10^-14)/[OH^-]
[H^+]* = (10^-14)/(3.0 10-7 M) = 3.33 x 10^-8
That would be a slightly basic solution (pH just higher than 7).
Mass = moles x Mr
So in this case the moles =1
And the Mr equals =11
So you would do - 11x1= 11grams
Helium will have the highest kinetic energy.
