Explanation:

Replacement  reaction.

Given

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.

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.

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.

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.

The non-metals are boron and carbon. The metal is aluminum and the metalloid is silicon.

Explanation:

non-metal = boron, carbon

metal = aluminum

metalloid = silicon

Non-metal = boron, carbon

Metal = aluminum

Metalloid = silicon

A solid material which is lustrous, hard, shiny, malleable, and sonorous with good electrical and thermal conductivity.

Metal is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity.

A nonmetal is an element that does not have the properties of a metal.

A metalloid is an element having intermediate properties of both metals and nonmetals.

Hence,

Non-metal = boron, carbon

Wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature.

Wood is one of the most common and useful natural materials. It is the main tissue that supports and conducts nutrients in trees and other plants. Wood comes in a variety of colours & grain patterns and is produced by numerous botanical species, comprising both gymnosperms & angiosperms.

Its wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature. Unfavourable weather and unexpected temperatures will have an impact on the wood's strength. Among its attributes are mechanical, chemical, and physical qualities.

Explanation:

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.

Explanation:

im just bored and my friend fell asleep on me :/

Temperature measures the average kinetic energy of particles of the substances. Therefore,  reducing the temperature of chemical reaction reduces  rate of reaction.

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.

C+H₂O⇒CO + H₂ ΔH rxn= -434.7 kJ

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.

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.

The solution with lowest pH are more acidic and those with higher pH values are basic. The given solutions can be ranked from the strongest to weakest acid as Y Z X W.

pH of a solution is the measure of its H+ ion concentration. Mathematically it is the negative logarithm of H+ ion concentration of the solution. The acidic solutions contains more H+ ions.

A pH value of 7 represents a neutral solution. The pH above 7 is basic solution and a solution with pH below 7 is acidic in nature. A pH scale can be used to measure the range.

The pH of 1  and 3 indicates strong acidic solutions and 5 and 6 are weakly acidic . The lowest value of pH indicates highest acidity. Therefore, the correct order is Y Z X W.
