Answer:B. 0.05 mol/dm3

Explanation:

The hydrogen ion concentration in the solution is 2 mol/dm³

The correct answer to the question is Option D. 2 mol/dm³

We'll begin by calculating the molarity of the solution.

Volume = 25 cm³ = 25 / 1000 = 0.025 dm3

Mole of H₂SO₄ = 0.025 mol

Molarity = mole / Volume

Molarity of H₂SO₄ = 0.025 / 0.025

H₂SO₄(aq) —> 2H⁺(aq) + SO₄²¯(aq)

From the balanced equation above,

1 mole of H₂SO₄ contains 2 moles of H⁺.

Therefore,

1 mol/dm³ H₂SO₄ will also contain 2 mol/dm³ H⁺.

Thus, the concentration of Hydrogen ion in the solution is 2 mol/dm³

The correct answer to the question is Option D. 2 mol/dm³

Answer: State of matter, Subcategory in the metal-metalloid-nonmetal trend, and electrons per shell.

Explanation:

Answer:

It is an amine; it contains a nitrogen atom that will allow nitrogen-hydrogen bonds to form while in water.

Explanation:

The solubility of amines owes largely to the electronegativity difference between nitrogen and hydrogen. Remember that when hydrogen is bonded to highly electronegative element such as nitrogen, intermolecular hydrogen bonding is possible with water molecules. This explains the greater solubility of amines in water.

Ether molecules do have an oxygen atom, however, and engage in hydrogen bonding with water molecules to a lesser extent compared to amines.

Also, amines participate in some acid-base reactions that lead to the formation of diethylammonium hydroxide, an ion which leads to a greater solubility of amines compared to an ether.

Hence, compound A is an amine.

Explanation:

A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly, returning to its original position. But the wave travels along the medium

Answer:

15.26 g of tin

Explanation:

Given that the equation of the process is;

Sn^2+(aq) + 2e ------> Sn(s)

Since 1e = 1F= 96500 C

but q =It

t is in hours so it must be converted to seconds, the SI unit of time

Hence;

119g of tin is deposited by 2 * 96500 C

xg of tin is deposited by 5.29 * 1.30 * 60 * 60

x = 119 * 5.29 * 1.30 * 60 * 60/ 2 * 96500

x = 2946106.8/193000

x= 15.26 g of tin

A current of 5.29 A is passed through a Sn(NO₃)₂ solution for 1.30 hour, the amount of tin plated is 15.26 grams.

Mass of any deposited susbatnce that is obtained by the passing of current will be calculated by using the Faraday's Law as:

W = ECT/F, where

W = required mass of deposited tin

C = current = 5.29 A

T = time period = 1.30hr = 4,680sec

F = faradays constant = 96500C

E = equivalent mass

Equivalent mass will be calculated as:

E = molar mass/charge on atom = 119/2 = 59.5 g/equ

On putting all these values in the above equation, we get

W = (59.5)(5.29)(4680) / 96500

W = 15.26 g

Hence mass of tin is 15.26 g.

Answer:

Aluminum even after being an active metal is used as a structural metal due to its toughness, high strength, lightweight, and resistance to the process of corrosion. It is resistant to corrosion as its reactivity gets suppressed due to the formation of an aluminum oxide film which is protective in nature, on its surface. Passivation is the term for the formation of the protective coating.

Explanation:

In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.

Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.

STP conditions are defined as a pressure of

100 kPa

and a temperature of 0∘C

. Under these conditions for pressure and temperature, one mole of any ideal gas occupies

22.7 L

- this is known as the molar volume of a gas at STP.

So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

Answer: Thus [tex]\Delta H[/tex] for the conversion of gray tin to white tin is -20.9 kJ

Explanation:

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to this law, enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

The final reaction is

[tex]Sn(s, gray)\rightarrow Sn(s, white)[/tex]  [tex]\Delta H=?[/tex]

The intermediate balanced chemical reaction will be,

[tex]Sn(s, gray)+O_2(g)\rightarrow SnO_2(g)[/tex]  [tex]\Delta H^0=-582.78kJ[/tex]    (1)

[tex]Sn(s, white)+O_2(g)\rightarrow SnO_2(g)[/tex]  [tex]\Delta H^0=-580.69kJ[/tex]     (2)    

substarcting (2) form (1) we get

[tex]\Delta H=\Delta H_1-\Delta H_2[/tex]

[tex]\Delta H=-582.78-(-580.69kJ)[/tex]

[tex]\Delta H=-20.9kJ[/tex]
