H = 1.008
S = 32.066
F = 18.998
O = 15.999
(1.008 x 2) + (32.066 x 2) = 66.148 g/mol
(1.008) + (18.998) + (15.999 x 2) = 52.004
Let me know if you need any further help!
Q1)
We have been given the OH⁻ concentration, therefore we first need to find the pOH value and then the pH value.
pOH = -log [OH⁻]
pOH = -log (0.225 M)
pOH = 0.65
pH + pOH = 14
pH = 14 - 0.65 = 13.35
Q2)
pOH = -log[OH⁻]
pOH = -log (0.0015 M)
pOH = 2.82
pH + pOH = 14
pH = 14 - 2.82
pH = 11.18
Answer:
The correct answer is option C.Water molecules move throughout the solute
Explanation:
The basic standard for solute disintegration in a specific dissolvable is "like breaks up like". On account of water, a solute will disintegrate if it is polar. This is on the grounds that water is a polar dis-solvable. A polar substance is one which has particles that have a net charge on them. This net charge produces powers of fascination.
At the point when a polar solute is added to water, the water atoms are pulled in to the solute particles and they join to them. In the wake of appending to the water atoms, the solute particles are scattered all through the water. Accordingly, the appropriate response is particles or particles of a solute spread all through the water atoms.
Answer:
[Ne] 3s² 3p²
Explanation:
Silicon atoms have 14 electrons. The ground state electron configuration of ground state gaseous neutral silicon is 1s²2s²2p⁶3s²3p².
Using noble gas shorthand, the electronic configuration is reduced to;
[Ne] 3s² 3p². Ne s the nearest noble gas to silicon, Ne contains 8 electrons, this means there's still 4 more electrons to fill. The s orrbital can only hold 2, hence the reaing two is transferred to the p orbital.
