A chemical reaction that has the general formula of AB + C → CB + A is best classified as a
synthesis
polymerization
decomposition
oxidation
replacement
reaction.
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.

If you leave your home at noon, and the speed limit is 50 km/h on the highway, what is the approximate time will you get to Atlantic City if Atlantic City is 150 km away? (obeying the speed limit of course)
Answer:
The time you will get to Atlantic City is 3 pm
Explanation:
Given;
speed limit, v = 50 km/h
distance to be traveled, d = 150km
The time of the motion is given as;
time = distance / speed
t = (150 km) / (50 km/h)
t = 3 hours
Thus, if you leave your home at noon, the time you will get to Atlantic City is given as;
time to get home = 12 pm + 3hours = 3 pm
Therefore, the time you will get to Atlantic City is 3 pm

Full question: Uranium is an element that is often used in nuclear power plants. Uranium atoms are very large, and the substance can be dangerous if it is not carefully contained. What is true about all uranium atoms?Answer:
They each have the same number of protons
Explanation:
All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234
Which of the following are common decomposers? (Select all that apply) fungi, ferns, bacteria, viruses, grasses
Answer:
Fungi, bacteria, ferns,
Explanation:
bacteria Fungi Ferns are important. decomposers,
I hope it helps you.
There are basically four different categories of decomposers: fungi, insects, earthworms, and bacteria. Fungi, ferns and bacteria are common decomposers.
What are decomposers ?Decomposers are organisms that disintegrate rotting or dead species; they carry out decomposition, a process only some kingdoms, like fungi, are capable of.
The primary decomposers in nature are fungi, which destroy organic material that would otherwise not be recycled.
Scavengers and decomposers are the two different categories of decomposers. Animals called scavengers hunt down dead plants or animals and consume them. They cut them into small pieces when they eat them.
Each contributes to the food recycling process differently. To transform dead plants or animals into simple substances, fungi release compounds. Some of these elements are absorbed by them for growth, while others go into the soil.
Thus, Fungi, ferns and bacteria are common decomposers.

What happens when you put an ice-pop outside? This is for the people who don’t know
Answer:
It melts
Explanation:
Answer:
It melts?
Explanation:
why can fluids flow but solids can’t?
Answer:
Fluids can flow because their molecular structure is different. Instead of being tightly packed, like a solid, there are fewer molecules per unit in a liquid than a solid. This gives the molecules of a liquid space to move around, and it flows because liquids take the shape of their container(s). These molecules usually tend to bump into each other and this causes the liquid to move as well
Answer:
Because the particles don't move, solids have a definite shape and volume, and can't flow. LIQUIDS - This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.

How can you use a chemical reaction to remove a contaminant from a solution?
Answer:
reverse osmosis
Explanation:
Water treatment is often complicated because it deals with the chemical makeup of the water, which varies widely. The first step is to determine what contaminants should be removed. Unfortunately, this is not always a straightforward process. Many contaminants make themselves known in obvious ways, such as iron or hydrogen sulfide, which can cause taste and odor issues. Other contaminants, such as arsenic or pesticides, are only uncovered through a sophisticated laboratory analysis.
It is important to test the water so that the right type of treatment system can be selected. Keep in mind, however, that more than one analysis may be necessary to get a baseline because water quality fluctuates. More information on possible contaminants in a specific area can be obtained by talking to residents, the local health department, the water department, or the state geological society. In addition, your laboratory should be able to recommend appropriate tests based on a customer’s concerns and the information provided about the water source. It is important not only to address customers’ concerns but also to educate them about potential contaminants they may not have considered.
Using principles of atomic structure, explain why the atomic radius of Te is less than the ionic radius of Te2− . Photoelectron spectroscopy data for the 1s sublevel of Te and the 1s sublevel of O are represented below. In terms of Coulomb's law and atomic structure, explain why the peak for O is positioned so far to the right of the peak for Te .
Answer:
See explanation
Explanation:
Let us recall that a negative ion is formed by addition of electrons to an atom. When electrons are added to the atom, greater interelectronic repulsion increases the size of the Te^2− hence it is greater in size than Te atom. Therefore, the ionic radius of Te^2− is greater than the atomic radius of Te.
In the second question, oxygen is positioned so far to the right because it has a far smaller nuclear charge compared to Te. Hence in the PES spectrum, the 1s sublevel of oxygen lies far to the right of that of Te.
Using principles of atomic structure, the reason why the atomic radius of Te is less than the ionic radius of Te²− is because of the Electrostatic force of repulsion between the negatively charged electrons of Te²- thereby causing the ion to be bigger than the neutral atom.
We must remember that negative ions are formed as a result of the addition of electrons to an atom.On this note, the electrostatic force of repulsion between the negatively charged electrons of Te²- ion becomes greater. Hence, the Te atomic radius is less than the ionic radius of the Te²- ion.By considering the second scenario, the element oxygen is positioned so far on the right because it has a very much smaller nuclear charge compared to Te.
As a result, in the PES spectrum, the 1s sublevel of oxygen lies far to the right of the 1s sublevel of Te.

how does reducing the temperature of chemical reaction affect the rate at which it occurs?
Answer:
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions.

Temperature measures the average kinetic energy of particles of the substances. Therefore, reducing the temperature of chemical reaction reduces rate of reaction.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
When the temperature is reduced, the molecules move more slowly and collide less. The reaction's pace is slowed as the temperature drops. When the pressure is increased, the molecules have much less area to travel in. The number of collisions rises as the density of molecules increases.
Therefore, reducing the temperature of chemical reaction reduces rate of reaction.
