what would be the best way to determine the amount of AgNO3 in the dissolved solution? Justify your answer

Answers

Answer 1

The best way to determine the concentration of AgNO3 dissolved in solution is by precipitation using a chloride.

Precipitation is one of the oldest and handy methods of chemical analysis. It involves the addition of a reagent which is known to form a precipitate with the test solution.

The precipitate is now recovered from solution, dried and weighed. Stoichiometric calculations show the amount of the test substance dissolved in the test solution.

In this case, NaCl can be used to carry out a precipitation as follows;

AgNO3(aq) + NaCl(aq) -------> AgCl(s) + NaNO3(aq)

The AgCl precipitate is recovered dried and weighed and then the amount of AgNO3 in the dissolved solution is determined.

Answers

Answer:

Explanation:

EDMENTUM

The Lewis structure for ozone contains a central oxygen atom that has a double bond to one oxygen atom and a single bond with the other oxygen atom. The resonance structure of the ozone is shown in the attached figure below.

What is the lewis structure of the ozone molecule?

The oxygen molecule has a valency of -2. It can form two-sigma bonds or covalent bonds with the other atoms. Oxygen contains three lone pairs to form π bonds with other atoms. Ozone contains all three oxygen atoms and is a dihedral molecule with sp² hybridization.

Lewis structure is generally based on the octet rule which states that there should be eight electrons in the valence shell or orbit of an atom for a stable molecule.

The lone pair on the central oxygen atom repels the electrons in the two side bonds and adopt a bent molecular geometry. The expected geometry is the trigonal planar with a bond angle is 120°.

In an ozone molecule, six valence electrons for each molecule of Oxygen so the total number of valence electrons is 6 × 3 = 18. As both Oxygen atoms on the sides have the same electronegativity, therefore, the double bond keeps on shifting from both causing resonances.

Answers

The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).

The pH of a salt solution depends on the nature of the acid and base that forms the salt.

Salt of a weak acid and a strong base yields a basic solutionSalt of a strong acid and a weak base yields an acidic solutionSalt of a strong acid and a strong base yields a neutral solution.

Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.

The size of the atoms (atomic radius) would increase down the group from neon to argon to krypton.

What is atomic radius?

Atomic radius can be defined as a measure of the size (distance) of the atom of a chemical element, typically from the nucleus to its valence electrons.

The trends of atomic radius.

Generally, the atomic radius of a chemical element decreases across the periodic table, from alkali metals (group 1 elements) to noble gases (group 8 elements). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).

Answers

The history of the atom passed through a certain sequence until our recent interpretation of atomic theory.

The correct sequence of atomic theory is;

The atom at electrons stuck in an overall  positive atomThe atom has a small dense positive  nucleus. Electrons exist in perfect orbits based on  energy levels.Electrons exist in orbitals, or the most  probable location

The beginning of the atomic theory saw the discovery of J.J Thompson which led to the plum - pudding model in which the atom was described as a sphere in which electrons are stuck in an overall  positive atom.

This was followed by Rutherford's planetary model in which he concluded that the atom has a small dense positive  nucleus. This was followed by the model of Bohr in which the electrons exist in perfect orbits based on  energy levels.

Lastly, the contemporary model of the atom is called the wave - mechanical model in which electrons exist in orbitals, or the most  probable location.

Determine the mass percentage of carbon, C, hydrogen, H, and oxygen, O, in C6H8O7. Refer to the periodic table for the atomic mass of each element.

Answers

Answer:

C=37.5% H=4.2% O=58.3%

Explanation:

molar mass of element / molar weight of compound X 100% (for each element)

C mass = 12 x 6 = 72

H mass = 1 x 8 = 8

O mass =16x 7 = 112

Molar weight of compound = 192

72/192(100%)= 37.5% C

8/192(100%) = 4.2 % H

112/192 (100%) = 58.3% O

The mass percentage of carbon, hydrogen, H, and oxygen, O, in C₆H₈O₇ is C = 37.5% H = 4.2% O = 58.3%.

What is the mass percentage?

The concentration of an element in a compound or component in a combination is calculated by the mass percentage.

The collective of a component is divided by the entire mass of the mixture to obtain the mass percentage, which is then multiplied by 100%.

Given, finding the mass percentage of carbon, hydrogen, H, and oxygen, O, in C₆H₈O₇

the molar mass of element / molar weight of compound X 100% (for each element

First, calculate the molar mass of the elements given in the compound.

C mass = 12 x 6 = 72

H mass = 1 x 8 = 8

O mass =16x 7 = 112

Molar weight of compound = 192

72/192(100%)= 37.5% C

8/192(100%) = 4.2 % H

112/192 (100%) = 58.3% O

Thus, the mass percentage is C = 37.5% H = 4.2% O = 58.3%.
