Answer:

Single displacement reaction.

Explanation:

Hello,

In this case, the mentioned chemical reaction turns out:

$Fe^{3+}+CuSO_4\rightarrow Fe_2(SO_4)_3+Cu^{2+}$

Therefore, as the iron is exchanged with the copper, iron (III) sulfate is yielded and copper (II) cations are released to the aqueous solution.

Best regards.

Answer:

The answer to your question is Single replacement

Explanation:

Types of reaction in Chemistry

Synthesis two or more reactants combine to produce one single product

Decomposition one reactant splits producing two or more products

Single replacement One element replaces a similar one in a compound.

Double replacement Two compounds interchange their cations and anions.

Combustion one compound reacts with oxygen to produce carbon dioxide and water.

Reaction given

Fe⁺² + CuSO₄ ⇒ Cu + FeSO₄

This is a single replacement reaction

How many moles of br2(l) (mm = 159.80 g/mol) are in 13.9 ml of liquid bromine? the density of br2(l) is 3.12 g/ml?

diamong [38]

Answer:

Moles = 0.271 mol

Solution:

Step 1: Calculate Mass of Br₂ as;

Density = Mass ÷ Volume

Solving for Mass,

Mass = Density × Volume

Putting values,

Mass = 3.12 g.mL⁻¹ × 13.9 mL

Mass = 43.36 g

Step 2: Calculate Moles of Br₂ as;

Moles = Mass ÷ M.Mass

Putting values,

Moles = 43.36 g ÷ 159.80 g.mol⁻¹

Moles = 0.271 mol

Which of the following liquids will have the highest surface tension?

rjkz [21]

Water has highest surface tension

Answer: Option (c) is correct

<u>Explanation:</u>

There are molecules present in every liquid. Attachment of these molecules with each other gives rise to surface tension. It is the result of intermolecular forces. It is due to surface tension the insects float on a liquid.

The water has the highest surface tension. it is because molecules present on the surface of the water are held together by very strong hydrogen bonds. There is high attraction among the molecules of water.

. The net ionic equation for the reaction that occurs during the titration of nitrous acid with sodium hydroxide is (a) HNO2 Na

hjlf

Answer:

$H^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}$

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Only the species which are present in aqueous state dissociate.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

(a)

The balanced molecular equation will be,

$HNO_2_{(aq)}+NaOH_{(aq)}\rightarrow H_2O_{(l)}+NaNO_2_{(aq)}$

The complete ionic equation in separated aqueous solution will be,

$H^+_{(aq)}+NO_2^-_{(aq)}+Na^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}+Na^+_{(aq)}+NO_2^-_{(aq)}$

In this equation the species present are, $Na^+\text{ and }NO_2^-$ are the spectator ions.

Hence, the net ionic equation contains specie is

$H^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}$

21.7 mL of gas at 98.8 kPa is allowed to expand at constant

IRISSAK [1]

Answer: 40.68 kPa

Explanation:

Given that,

Original volume of gas V1 = 21.7 mL

Original pressure of gas P1 = 98.8 kPa

New volume of gas V2 = 52.7 mL

New pressure of gas P2 = ?

Since pressure and volume are given while temperature is constant, apply the formula for Boyle's law

P1V1 = P2V2

98.8 kPa x 21.7 mL = P2 x 52.7L

2143.96 kPa L = 52.7 L x P2

P2 = 2143.96 kPa L / 52.7 L

P2 = 40.68 kPa

Thus, the new pressure of the gas is 40.68 kPa.
