In an oxidation-reduction reaction, the total number of electrons lost is(1) equal to the total number of electrons gained
(2) equal to the total number of protons gained
(3) less than the total number of electrons gained
(4) less than the total number of protons gained

Answers

Answer 1

Answer:

Answer is: (1) equal to the total number of electrons gained.

In oxido-reduction reaction, at least one element lose and one element gain electrons.

Oxidation reaction is increasing of oxidation number of atom, because element lost electrons in chemical reaction.

Reduction is lowering oxidation number because atom gain electrons.

For example, in oxidation-reduction reaction: 2H₂ + O₂ → 2H₂O; hydrogen is oxidized (change oxidation number from 0 to +1) and oxygen i s reduced (change oxidation number from 0 to -2).

Hydrogen lost .four electrons anf oxygen gain four electrons

Answer 2

Answer: In redox reactions, there is no net loss or gain of electrons, so the answer is (1) equal to the total number of electrons gained

What is the structure of beeswax that contains 16 carbon of carboxylic acid and 30 carbon of alcohol?

Answers

Answer:

Tricontanyl palmitate: CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃

Explanation:

Beeswax is a tough natural wax which is produced by the worker honey bees. The beeswax is an ester of the long chain fatty acids and alcohols. One of the major components of beeswax is tricontanyl palmitate.

Tricontanyl palmitate is a wax ester that is composed of 16-carbon fatty acid and a 30-carbon alcohol, joined by an ester linkage.

The molecular structure of tricontanyl palmitate is:

CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃

Which statement explains why the bonds between nonmetals tend to be covalent? The bonds are found to be nondirectional. They have large differences in electronegativity. They have small differences in electronegativity. They have ions that produce an electrostatic pull.

Answers

Correct Answer: They have small differences in electronegativity (statement 3)
Reason:
The nature of chemical bond between atoms is primarily driven by the electronegativity difference between constituent atoms. If electronegativity difference between constituent atoms is significantly higher, ionic bond formation is preferred. On other hand, low difference in electronegativity values, favours formation of covalent bond.

The distance between stars is typically measured in

Answers

The distance between stars is typically measured in light years, or the amount of distance traveled by light in one year. This is because stars are extremely far apart, and measuring the distance with a smaller unit of measurement would result in ridiculously large numbers that would be difficult to work with.

Final answer:

The typical measure for the distance between stars is the light-year. Light-year and parsec are units used to quantify the enormous distances in the universe.

Explanation:

The distance between stars is typically measured in light-years. This term, 'light-year', refers to the distance that light can travel in one year, which is approximately 9.461 trillion kilometers or 5.879 trillion miles. Another less commonly used unit is the parsec, which is equivalent to about 3.26 light years. Such large units are necessary due to the vast distances between stars in the universe.

So, The distance between stars is typically measured in light-years.

Given the reaction: HC2H3O2(aq) + H2O ↔ H3O+(aq) + C2H3O2-(aq) When the reaction reaches a state of equilibrium, the concentrations of the reactants 1. are less than the concentrations of the products 2. are equal to the concentrations of the products 3. begin decreasing 4. become constant

Answers

The correct answer for the question that is being presented above is this one: "2. are equal to the concentrations of the products." Given the reaction: HC2H3O2(aq) + H2O ↔ H3O+(aq) + C2H3O2-(aq) When the reaction reaches a state of equilibrium, the concentration of product is equal yo the reactant.

Answer:

Explanation:

The concentration of a solid or a liquid is essentially constant at equilibrium, because the forward and reverse reaction rates are equal.

Balance the following oxidation-reduction reaction: Fe(s)+Na+(aq)→Fe2+(aq)+Na(s) Express the coefficients as integers separated by commas (e.g., 4,1,3,2, where 1 indicates the absence of a coefficient).

Answers

Answer:

The answer to your question is: 1, 2, 1, 2

Explanation:

1 Fe(s) + 2 Na⁺(aq) → 1 Fe²⁺(aq) + 2 Na(s)

Fe⁰ - 2e⁻ ⇒ Fe⁺² Oxidases

Na⁺ + 1 e⁻ ⇒ Na⁰ Reduces

1 x ( 1 Fe⁰ ⇒ 1 Fe⁺²) Interchange number of

2 x ( 2Na⁺ ⇒ 2 Na⁰ ) electrons

Final answer:

To balance the oxidation-reduction reaction Fe(s) + Na+(aq) → Fe2+(aq) + Na(s), follow these steps: balance atoms other than hydrogen and oxygen, balance hydrogen atoms, balance oxygen atoms, verify charges

Explanation:

To balance the oxidation-reduction reaction Fe(s) + Na+(aq) → Fe2+(aq) + Na(s), we need to balance the number of atoms for each element and the total charge on both sides of the reaction. Here's the step-by-step process:

First, balance the atoms other than hydrogen and oxygen. There is only one atom of Fe on each side, so this is already balanced.
Next, balance the hydrogen atoms. We have no hydrogen on the left side and one hydrogen on the right side, so we need to add a coefficient of 2 in front of Na(s): 2Na(s).
Now, balance the oxygen atoms. We have no oxygen on the left side and one oxygen in Fe2+(aq), so we need to add a coefficient of 2 in front of Fe2+(aq): 2Fe2+(aq).
Finally, verify that the charges are balanced. The charge on the left side is 1+ (from Na+) and the charge on the right side is 0 (from Na). To balance the charges, we need to add a coefficient of 2 in front of Na+: 2Na+(aq).

So, the balanced oxidation-reduction reaction is: Fe(s) + 2Na+(aq) → 2Fe2+(aq) + Na(s).
