In a combination redox reaction, two or more compounds, at least one of which is a(n) compound, form a(n) products. General Reaction: X YZ → XZ Y. In a decomposition redox reaction, a(n) compounds forms two or more atoms (or ions), at least one of which is a(n) ion. General Reaction: Z → X Y In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, of two exchange places; these reactions redox processes. General Reaction: AB CD → AD CB In solution, single-displacement reactions occur when a(n) of one displaces the of another. Since one of the is a(n) , all single-displacement reactions redox processes. General Reaction: X Y → Z

Answer 1

Answer:

Answer:

Here's what I get

Explanation:

In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, the cations of two compounds exchange places; these reactions are not redox processes.

General Reaction: AB + CD → AD + CB

In solution, single-displacement reactions occur when an atom of one element displaces the atom of another. Since one of the reactants is an element, all single-displacement reactions are redox processes.

General Reaction: X + YZ → XY + Z

Answer 2

Answer:

Answer :

In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, the cations of two reactants exchange places; these reactions are not redox processes.

In solution, single-displacement reactions occur when an atom of one element displaces the atom of another. Since one of the reactants is an element, all single-displacement reactions are redox processes.

Explanation :

Double-displacement reaction : It is defined as the reaction in which the cation of two reactants molecule exchange their places to give two different products.

The double-displacement reaction are not a redox reaction.

It is represented as :

$AB+CD\rightarrow AD+CB$

Where A and C are the cations and B and D are the anions.

Single-displacement reaction : It is a type of reaction in which the more reactive metal displaces the least reactive metal from its solution.

It is represented as :

$A+BC\rightarrow AC+B$

Where A is the most reactive metal and BC is the compound in which the B is the least reactive metal which is displaced by the most reactive metal A.

The single-displacement reaction are a redox reaction.

3.54 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = (mass)/(density) \n$

From the question

mass = 9.38 g

density = 2.65 g/cm³

The volume of the quartz is

$volume = (9.38)/(2.65) \n = 3.539622641...$

We have the final answer as

3.54 mL

as a result of the gold foil experiment it was concluded that an atom (1) contains protons, neutrons, and electrons(2)contains a small, dense nucleus(3)has positrons and orbitals (4)is a hard and invisible sphere

Answers

It showed that the atom contains a small dense nucleus. The reason why this can be concluded is that the experiment showed that alpha particles can for the most part pass right through the foil. This showed that the nucleus of the atom is very small and takes up a very small portion of the size of an atom since the nucleus is what would reflect the alpha particle. If atoms were not mostly empty space, the alpha particles would have been bounced back and the opposite of what was observed would have happened (all or at least the majority would be bounced back instead the majority getting through with only a small portion being reflected back).

I hope this helps. Let me know in the comments if anything is unclear.

Final answer:

The gold foil experiment, conducted by Ernest Rutherford, discovered the existence of a small, dense nucleus within an atom, making answer (2) the correct one.

Explanation:

The gold foil experiment was conducted by Ernest Rutherford and led to the discovery of a small, dense nucleus within the atom. This means that the correct answer to your question is (2) contains a small, dense nucleus. Prior to this experiment, the widely accepted model was the 'plum pudding' model, which had negatively charged electrons embedded within a positively charged sphere. The gold foil experiment upended this model as it was discovered that most alpha particles passed through the gold foil undeterred, but a small fraction was deflected at large angles, suggesting that a tiny but dense packet of positive charge — identified as the nucleus — existed in the center of the atom. This discovery led to the formation of the Rutherford atomic model.

Given the equation:C2H6 + Cl2 --> C2H5Cl + HCl
This reaction is best described as
(1) addition involving a saturated hydrocarbon
(2) addition involving an unsaturated hydrocarbon
(3) substitution involving a saturated hydrocarbon
(4) substitution involving an unsaturated hydrocarbon

Answers

This reaction is best described as substitution involving a saturated hydrocarbon. Therefore, the correct option is option C.

When one atom or group of atoms in a molecule is replaced by another atom or group of atoms, the chemical reaction is known as a substitution reaction. Usually, a reactant molecule and a reagent molecule, which supplies the replacing atom or group, engage in this reaction. Nucleophilic substitution and electrophilic substitution are the two primary categories of substitution processes. A nucleophile (a substance rich in electrons) can replace another atom or group in a molecule in nucleophilic substitution processes. A nucleophile combines with an electrophile (an electron-deficient species) in organic chemistry regularly to produce this kind of reaction, which results in the formation of a new molecule.

The reaction is a substitution reaction
involving a saturated hydrocarbon. You
have substitued a chlorine atom for one of the hydrogen atoms, and the hydrocarbon you start with (ethane) is fully saturated.
