Replacement reaction.
Further explanationGiven
A chemical reaction
AB + C → CB + A
Required
reaction type
Solution
There are several types of reactions that can occur
synthesis: 2 elements combine to form a single product
polymerization: monomers combine to produce a polymer
decomposition: One compound breaks down into 2 components
oxidation : a change in oxidation number
replacement can be divided into 2
single replacement if one element replaces the other elements of a compound
double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds
AB + C → CB + A
If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number
element A undergoes a reduction reaction
element C undergoes an oxidation reaction
So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.

a. temperature change
b. formation of a liquid
c. color change
d. formation of a gas
Answer:
a
Explanation:
uh process of elimination
Temperature change, phase change to liquid or gas are all physical changes not chemical reactions. A color change indicates a chemical reaction has taken place.
What is a chemical change?Chemical changes are taking place by the breaking or making of chemical bonds. It results in the formation of a new product which is having different properties than the initial substances.
Physical changes does not involve any change in chemical bond. Phase changes, change in size, shape, conductivity, solubility etc. are physical changes. A change in temperature phase conversion into gas or liquid are all physical changes.
A change in color indicates that a new product is formed there. For example reddish brown rust is iron oxide formed by the reaction of Fe with oxygen. Therefore, option c is correct.

If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N

A magnesium atom that loses 2 electrons becomes a
A) Positive ion with a smaller radius
B) Positive ion with a larger radius
C) Negative ion with a larger radius
D) Negative ion with a smaller radius
Answer:
A
Explanation:
because the atomic radius reduced by loosing one energy level leading to a positive ion in the resulting ion
The study of chemicals and their bond is called chemistry.
The correct answer is A.
The metals have the property to lose electrons to become stable compounds.
In magnesium, the total number of electrons is 12. In a valance shell, they have 2 electrons.
when they lose or donate the two electrons to the other. The outer shell will be empty and the force of the nucleus remains in the inner shell.
The loss of electrons leads to a decrease in the size of an atom and form positive ions.
Hence, the correct answer is A that is a Positive ion with a smaller radius.

EXPLAIN What is one way that the thermal energy of a system can be changed?
Answer:
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Explanation:
BTW I GOT THE ANSWER FROM KRISTINA
The thermal energy of a system is the amount of heat energy in it.
One way to change thermal energy is by alter the system by introducing a new object to the system.
The thermal energy of a system is calculated using:
[tex]E = \frac 12 mc\theta[/tex]
Assume the mass of the system remains unchanged.
When an object is introduced to the system, the thermal energy becomes:
[tex]E_2 = \frac 12 mc(\theta + \alpha)[/tex]
Where:
[tex]\alpha \ne 0[/tex] --- the temperature of the object.
Expand:
[tex]E_2 = \frac 12 mc(\theta) + \frac 12 mc (\alpha)[/tex]
Substitute: [tex]E = \frac 12 mc\theta[/tex]
[tex]E_2 = E + \frac 12 mc (\alpha)[/tex]
This means that the thermal energy of the system will change by the thermal energy of the object that is being introduced to the system.
Hence, one way the thermal energy can be changed is to introduce a new object (or matter).

law of conservation of matter

Explanation:

Answer: Hope this helps:)
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substances react by following certain laws. These laws are called the laws of chemical combination. Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
List all the layers of the atmosphere and give one SENTENCE description or characteristic for each layers.
Answer:
Troposphere, stratosphere, mesosphere, and thermosphere.
Explanation:
Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Answer:
The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.
Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.
