What is the net ionic equation for the reaction of solid iron with aqueous copper sulfate? (Hint: First use the activity series to write the formula unit equation!)

Answers

Answer 1

Answer: For the answer to the question above,
The reaction of solid iron with aqueous copper sulfate is an example of a single displacement type of reaction which exchanges only the cations of the element and the compound. In this case, the equation is

Fe (s) + CuSO4 (aq) = FeSO4 + Cu (s)

Answer 2

Answer:

Answer:

The net ionic equation for the reaction of solid iron with aqueous copper sulfate:

$Fe(s)+Cu^(2+)(aq)\rightarrow Fe^(2+)+(aq)+Cu(s)$

Explanation:

Solid iron = Fe

Copper sulfate = $CuSO_4$

$Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)$

In an aqueous solution of copper sulfate we have copper (II) ions and sulfate ions.

$CuSO_4(aq)\rightarrow Cu^(2+)(aq)+SO_4^(2-)(aq)$

In an aqueous solution of ferrous sulfate we have ion (II) ions and sulfate ions.

$FeSO_4(aq)\rightarrow Fe^(2+)+(aq)+SO_4^(2-)(aq)$

$Fe(s)+Cu^(2+)(aq)+SO_4^(2-)(aq)\rightarrow Fe^(2+)+(aq)+SO_4^(2-)(aq)+Fe^(2+)+(aq)$

Cancelling out the common ions from both sides, we get the net ionic equation:

$Fe(s)+Cu^(2+)(aq)\rightarrow Fe^(2+)+(aq)+Cu(s)$

What is the major difference between a solution and an ordinary mixture?

Answers

An ordinary mixture can be separated without using chemicals, a solution cannot.

The major difference between a solution and an ordinary mixture is that solution is homogeneous and an ordinary mixture is heterogeneous.

Which of these changes most likely results in an increase in the volume of a gas? A0 Decreasing the pressure on the gas. B) Cooling the gas. C) Removing some of the gas form the sample.

Answers

The answer is (B) decreasing the pressure on the gas, as Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure.

Removing some of the gas from the sample is the change that most likely results in a decrease in the volume of the gas, rather than an increase. This is because decreasing the amount of gas in the sample will reduce the total volume of the gas.

On the other hand, cooling the gas will typically cause it to contract, reducing its volume. Similarly, decreasing the pressure on the gas will typically cause it to expand and increase in volume.

State in term of molecular polarity why ethanol is soluble in water

Answers

Explanation:

As we all know that like disolves in like solvent.

Here both water and Ethanol are polar. Hence Ethanol soluble in water.

Moreover, both forms intermolecular hydrogen bonds. It enhances the solubility of ethanol.

Both water and Ethanol are called as associate liquids. Hence solubility is more.

Alcohols have higher boiling point than other hydrocarbons due to their polarity and from the fact that they form very strong intermolecular hydrogen bonding. This is due to the large difference in their electronegativity that forms between the oxygen and the hydrogen atom.

1) 0.143 g Mg into atoms
2) 0.101 kg Ti into atoms

Answers

Answer:

The answer to your question is below

Explanation:

1) 0.143g of Mg into atoms

- Look for the atomic number of Magnesium in the Periodic table

Atomic number = 24.31 g

-Use the Avogadro's number to find the number of atoms

24.31g ------------------- 6.023 x 10²³ atoms

0.143 g ----------------- x

x = (0.143 x 6.023 x 10²³) / 24.31

x = 8.613 x 10²² / 24.31

x = 3.54 x 10²¹ atoms

2) 0.101 kg of Ti into atoms

-Look for the atomic number of Titanium in the Periodic table

Atomic number = 47.87 g

-Use the Avogadro's number to find the number of atoms

47.87 g --------------------- 6.023 x 10²³

101 g ---------------------- x

x = (101 x 6.023 x 10²³) / 47.87

x = 6.08x 10²⁵ / 47.87

x = 1.27 x 10²⁴ atoms
