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 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.

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.

Answer: 6 moles

Explanation:

The balanced equation for this reaction is [tex]2\text{H}_{2}+\text{O}_{2} \longrightarrow 2\text{H}_{2}\text{O}[/tex].

This means that for every 2 moles of water produced, 2 moles of hydrogen are consumed.

Thus, if 6 moles of water are produced, this means 6 moles of hydrogen are consumed.

Answer:

[tex]M_{base}=0.488M[/tex]

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve this problem by firstly writing the chemical reaction between hydrochloric acid and barium hydroxide:

[tex]2HCl+Ba(OH)_2\rightarrow BaCl_2+2H2_O[/tex]

It means there is 2:1 mole ratio of the acid to base, and we are able to write the following mole ratio, then written in terms of volumes and concentrations:

[tex]n_{acid}=2n_{base}[/tex]

Thus, we obtain the following:

[tex]M_{acid}V_{acid}=2M_{base}V_{base}[/tex]

Then, we solve for the concentration of the base and consequently plug in the given data to obtain:

[tex]M_{base}=\frac{M_{acid}V_{acid}}{2V_{base}} \\\\M_{base}=\frac{0.863M*37.2mL}{2*32.9mL}\\\\M_{base}=0.488M[/tex]

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 correct answer is C

Explanation:

light refracts whenever it travels at an angle into a substance with a different refractive index(optical density)

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.
