Answer:If we have [H+][OH-]= Kw = 1.0 x 10^-14

Then [H+]= Kw/ [OH-]= 1.0x 10^-14/ 1 x 10^-11 =1 x 10^-3 mol/L

And here is the solution - as you can see it is an acidic one :

pH = - log [H+]= - log 1 x 10^-3 = 3 < 7

Answer:

[H+] = 0.01mol/L

Explanation:

p[OH] = -log[OH-]

[OH-] = 1*10^-12

pOH = -Log[1*10^-12]

pOH = 12.

But pH + pOH = 14

pH = 14 - pOH

pH = 14 - 12

pH = 2

pH = -Log[H+]

2 = -Log[H+]

Take the anti log of both sides

10⁻² = [H+]

[H+] = 0.01

The hydrogen ion concentration is 0.01mol/L

Why do many metal ions produce acidic solutions when dissolved in water?
lakkis [162]
<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>

The combustion of 1 mole of CO according to the reaction CO(g) + ½O2(g) → CO2(g) + 67.6 kcal gives off how much heat?
Tomtit [17]
When the enthalpy value is given, we can calculate how much heat is use or produces in a given equation. 

67.6 kCal ---> 67.6 kCal= 1 mol of reaction
1 mol of reaction=  1 mol of CO (based on the coefficient)

so 1 mole of CO gives us 67.6 kCal of heat.

calculation:

1 mol CO\frac{67.5 kcal}{1 mol CO} = 67.5 kcal

Calculate the energy of a photon of 765 nm wavelength light in J.
weqwewe [10]

Answer:

2.6×10^-19 J/photon

Explanation:

E  of photon  =  h  ×  ν

where h= 6.63 × 10^-34 j.s

v= C ÷ λ

E = ( h × c) ÷ λ

E = (6.63 × 10^-34 × 3.00 ×10^8 )  ÷ ( 765 × 10^-9)

E = 2.6×10^-19 J/photon
