Which of the following is true about the composition of ionic compounds?

Chemistry

NISA [10]3 years ago

Answer:

a. They are composed of anions and cations

Explanation:

Ionic compounds are molecules in which the constituent atoms are connected by ionic bonds.

Ionic bonds are formed by the transfer of electrons from one atom to the other. The atom that loses electrons becomes positively charged and referred to as a cation. Whereas, the atom that gains electrons becomes negatively charged i.e. an anion.

For example, common salt (sodium chloride) NaCl is an ionic compound which is essentially Na⁺Cl⁻.

Thus, ionic compounds are composed of anions and cations.

Calculate the molar mass of iron(III) sulfide. Round your answer to the nearest 0.1 and include units to receive credit.
Igoryamba

Answer:

207.89g

Explanation:

The formula of the compound is:

        Fe₂S₃  

Find the molar mass of the compound;

  Atomic mass of Fe  = 55.845g/mol

                              S  = 32.065g/mol

Now;

  Molar mass of  Fe₂S₃   = 2 (55.845) + 3 (32.065)

                                         = 207.89g

LuckyWell [14K]

Answer:

B

Explanation:

Option B is the correct answer. When you add 7 in front of the O2 in the left side, and then you add 4 and 6 in front of NO2 and H2O respectively, the number of oxygen atoms is the same in both sides.

Pachacha [2.7K]
<h2><u>Full Question:</u></h2>

In hemoglobin, a single amino acid change at position 6 from Glu to Val has major consequences on hemoglobin structure that makes the molecule defective leading to sickle cell anemia. Predict whether the following hypothetical change would or would not have a major effect at position 6. Briefly explain (1-2 sentences). Glu to Leu Hint: Look at the structures of the R groups and consider their chemical properties

<h2><u>Answer:</u></h2>

The structure of the haemoglobin, hence the RBC won't be same as normal.

<h3><u>Explanation:</u></h3>

Both the leucine and glutamic acid are alpha amino acids which have an alpha carboxylic acid group and an alpha amino group. The variable in case of glutamic acid is propyl acid while the variable in case of leucine is isobutyl.

The glutamic acid is the normal amino acid of the 6th position of Beta chain of hemoglobin. Its an acid group, so can form bonds with another base inside the haemoglobin, or can form other hydrogen bonds. But the isobutyl group is an alkyl group. So it doesn't have that much effect in the recovering the structure, and sickle cell anemia prevails.

Answer:

9 atoms

Explanation:

Explanation: In 1 formula unit of Al(NO3)3 , there are (clearly!) 9 atoms of oxygen, 3 nitrogen atoms, and 1 aluminum atom. I have gone on before that the mole ( NA , Avogadro's number) is simply a much larger number, i.e. NA = 6.022×1023 .
