Answer:

The answer to your question is pH = 3

Explanation:

Data

[H⁺] = 1 x 10⁻³

pH = ?

pH is a measure of the hydrogen concentration. It measures the acidity or alkalinity. The range of pH goes from 0 to 14. The pH for an acid is from 0 to 6.9, for a neutral solution is 7.0 and for an alkali is from 7.1 to 14.

Formula

pH = -log [H⁺]

-Substitution

pH = -log [1 x 10⁻³]

-Simplification

pH = - (-3)

-Result

pH = 3

I need help...

Aneli [31]

Answer:

1. Density of the rectangular prism is 20 g/cm3

2. A material's ability to dissolve : Soubility

3. Intensive property : A physical property that is independent of sample size.

Explanation:

Volume of Prism is calculated by :

$volume = L\times W\times H$

Length = 3 cm

Width = 2 cm

Height = 1 cm

$volume = 3\times 2\times 1$

V = 6 cm3

mass = 120 g

$Density = \frac{mass}{Volume}$

$Density = \frac{120}{6}$

Density = 20 g/cm3

Solubility :

It is the chemical property of the substance.

It shows the ability of the solute to dissolve in the solvent at a given temperature.

Intensive Properties:

These are bulk properties(Do not depend upon the amount of matter present)
They are independent of sample size.
Example : boiling point,melting point,temperature,refractive index

Which metal ions can be precipitated out of solution as chlorides?a. Ag+, Hg2+, Co2+b. Cu2+, Cd2+, Bi3+ c. Ag+, Hg22+, Pb2+ d. N

Fudgin [204]

Answer:

Explanation:

In the qualitative analysis of metal salts , we see that in group I , metal chlorides are precipitated out . It is so because their metal chlorides are insoluble in water .

In this group following metal ions are present

Ag+,

Hg₂²⁺

Pb²⁺
