Why a mixture of magnesium hydroxide and water is known as milk of magnesia

Chemistry
1 answer:
gregori [183]2 years ago
3 0

because of its milk-like appearance. ... Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, magnesium hydroxide is considered a strong electrolyte. Its low solubility makes it a weak base.

Misha Larkins [42]

Answer:

Balancing chemical equation means making a number of atoms or molecules equal on both sides. In other words, this means that the number of atoms and molecules of each reacting element needs to be the same as the number of atoms and molecules of those elements in the product.

Our reaction is:

AlBr3 + K2SO4 -> KBr + Al2(SO4)3

and we need to balance it.

Since there are 3 molecules of SO4 in the product we need to put 3 before the reactant K2SO4. There are also 2 atoms of Al in the product, so we need to put 2 in front AlBr3. Now we have 6 atoms of K and Br on the left side, so we need to put 6 in front of KBr in the product.

So, our balanced equation will look like this:

2AlBr3 + 3K2SO4 -> 6KBr + Al2(SO4)3

Based on ecological studies, the definitions below applies to the given terms:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

Predidt the direction and the relative value of the dipole moment of the following bond: C-Cl
WINSTONCH [101]

Answer:

D. C → Cl electronegativity difference > 0.5

Explanation:

The electro negativity of an atom in a compound refers to its ability to attract the electrons of a bond towards itself.

On the Pauling's scale, carbon has an electro negativity value of 2.55 while that of chlorine is 3.16. The difference in electro negativity between the both atoms is about 0.61.

The dipole is aslways directed towards the more electronegative atom. Hence the direction is ; C → Cl
