I will make you brainliest! Very Easy question!!!!
Kitty [74]

Answer:

Synthetic Materials are man-made; natural materials are only warmer than synthetic materials, if the natural material is obtained from an animal. Wool is warmer than any synthetic material available, but <em>polyester</em> (a synthetic material) can be warmer than cotton (a natural plant-based material).

the solubility product of lead fluoride is 3.6 x 10–8. what is its solubility in 0.10M NaF solution, in grams per liter
BartSMP [9]

Answer:

8.8 × 10⁻³ g/L

Explanation:

NaF is a strong electrolyte that ionizes according to the following reaction.

NaF(aq) → Na⁺(aq) + F⁻(aq)

Then, the concentration of F⁻ will also be 0.10 M.

In order to find the solubility of PbF₂ (S), we will use an ICE Chart.

        PbF₂(s) ⇄ Pb²⁺(aq) + 2 F⁻(aq)

I                           0                0.10

C                         +S               +2S

E                          S              0.10 + 2S

The solubility product (Kps) is:

Kps = 3.6 × 10⁻⁸ = [Pb²⁺].[F⁻]² = S . (0.10 + 2S)²

In the term 0.10 + 2S, 2S is negligible in comparison with 0.10 and we can omit it to simplify calculations.

Kps = 3.6 × 10⁻⁸ = S . (0.10)²

S = 3.6 × 10⁻⁵ M

The molar mass of PbF₂ is 245.20 g/mol. The solubility of PbF₂ in g/L is:

3.6 × 10⁻⁵ mol/L × 245.20 g/mol = 8.8 × 10⁻³ g/L

If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?
olya-2409 [2.1K]

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

m=\dfrac{h'}{h}

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm

So, the size off the object is same as that of the size of the image i.e. 10 cm.
