What type of reaction does this equation represent? 2i4o9(s) → 4i2(s) + 9o2(g)

This type of reaction is a decomposition reaction, where a starting compound breaks, or decomposes, into two or more different compounds.

Redox reaction/displacement reaction Explanation: Zn + 2AgNO3> Zn(NO3)2+ 2Ag Let us consider the change in oxidation number from left to right Oxidation number of zinc changed from 0 to +2 Oxidation number of silver changed from +1 to 0 Zinc was oxidized while silver was reduced. This shows a redox process Also Zinc displaced silver because silver is below zinc in the a electrochemical series of metals. That is, the electrode potential of zinc is more negative than that of silver hence it can displace silver from its salt.

The given reaction is a type of substitution reaction. Explanation: Addition reaction is defined as the chemical reaction in which more atoms are added to the given compound. No atom is lost during this particular reaction. In organic chemistry, unsaturated hydrocarbons (alkenes and alkynes) shows thsi type of reaction.
Substitution reaction is defined as the chemical reaction in which one atom replaces the other atom from a compound.  In organic chemistry, this reaction is favoured by saturated hydrocarbons (alkanes) only. Hydrogenation reaction is defined as the chemical reaction in which hydrogen atoms are increased in a given compound. This is more favoured by alkenes and alkynes (unsaturated hydrocarbons). The given chemical reaction follows: In the above reaction, bromine is substituting hydrogen from methane molecule to form methane bromide. So, the above reaction is a substitution reaction.

Answer 6


Answer 7

Answer : The given equation represents “Substitution reaction” of alkanes Explanation : The given reaction is, To find out the type of reaction, we need to look at the reactants and products involved in the reaction CH₄ is an alkane known as methane and Br₂ is bromine which belongs to halogen family. During the reaction , we can see that one of the H atoms of methane is substituted by Br to form a product CH₃Br. Therefore this is a “substitution reaction of alkanes” Since a hydrogen atom gets replaced by a halogen atom, it is also termed as “halogenation of alkanes”

The answer to your question is Synthesis and Endothermic Explanation: Balanced chemical reaction                H₂  +  F₂   ⇒   2HF  + 546 kJ Chemical reactions can be classified in different ways, so I suggest two names of this reaction. 1.- This is a synthesis reaction because two different reactants form a new  compound. 2.- This is an endothermic reaction because it was needed  to supply 546 kJ of energy so that the reaction proceeds.

What type of reaction does this equation represent?

In this equation, the variable y represents the height of a person in meters above sea level. If x represents the distance from the ground to the person’s head, what is the value of y?

The first equation

The first equation represents the displacement of an object as a result of an applied force. It can be used to calculate the magnitude and direction of an applied force, and can also be used to calculate the work done on an object as a result of an applied force.

The second equation

The second equation is used to represent the mathematical relationship between two quantities. It can be used to calculate one quantity from the other, or to find the difference between two quantities.

This equation is known as the law of reaction, and it states that the rate of a chemical reaction is proportional to the amount of catalyst present. Without a catalyst, reactions tend to occur slowly and at low rates. With a catalyst, reactions can occur quickly and at high rates.

This equation can be used in many different contexts, including science, engineering, and mathematics. It is also used in everyday life, for example when buying something online.

The third equation

This equation represents the reaction that takes place when hydrogen and oxygen combine. This reaction is called combustion, which is the process of converting one type of molecule into another. In this equation, the two atoms are combining to create heat and water.

The fourth equation

The fourth equation represents the reaction between two compounds. In this equation, A and B are the reactants, and C is the product. The equation can be written in either forward or reverse form, depending on whether the reactant is represented before or after the product.

In forward form, A reacts with B to produce C:

In reverse form, C is produced by B reacting with A:

The fifth equation

This equation represents the change in electrical potential energy between two charges. It is used in physics to calculate the release of energy as a result of an interaction between charged particles.

The equation can be used to calculate the amount of energy released when two electrons collide. This reaction releases energy in the form of heat. It is also used to calculate the potential difference between two charges.


The equation represents the change in momentum of an object as a result of a force applied to it.
