Answer:

protons: 36

neutrons:48

electrons:36

Explanation:

the number of protons in an element is = to the atomic # (36)

the number of neutrons is the atomic mass - atomic # (84-36=48)

In a neutral charged element the # of protons = # of electrons

An ionic solid is placed in a beaker of water. Which of the following occurs when there is a strong attraction between the solute and the solvent?A. The solute melts.
B. The solute dissolves.
C. The solute remains intact.
D. The solute reacts to form a precipitate.

Answers

Answer: Option (B) is the correct answer.

Explanation:

An ionic solid is a substance which has ionic bonds, that is, formed by the transfer of electrons.

Ionic bonds have strong force of attraction because ionic solids have opposite charges which strongly attract each other.

When we dissolve ionic solid in a beaker of water, it completely dissociate into its ions because polar molecules or solutes dissolve in polar solvents.

For example, when NaCl is dissociated into ions then the reaction is as follows.

$NaCl \rightarrow Na^(+) + Cl^(-)$

Thus, we can conclude that when an ionic solid is placed in a beaker of water then the solute dissolves in it.

The answer is B. the solute dissolves. The ionic solid has attraction between ions and when there is strong attraction between solute and solvent, the ion will separate and dissolve in water.

C 20:80 because the equation would be (10×.2)+(11×.8)

At STP, which of these substances is most soluble in H2O?(1) CCl4 (3) HCl
(2) CO2 (4) N2

Answers

The correct answer is option 3. Hydrochloric acid is the most soluble in water at standard temperature and pressure because it is has a polar covalent bond which makes it a polar molecule. Water is also a polar substance therefore hydrochloric acid will really be soluble in water.

Answer: Option (3) is the correct answer.

Explanation:

It is known that like dissolves like that is, a polar solvent will dissolve only polar compounds. Whereas a non-polar solvent will dissolve only non-polar compound.

Substances whose atoms have large difference in electronegativities are polar in nature. Water is a polar solvent and it is able to dissolve polar molecules.

For example, HCl is a polar or ionic compound so it is soluble in water.

On the other hand, $CCl_(4)$ , $CO_(2)$ , and $N_(2)$ are all non-polar as bond between them is formed due to sharing of electrons.

Hence, we can conclude that at STP, HCl is the substance that is most soluble in $H_(2)O$ .
