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:

Smashing the cube into pieces

Explanation:

The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.

The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.

The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.

It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.

The amount of reactants, the temperature, and the catalyst all influence the reaction rate.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.

The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.

Thus, C is the correct answer.

#SPJ2

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: During a phase change, such as melting or boiling, the kinetic energy increases.

Explanation:

Kinetic energy is the energy obtained by the molecules of a substance due to their motion.

When phase change such as melting or boiling takes place then it means heat is absorbed by the substance. As a result, their molecules more even more rapidly from one place to another due to which more number of collisions take place.

Hence, a change in phase of substance occurs as kinetic energy increases in melting or boiling process.

Thus, we can conclude that during a phase change, such as melting or boiling, the kinetic energy increases.

Answer:

43.1atm is the pressure using gas law and 27.2atm using Van der Waals Law.

Explanation:

Ideal gas law is:

PV = nRT

Where P is pressure in atm

V is volume = 4.00L

n are moles of the gas (For chlorine Molar Mass: 70.90g/mol):

500g * (1mol / 70.90g) = 7.052 moles

R is gas constant = 0.082atmL/molK

T is absolute temperature = 25°C + 273 = 298K

To solve the pressure, P:

P = nRT/V

P = 7.052mol*0.082atmL/molK*298K / 4.00L

P = 43.1atm is the pressure using gas law.

Van der Waals equation is:

[tex]P + a(\frac{n}{V})^2 * (V-nb) = nRT[/tex]

Where a is 6.58L²atm*mol⁻²

b = 0.056Lmol⁻²

Solving for pressure:

[tex]P + a(\frac{n}{V})^2 = \frac{nRT}{(V-nb)}[/tex]

[tex]P = \frac{nRT}{(V-nb)}-a(\frac{n}{V})^2[/tex]

[tex]P = \frac{7.052mol*0.082atmL/molK*298K}{(4.00L-7.052mol*0.056L*mol)}-6.58L^2mol^{-2}(\frac{7.052mol}{4.00L})^2[/tex]

P = 172.323 / 3.6051 - 20.4866

P = 27.2atm using Van der Waals Law

Step 2: Determine the molar mass of cyanocobalamin

There is one atom of cobalt in every molecule of cyanocobalamin, or what is the same, there is 1 mole of atoms of Co in every mole of molecules of cyanocobalamin. Given the molar mass of Co is 28.01 g/mol, the molar mass of cyanocobalamin is:

100 g B12/4.34 g Co × 28.01 g Co/1 mol Co × 1 mol Co/1 mol B12 = 645 g/mol
