Answer:

The answer to your question is: hydrogen bonding

Explanation:

Hydrogen bonding is a kind of interaction dipole-dipole, that means that 2 molecules attract each other because the have partial charges.

In the picture we can see 4 molecules of water, red circles are oxygens and white circles are hydrogens. In this bonding, Oxygen due to its size, and atomic number is more electronegative than hydrogen, then in water molecule is formed a partial negative charge in oxygen and a partial positive charge in hydrogen.

Finally, because of this partial charge, one oxygen can bond to one hydrogen of another molecule.

Chemist preformed Reaction of solid magnesium burning and found that the mass of the magnesium oxide what is greater than the ma
tankabanditka [31]

Answer:

The magnesium reacted with the oxygen in the air.

Explanation:

For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.  

The reaction was

            magnesium + oxygen ⟶ magnesium oxide

Mass:           3 g                                          5 g

Mass of oxygen = 5 g – 3 g = 2 g

The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.

Why does thermal energy decreases when potassium is dissolved in water​
Levart [38]

Answer:

The process of dissolving can be endothermic (temperature goes down) or exothermic (temperature goes up).

When water dissolves a substance, the water molecules attract and “bond” to the particles (molecules or ions) of the substance causing the particles to separate from each other.

The “bond” that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water’s polarity.

It takes energy to break the bonds between the molecules or ions of the solute.

Energy is released when water molecules bond to the solute molecules or ions.

If it takes more energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes down (endothermic).

If it takes less energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes up (exothermic).

You are given two closed containers. Each containing a liquid solvent. Ammonia and table salt will dissolve in container A. Hexa
snow_tiger [21]
Ammonia and table salt dissolves in polar solvents, so A is water,
CO2 and hexane are non-polar substances, so they are going to be dissolved in non-polar solvent, so I think it is going to be carbon tetrachloride

Answer is <span>A) A - water; B - carbon tetrachloride

Table salt does not dissolve in oil and CCl4, and Br2 is too active and it is going to react with NH3.</span>

Which particle diagram represents a mixture of three substances
Anni [7]

Following the key in the diagram (see the attached image), the only particle diagram that represents a mixture of three substances is diagram 2.

To simplify it, let us replace the key in the diagram as follows;

  1. atom of one element = A
  2. atom of different element = B

Diagram 1 consists of only AA and AB

Diagram 2 consists of AA, BB, and AB.

Diagram 3 consists of AA and ABA

Diagram 4 consists of AA and BAB

Thus, only diagram 2 has a mixture of 3 substances.
