The skateboard's acceleration would decrease.
The larger the mass of an object, the more force is required to move it.
Answer:
The answer to your question is: pOH = 5.7
Explanation:
pOH is a measure of the concentration of OH ions.
Data
pOH = ?
Molarity = 2.1 x 10 ⁻⁶ M
Formula
pOH = -log [OH]
Substitution
pOH = -log[2.1 x 10⁻⁶]
pOH = 5.7
and pH = 14 - pOH
pH = 14 - 5.7
pH = 8.3
Are you talking about stp? That would be 1 atm to 760 mm hg to 760 torr
Temperature would be 273K
Volume would be 22.4
Moles of any gas would be 1
(a)
Write balanced half-reactions for the process:
Oxidation: Se^2- (aq) → Se
(s) + 2e-
Reduction: 2So3^2- (aq) + 3H2O (l) + 4e- →
S2O3^2- + 6OH- (aq)
(b)
If E sulfite is 0.57 V, calculate E selenium:
E anode = E cathode – E cell
= -0.57 – 0.35
=
-.092
