The concentration of 1130+ in a solution is found to be 1.75 X 10-8 M 250C. Find [OH].
const2013 [10]

Answer:

[OH] = 6.31 * 10^-7 M

Explanation:

Mathematically;

pH + pOH = 14

Mathematically;

pH = -log [H3O+]

also;

pOH = -log [OH]

From the question; [H3O+] = 1.75 * 10^-8 M

pH = -log [1.75 * 10^-8]

pH = 7.76

since pH is normally given to 1 decimal place

we can say pH = 7.8

Now;

pH + pOH = 14

pOH = 14-7.8

pOH = 6.2

now pOH = -log [OH]

[OH] = -antilog 6.2

[OH] = 6.31 * 10^-7 M

Calculate the number of atoms in 4.8 dm^3 of neon gas at rtp
WINSTONCH [101]

No of atoms in 4.8 dm³ of neon gas is determined in the following way.

Explanation:

We have given

Neon Gas=4.8dm³

At STP

1 mole of an ideal gas occupies 22.4 L(dm³) of volume.

which means that  number of molecules occupy 22.4 L of volume.

So

4.8 dm³x 1 mole/22.4 dm³ = 0.214 moles Neon

0.214 moles x 6.02x10²³ atoms/mole = 1.29x10²³ atoms of Neon

No of Atoms in 4.8dm3 neon gas =1.29x10²³ atoms of Neon

Use molecular orbital theory to determine whether f22+ is paramagnetic or diamagnetic.
Alexxandr [17]

We have to know whether F₂²⁺ is paramagnetic or diamagnetic.

F₂²⁺ is paramagnetic.

If number of unpaired electron in any species is equal to zero, the species is diamagnetic and the species contains unpaired electrons, then the species is paramagnetic.

The magnetic property can be explained using molecular orbital theory.

Total number of electron present in   F₂²⁺ is equal to 16 (i.e, 9+9-2). From the molecular orbital electronic configuration, number of electrons present in pi orbitals present is equal to 2.

So,  F₂²⁺ is paramagnetic.
