Answer:

The concentration of hydronium ions in the solution is 1.0\times 10^{-2}M.

Explanation:

Concentration of hydroxide ions concentration = [OH^-]=1.0\times 10^{-12} M

The pOH if the solution is given by :

pOH=-\log[OH^-]

pOH=-\log[1.0\times 10^{-12} M}]

pOH = 12

The relation between pH and OH is given by : pH + pOH = 14

pH = 14 - pOH

pH =14 - 12 = 2

The pH of the solution isgiven by :

pH=-\log[H_3O^+]

2=-\log[H_3O^+]

[H_3O^+]=1.0\times 10^{-2} M

The concentration of hydronium ions in the solution is 1.0\times 10^{-2}M.

How many liters of fluorine gas, at standard temperature and pressure, will react with 23.5 grams of potassium metal? Show all o
Sladkaya [172]

Potassium 23.5g/39.0983g/mol = 0.601mol

The Ratio of reactants is 2 to 1 so (0.601mol)/2 = 0.3005mol

Therefore 0.3005mol of F2 is needed to find liters use

formula V = nRT/P (V)Volume = 22.41L

(T)Temperature = 273K or 0.0 Celsius

(P)Pressure = 1.0atm

<span>(R)value is always .08206 with atm n = 0.3005moles (273)(.08206)(0.3005)/1 = V V = 6.7319 Liters</span>

1. Find its coordination figure/coordination number of central atom (CF)

Ev = Vallence electron of central atom

Σe = electrons donated from substituents

Terminal O gives 0 electrons, hence Σe = 3 x 0

charge = charge of the compound

2. Find EP (electron pairs) and LP (lone pairs)

LP = CF - EP

3. Draw the skeleton with octet substituents (top right figure)
