Answer:

Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.

Explanation:

Answer:

Gases can dissolve in water. The dissolving of a gas in water depends on the interaction between the molecules of the gas and the water molecules. The amount of gas that can be dissolved in water depends on the temperature of the water. More gas can dissolve in cold water than in hot water.

Answer: substances formed as a result of chemical reaction are called PRODUCTS.

Explanation:

A chemical reaction can be defined as a reaction in which substances known as the REACTANTS makes or breaks it's bonds to form another substance usually referred to as the PRODUCT. Usually, a new substance which is referred to as the product that is formed is different from the original reacting substances. Some of the characteristics of a chemical reaction include:

--> colour change,

--> heat production,

--> precipitation

The rate at which these chemical reaction occurs depends on some factors such as pressure, temperature and concentration of the reactants

There are different examples of chemical reaction which includes:

--> Rusting of iron: this occurs when iron and oxygen combines to form a mixture of iron oxides, which is the product of the chemical reaction.

--> The burning of magnesium in air: in this Chemical reaction, magnesium reacts with oxygen to form magnesium oxide which is the product of the chemical reaction.

2Mg(s) + O2(g) △→ 2MgO(s)

--> Production of table salt: this is formed from the reaction of sodium and chloride to give sodium chloride as the product of the chemical reaction.

Therefore in a chemical reaction, no atom is destroyed or created but a new PRODUCT is formed from reactants.

It is a type of of addition combination chemical  reaction where in bromine adds across the double bonds of butane whose chemical equation is C₄H₈ +Br₂[tex]\rightarrow[/tex]C₄H₈Br₂.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:??

Explanation:

To solve such this we must know the concept of double displacement reaction. Therefore, copper (Cu) and silver (Ag) would not liberate hydrogen from dilute tetraoxosulphate(vi) acid.

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.

Copper (Cu) and silver (Ag) would not liberate hydrogen because they are less reactive than hydrogen since their standard reduction potential is higher.

Therefore, copper (Cu) and silver (Ag) would not liberate hydrogen from

dilute tetraoxosulphate(vi) acid.

Answer: The concentration of [tex]Cu(OH)_{2}[/tex] is  0.369 M.

Explanation:

Given: [tex]V_{1}[/tex] = 72.4 mL,     [tex]M_{1}[/tex] = ?

[tex]V_{2}[/tex] = 47.8 mL,       [tex]M_{2}[/tex] = 0.56 M

Formula used to calculate the concentration of [tex]Cu(OH)_{2}[/tex] is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\M_{1} \times 72.4 mL = 0.56 M \times 47.8 mL\\M_{1} = \frac{0.56 M \times 47.8 mL}{72.4 mL}\\= 0.369 M[/tex]

Thus, we can conclude that the concentration of [tex]Cu(OH)_{2}[/tex] is  0.369 M.

Round to least sig fig (390 ml)

5.0

Answer:

0.895 mL

Explanation:

Using the formula;

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (mL)

V2 = final volume (mL)

According to the information provided in this question;

C1 = 15.54M

V1 = ?

C2 = 2.28M

V2 = 6.1 mL

Using C1V1 = C2V2

V1 = C2V2 ÷ C1

V1 = (2.28 × 6.1) ÷ 15.54

V1 = 13.908 ÷ 15.54

V1 = 0.895 mL

Answer: The final volume of this solution is 0.204 L.

Explanation:

Given: Molarity of solution = 2.2 M

Moles of solute = 0.45 mol

Molarity is the number of moles of solute present divided by volume in liters.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}[/tex]

Substitute the values into above formula as follows.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\2.2 M = \frac{0.45}{Volume}\\Volume = 0.204 L[/tex]

Thus, we can conclude that the final volume of this solution is 0.204 L.
