The disturbance of a supersaturated solution will cause precipitation. A supersaturated solution is a solution that contains more solute than the solvent can dissolve. When this type of solution is disturbed like when it is moved, the formation of a solid is observed immediately.

how many H+ ions are in a solution with a pH of 2 and how many H+ ions are in a solution with a pH of 6?
LiRa [457]

Answer:

i) pH = 2

pH = -log(H+)

:- (H+) = 10^(-2)

:- (H+) = 0.01 M

ii) pH = 6

pH = -log(H+)

:- (H+) = 10^(-6)

:- (H+) = 0.000001 M

Explanation:

By definition: pH = -log(H+).

Given your pH, solve for the H+ using the the following log rule:

if a = (+/-) log (b) then

b = 10^((+/-) a).

Also remember unit of concentration is molar (M)

Which of the following has more atoms?
aniked [119]

Answer:

They all have the same number of atoms

Explanation:

Which of the following has more atoms?

One mole of zinc

One mole of gold

One mole of silver

One mole of magnesium contians  

O They all have the same number of atomst

a mole of anything contains Avogadros number of 6.022X10^23  things

which has the greatest number of thing? a dozen eggs, a dozen cookies, a dozen pizzas?

a dozen is a number means 12

a mole is a number that that means 6.022 X 10^23 you calculate the molar mass from the chemical formula, but every j mole contains 6.022X10^23

particles.

just like every dozen contains 12

so

They all have the same number of atoms

The density of a rock that was a mass of 454 grams and a volume of 100 cm3
puteri [66]

Answer:

The answer is

<h2>4.54 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of rock = 454 g

volume = 100 cm³

The density of the rock is

density =  \frac{454}{100}  =  \frac{227}{50}  \\

We have the final answer as

<h3>4.54 g/cm³</h3>

Hope this helps you
