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.

If the concentration of brown sand is 2.0 ppm, how many grains of brown sand are in the bucket?

AysviL [449]

I believe the complete given is that the bucket of sand contains 9.5 billion grains of sand. That is:

bucket = 9,500,000,000 grains

and the concentration of brown sand is 2 ppm:

concentration brown sand = 2 / 1,000,000

Therefore:

brown sand = 9,500,000,000 * (2 / 1,000,000)

brown sand = 19,000 grains

How is the relative abundance calculated?

OverLord2011 [107]

Atomic weights are weighted averages calculated by multiplying the relative abundance of each isotope by its atomic mass and then summing up all the products.

One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin c, c6h8o6). given that one cup

kodGreya [7K]

The question is incomplete. Complete question is read as:
'One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin C, C6H8O6). Given that one cup = 218.0 mL calculate the molarity of vitamin C in organic juice.'
..........................................................................................................................
Answer:
Given: weight of solute (ascorbic acid) = 115 mg = 0.115 g
Volume of solution = 218.0 mL = 0.218 L
Molecular weight of ascorbic acid = 176.12 g/mol.

Now, Molarity = $\frac{\text{weight of solute(g)}}{\text{Molecular weight X Vol. of solution(l)}}$
= $\frac{\text{0.115}}{\text{176.12 X 0.218}}$
 = 0.002995 mol/dm3

Answer: Molarity of solution = 0.002995 mol/dm3
