The reactants and products parts of a chemical equation must be balanced.

A chemical reaction is said to be balanced when the number of atoms of each element on both sides of the equation are the same.

A chemical equation consists of the reactants and the products, hence, the number of atoms on both sides must be equal for the equation to be balanced.

Therefore, the reactants and products parts of a chemical equation must be balanced.

crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.

Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

Answer:

Crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Sugar and salt are two mixtures that can be seperated by crystallization

Answer:

C2H4 + 3O2---> 2CO2 + 2H2O

Explanation:

The volume of the gas is directly proportional to the no. of moles of the gas at constant temperature and pressure.

So Volume of O2 : Volume of CO2 = 300: 200

= 3:2

So we can add 3 and 2 stoichiometric coefficients to O2 and CO2 respectively.

Then we can see that out of total 3×2 atoms of O, 2×2 atoms of O have been incorporated into CO2. Therefore the remaining 2 O should be in the H2O ( during complete combustion of hydrocarbon we get CO2 and H2O as products)

So we can add 2 in front of H2O..

Then calculate the total no. of C and H atoms in the products side to find the no. of C and H atoms in the hydrocarbon.

C=2

H=4

So the hydrocarbon burnt has the formula C2H4.

To solve such this we must know the concept of combustion reaction. Therefore, The balanced chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

Combustion reaction is a reaction in which a substance, basically hydrocarbons burns in presence of oxygen to produce carbon dioxide and water.

At constant temperature and pressure, the number of moles of the gas directly relates to the volume of the gas.

Volume of O[tex]_2[/tex]: Volume of CO[tex]_2[/tex]

= 300: 200

= 3:2

The chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

Therefore, the chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

Answer:

complementary colour

Explanation:

The complementary colors are used for the light that is transmitted when complex ions absorb wavelength of visible light.

Complementary colors are color pairs that cancel each other whenever combined and mixed, resulting in a grayscale color either white or black. They offer the most contrast for the those two hues when put adjacent to each other. Colors that are complementary are sometimes known as "opposite colors."

Light, often known as visible light, is electromagnetic radiation that falls within the region of the electromagnetic spectrum which the human eye can perceive.

Therefore,  the complementary colors are used for the light that is transmitted when complex ions absorb wavelength of visible light.

A calculated field will appear in the field list window, but will not take up space in the source data. In the example shown, a calculated field called "Unit Price" has been created with a formula that divides Sales by Quantity. The pivot table displays the calculated unit price for each product in the source data.

Explanation:

The PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.

Calculated fields are defined as the fields whose values are determined by other fields' values and perhaps external sources. Data from other fields can be calculated using calculated fields. Calculating the sum of two fields is a simple example, but more complicated calculations, such averaging values from multiple tables or even gaining access to external data, are theoretically feasible.

PivotTable Field List is defined as the Areas part of the Field List allows you to organize the fields wherever you like. It features a field section where you select the fields you wish to display in your PivotTable. Using a pivot table is an interactive method for quickly summarizing enormous amounts of data.

Thus, the PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.

Answer:

ZnBr2

Explanation:

KNO3 + LiOH -------> no reaction

This is because KNO3 and LiOH completely ionize.in water and form neutral solutions.Since both are neutral no reaction occurs

NH4Cl + LiOH -----> NH3 (aq) + H2O (l) + LiCl(aq)

None of the above products are precipitates

Ca(C2H3O2)2 + 2LiOH -----> Ca(OH)2 (aq) + 2LiC2H3O2 (aq)

ZnBr2 + 2LiOH -----> Zn(OH)2 (s) + LiBr2 ( aq)

Zn(OH)2 thus formed is a white precipitate

However when excess LiOH is added Zn(OH)2 precipitate will dissolve to give a clear solution of Li2ZnO2 .

You can remember this by the fact that Na,K,Rb,Cs,Ca,Sr,Ba hydroxides are soluble in water and all other hydroxide are precipitated in water

Zn(OH)2 (s) + 2 LiOH ------> Li2ZnO2(aq) + 2 H2O ( l)

The only compound that will form a precipitate with LiOH would be ZnBr2

These are double displacement reactions in which precipitates are produced. Precipitates are insoluble solids formed from the combination of ions in aqueous solutions.

In this case, a reaction between LiOH and ZnBr2 would be as follows;

2LiOH + ZnBr2 ----------> 2LiBr + Zn(OH)2 (s)

Zn(OH)2 is an insoluble salt and will precipitate out in the solution.
