The mass percent of oxygen in Nickel(\(III\))sulfate is \(23.68\) percent.

At first, we look up the atomic masses for the element from the periodic table.

The atomic masses are found to be:

Next, we determine how many grams of each element are present in one mole of \(Ni_{2}(SO_{4})_{3}\)

The mass of one mole  \(Ni_{2}(SO_{4})_{3}\) is:

\(117.4g+96g+192g=405.4g\)

So, The mass percent of oxygen \(=(96g/405.4)*100=0.2368*100%\\\)

                                                    \(=23.68 %\) percent.

Explanation:

the change of oxygen from solid to liquid would be that at the solid phase the color would be light blue and changes to colorless on the liquid phase

When oxygen transitions from solid to liquid, its colour changes from bright blue in the solid state to colourless in the liquid state.

The periodic table's Group 16 (also known as the oxygen group) contains the nonmetallic chemical element oxygen (O). Oxygen is a colourless, odourless, and tasteless gas that is necessary for all living things. Animals take it up and then change it into carbon dioxide, which plants then use as a source of carbon and release the oxygen back into the atmosphere.

As well as reactions that remove elements from their combinations with one another, oxygen may react with nearly any other element to produce compounds. These reactions, which are frequently accompanied by the development of heat and light, are known as combustions. Water is the most significant component.

Therefore, when oxygen transitions from solid to liquid, its colour changes from bright blue in the solid state to colourless in the liquid state.

Answer: The size of actual bed is 75 inches

Explanation: Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.

Scale= original dimension/miniaturised dimension

Given that scale is 1:25

It means that every 1 inch on paper would correspond to 25 inches in reality.

The length of the model bed= 3 inches

Hence, the length of the original bed is 25*3 = 75 inches

Explanation:

When hydrogen bromide (HBr) is added to 2-methylbut-2-ene ((CH3)2CCHCH3), an electrophilic addition reaction takes place, where the π bond of the alkene is broken, and the hydrogen and bromine atoms are added to the resulting carbocation.

The reaction proceeds through a Markovnikov addition, where the hydrogen atom attaches to the carbon atom with the greater number of hydrogen atoms.

In this case, the initial addition of HBr to 2-methylbut-2-ene leads to the formation of a primary carbocation, as the positively charged carbon atom only has one alkyl group attached to it. The primary carbocation is relatively unstable, and it can undergo a rearrangement to form a more stable secondary carbocation.

The major product that is typically obtained is the 2-bromo-2-methylbutane. The hydrogen atom from HBr adds to the carbon with three hydrogen atoms (the more substituted carbon), resulting in the formation of a secondary carbocation.

On the other hand, a minor product is also formed, which is 3-bromo-2-methylbutane. This product arises from the addition of HBr to the primary carbocation, which is less stable. Although the primary carbocation is less favored, it can still be formed and lead to the formation of the minor product.

In summary, the addition of HBr to 2-methylbut-2-ene yields two products: the major product is 2-bromo-2-methylbutane, resulting from the addition of HBr to the more stable secondary carbocation, and the minor product is 3-bromo-2-methylbutane, originating from the less stable primary carbocation.

Explanation:

The esterification reaction is a name reaction in organic chemistry, where it is called Fischer esterification. In addition, when the reverse reaction is promoted by using a base, it is called a saponification reaction.

Answer:

The esterification reaction is a name reaction in organic chemistry, where it is called Fischer esterification. In addition, when the reverse reaction is promoted by using a base, it is called a hydrolysis reaction.

Explanation:

The Fischer esterification is a type of organic reaction that involves the conversion of a carboxylic acid and an alcohol into an ester and water, catalyzed by an acid catalyst. This reaction is named after its discoverer, Emil Fischer, a German chemist who first described the reaction in 1895.

The general equation for Fischer esterification is:

Carboxylic acid + Alcohol → Ester + Water

For example, the reaction between acetic acid and ethanol to form ethyl acetate (a commonly used solvent and flavoring agent) can be represented as follows:

CH3COOH + C2H5OH → CH3COOC2H5 + H2O

The Fischer esterification is an important reaction in organic chemistry because esters are important compounds in a variety of applications, including the food industry (as flavorings and fragrances), the pharmaceutical industry (as intermediates in the synthesis of drugs), and the polymer industry (as monomers).

When the reverse reaction of Fischer esterification is promoted by using a base, it is called a hydrolysis reaction. Hydrolysis is the process of breaking down a compound by adding water. In the case of esters, hydrolysis occurs when the ester bond is broken by the addition of water, yielding a carboxylic acid and an alcohol.

The general equation for hydrolysis of an ester is:

Ester + Water → Carboxylic acid + Alcohol

For example, the hydrolysis of ethyl acetate can be represented as follows:

CH3COOC2H5 + H2O → CH3COOH + C2H5OH

Hydrolysis of esters is an important reaction in organic chemistry because it is a common route for the degradation of esters in nature, as well as in many industrial processes where it is used for the production of carboxylic acids and alcohols.

Taking into account the definition of density, the length of each side of the cube is 4 cm.

In other words, density is a quantity that allows to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is:

density= mass÷ volume

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

2 g/cm³= 128 g÷ volume

Solving:

2 g/cm³× volume= 128 g

volume= 128 g÷ 2 g/cm³

volume= 64 cm³

The volume of a cube is equal to the measure of its side to the cube. That is to say:

Volume = side x side x side = side³

So, the length of each side of the cube can be calculated as:

64 cm³= side³

∛64 cm³= side

4 cm= side

In summary, each side of the cube has a measure of 4 cm.

Explanation:

Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.

To prepare a 0.12 M solution of FeCl₃, the amount of solid FeCl₃ to be dissolved in a given volume of solvent will be 9.72 grams.

Given,

Molarity of FeCl₃ (M)= 0.12 M

The molecular weight (m) of FeCl₃ is  = 162 gm

The volume of the solution (V) to be prepared is =500 ml

The amount of FeCl₃ to be dissolved to make a 0.12 M solution is= x

So,

MV= x ÷ m × 1000

0.12× 500 = x ÷ 162 × 1000

x = 60 × 162 ÷ 1000

x= 9.72 gm

So 9.72 grams of FeCl₃ is dissolved to make 500 ml of 0.12 M solution.

For preparing 0.4 M HCl from 4M HCL:

If we need to make 500 ml of solution with 0.4M of HCL, then we use the formula:

M₁V₁= M₂V₂

0.4 × 500= 4 × x

x= 50 ml

So 50 ml of 4M HCL is taken to make 0.4 M HCL.
