6.	In the below given figure 'P' refers to which process. Identify and mention its type and anytwo changes involved in the whole process. (Reversible and Irreversible)
Answer» Answer: What is change? Well in chemistry, change can be explained on physical grounds. Changes are very random or uncertain phenomena, it can be better or worse depending on your view. Every day we see DIFFERENT objects CHANGING around us like melting of ice, cooking of food etc. In some cases, you get back the original substance and in some, you won’t get it back. Some changes are slow while some are fast, some are natural and some are man-made. You will find that many changes are taking place around us for e.g. growing of plants in your balcony, SOMETIMES there is a change in colour and sometimes you will find drying of leaves. Reversible And Irreversible Changes Reversible Changes Any changes which can be reversed or are a temporary conversion are known as reversible changes. The reactions which are reversible are called reversible reactions. In this reaction, one substance is modified into another FORM but a new compound is not formed. Processes such as melting, boiling, evaporation, freezing, condensation, dissolution are reversible changes. Few examples are melting of wax, freezing of ice, boiling water which evaporates as steam and condenses back to water. Reactions are an interaction of two or more compounds called REACTANTS to produce a product(s). In a reversible reaction, reactants and products formed are connected by a two-way arrow (⇌). This means reactants can be obtained back from the products. Consider the reaction below, A +B ⇌ C + D Here, A and B are two reactants which react to give C and D. The two-headed arrow indicates that reaction is reversible and the reactants, A and B can be obtained from C and D. Irreversible changes In contrast to reversible changes, irreversible changes are permanent changes. Reactants react to form an entirely new compound and cannot be reversed. Heating, burning, mixing, powdering are few processes which cause irreversible changes. A common observable example is the cooking of raw egg which can’t be converted back to its original form. Ash obtained by the combustion of paper or any other substances is another example. When a reaction is taking place in a unidirectional way such reactions are called irreversible reactions. In such reactions in a period of time reactants react completely to form a product. Here reaction is denoted by a one-way arrow (→). For example, A → B +C Here, A is the reactant which is completely converted into products B and C which do not react to form Explanation:

Reversible And Irreversible Changes

Reversible Changes

Any changes which can be reversed or are a temporary conversion are known as reversible changes. The reactions which are reversible are called reversible reactions. In this reaction, one substance is modified into another FORM but a new compound is not formed. Processes such as melting, boiling, evaporation, freezing, condensation, dissolution are reversible changes. Few examples are melting of wax, freezing of ice, boiling water which evaporates as steam and condenses back to water.

Reactions are an interaction of two or more compounds called REACTANTS to produce a product(s). In a reversible reaction, reactants and products formed are connected by a two-way arrow (⇌). This means reactants can be obtained back from the products.

Consider the reaction below,

A +B ⇌ C + D

Here, A and B are two reactants which react to give C and D. The two-headed arrow indicates that reaction is reversible and the reactants, A and B can be obtained from C and D.

Irreversible changes

In contrast to reversible changes, irreversible changes are permanent changes. Reactants react to form an entirely new compound and cannot be reversed. Heating, burning, mixing, powdering are few processes which cause irreversible changes. A common observable example is the cooking of raw egg which can’t be converted back to its original form.

19.	¡)different atomic Mass unit.¡¡) what is the numerical value of mole.¡¡¡) name the element present in oxide ion.please answer me
Answer» Answer: 1. The ATOMIC mass is useful in chemistry when it is paired with the mole CONCEPT: the atomic mass of an element, MEASURED in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. 2. One mole contains exactly 6.022 140 76 x 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in the unit mol–1 and is called the Avogadro number. 3. An oxide (/ˈɒksaɪd/) is a chemical compound that contains at least one oxygen ATOM and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– (molecular) ion. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

A solution has 50g of salt in 320g of water. Calculate the mass percent of the salt in thesolution.

Answer»

Answer:

Mass of solute - NACL =50gm

Mass of solvent - WATER =320gm

Mass of solution =(50+320) gm

=370gm

Concentration in terms of Mass by mass percentage =mass of solute /mass of solution *100

=40/360*100%=0.1081081081%
