Are These Synthesis Decomposition Single Replacement Or Double Replacement?

Answers

Answer 1

Answer:

1. Synthesis

2. Decomposition

3. Single replacement

4. Synthesis

5. Decomposition

6. Synthesis

Explanation:

Kind of a hard picture to look at but let me define each chemical reaction:

Synthesis:

a + b ---> ab   In synthesis elements/compounds come together to form new                compounds

Decomposition:

ab ---> a + b   In decomposition a compound breaks down to form 2 elements/compounds

Single replacement:

a + bc ---> b + ac   In a single replacement one element/compound takes the place of another element/compound.

Double replacement

ab + cd ---> ad + bc In a double replacement 2 compounds exchange different elements/compounds.

Now, let's go through the assignment

1. P + O2 --> P4O10  This is a synthesis reaction because the two elements (P and O) came together to form one compound.

2. HgO ---> Hg + O2  This is a decomposition reaction because HgO broke into separate elements Hg and O.

3. Cl2 + NaBr ---> NaCl + Br2  This is a single replacement reaction because chlorine (Cl) replaced the spot of bromine (Br) to bond with sodium (Na).

4.  Mg + O2 ---> MgO  This is a synthesis reaction because two elements (Mg and O) came together to form one compound.

5. Al2O3 ---> Al + O2  This is a decomposition reactions because Al2O3 broke into separate elements Al and O.

6. H2 + N2 ---> NH3  This is a synthesis reaction because two elements (H and N) came together to form one compound.

I hope this helps!!

According to the collision theory, which is required for a high number of effective collisions? a very low amount of force from colliding molecules a very low amount of kinetic energy from colliding molecules molecular collisions that have very specific orientations molecular collisions with energy to overcome activation energy

Answers

Answer:

the answer is D

Explanation:

i answered c and got it wrong on edg... i hope this helps :)

According to the collision theory, molecular collisions that have very specific orientations are required for a high number of effective collisions.

What is collision theory?

Collision theory is used to predict the rates of chemical reactions, particularly for gases.

Based on the collision theory, a high frequency of effective collision is dependent on the molecular collisions that have very specific orientations.

The collision theory suggests that for reactions to occur, there must collision between reacting particles.

The number of collision is dependent on the number of collision per unit time as well as fractions of effective collision.

To attain effective collision, colliding particles must be properly oriented to give the desired product.

Hence, option C is correct.

Suppose you wish to determine the order of the reaction. You initially measure a rate, r0, given some arbitrary concentration of reactants. You then proceed to double the amount of A in the reaction (keeping B the same) and find that the rate is now 2r0. In a reciprocal experiment, you double the amount of B (A same as initial) in the reaction and measure a rate of 8r0. What is the order of this reaction

Answers

Answer:

See explanation

Explanation:

Now taking A, we can see that if we double the amount of A while keeping the amount of B constant, the rate of reaction doubles, hence we can write;

2^n = 2^1

hence n =1

For B, when the amount of B is doubled while keeping the amount of A constant, the rate of reaction increases eight times. Hence we can write;

2^n = 8

2^n = 2^3

n=3

Hence this reaction has an overall order of 1 + 3 = 4

So we can write;

rate =k[A] [B]^3

Molecular orbital diagram for Fe.

Answers

ANSWER;

1s22s22p63s23p63d64s2

EXPLANATION;

Molecular orbital diagram for Fe.

In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. We now shift to the 4s orbital where we place the remaining two electrons. After the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d6.

Therefore the Iron electron configuration will be 1s22s22p63s23p64s23d6.

Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written

Therefore we have 1s22s22p63s23p63d64s2

Acid and base

The terms acid and base describe chemical characteristics of many substances that we use daily. Acidic things taste sour. Basic or alkaline things taste soapy. Strong acids are corrosive and strong bases are caustic; both can cause severe skin damage that feels like a burn.  However, mild acids and bases are common and relatively harmless to us.

 2 H2O ⇌ 1 H3O+ + 1 OH-

Examples of bases are sodium hydroxide, calcium carbonate and potassium oxide. A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts.Basic substances react to aqueous solutions by accepting protons, giving away electrons, or releasing hydroxide ions. They neutralize acids by reacting with hydrogen ions to form salts and water. A base that dissolves in water is also known as an alkali.The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.

Explanation:

First, define some important terms.

Mass number: the sum of the nucleons (protons and neutrons) Atomic number: the number of protons

We know the mass number is 9. So, the sum of protons and neutrons is 9.

[tex]mass \ number =9[/tex][tex]protons + neutrons = 9[/tex]

We also know the atoms has 5 neutrons. Therefore, the rest must be protons.

[tex]protons + 5 \ neutrons =9[/tex]

Subtract the 5 neutrons from the overall mass number of 9.

[tex]protons = 9- 5 \ neutrons \\[/tex][tex]protons=4[/tex]

There are 4 protons, so the atomic number is also 4. This atom is beryllium.

Which of the above reactions is an example of combustion of an Inorganic substance? (5 points)

Answers

Answer: 2

Explanation:

A combustion reaction must include O2 as a reactant.

An inorganic substance almost never includes carbon.

So, by process of elimination:

1. Carbon is a reactant = probably not

2. Has O2, no carbon = yes

3. O2 is not a reactant = no

4. Carbon is a reactant = probably not

An example of the combustion of an inorganic substance is:

2 Ca + O₂ ⇒ 2 CaO

We have 4 reactions and we want to determine which is an example of combustion of an inorganic substance.

What is combustion?

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.

What is the difference between organic and inorganic substances?

Organic substances always contain carbon while most inorganic substances do not contain carbon.

Let's consider the following reactions.

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

This is a combustion reaction but C₃H₈ is an organic substance.

2 Ca + O₂ ⇒ 2 CaO

This is an example of the combustion of an inorganic substance.

AgNO₃ + NaCl ⇒ AgCI + NaNO₃

This is not a combustion reaction.

CH₃COOH + 2 O₂ ⇒ 2 CO₂ + 2 H₂O

dipole dipole bonds are covalent bond?​

Answers

Answer:

The polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule.

Explanation:

I have some things to point out:

#1: There is no such thing as "Dipole-dipole bonds", only Dipole-dipole interactions between molecules that share an unequal balance of electrons between their atoms.

#2: Intermolecular forces of attraction such as Dipole-dipole interactions are not considered as covalent bonds. Covalent bonds are rigid and are considered intramolecular forces of attraction (found within the molecule instead of between)
