A 25 cm sample of dilute sulfuric acid contains 0.025 moles of the acid.
What is the hydrogen ion concentration in the solution?
A. 0.2 mol/dm3
B. 0.05 mol/dm3
C. 1.00 mol/dm3
D. 2.00 mol/dm3

Answers

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 of H₂SO₄ =?

Molarity = mole / Volume

Molarity of H₂SO₄ = 0.025 / 0.025

Molarity of H₂SO₄ = 1 mol/dm³

Finally, we shall determine the concentration of Hydrogen ion in the solution.

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

How many mL of O2 at STP are produced from 1.5 g KClO3

Answers

Answer:

64.2 L

i watch videos about this stuff because my grades were very low now im bringing the up

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.

The balanced chemical equation for this decomposition reaction looks like this

2KClO3(s]heat×−−−→2KCl(s]+3O2(g]↑⏐

The phase change between white tin and gray tin is difficult to observe directly. Both substances can be burned, however. From these equations, calculate AHⓇ for the conversion of gray tin into white tin:
Sn(s, white) + O2(g) + SnO2(g) AH = -580.69 kJ
Sn(s, gray) + O2(g) + SnO2(g) AH° = -582.78 kJ
AH = _________ kJ

Answers

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]

A system gains 687 kJ of heat, resulting in a change in internal energy of the system equal to 156 kJ. How much work is done?
1. Work was done by the system.2. Work was done on the system.

Answers

Answer:

w = -531 kJ

1. Work was done by the system.

Explanation:

Step 1: Given data

Heat gained by the system (q): 687 kJ (By convention, when the system absorbs heat, q > 0).Change in the internal energy of the system (ΔU°): 156 kJ

Step 2: Calculate the work done (w)

We will use the following expression.

ΔU° = q + w

w = ΔU° - q

w = 156 kJ - 687 kJ

w = -531 kJ

By convention, when w < 0, work is done by the system on the surroundings.

In an experiment, two unknown compounds (one an ether and the other an amine) of equal molecular mass were dissolved in water. The result of the experiment is shown in the table.


Solubility Comparison
Unknown Compound Solubility (g/100 ml water)
A 4
B 0.25


Which of the following correctly explains the identity of Compound A and its solubility?
It is an amine; it contains a nitrogen atom that will allow nitrogen-hydrogen bonds to form while in water.
It is an ether; because the oxygen atom is within the carbon chain, so it is free to form oxy-hydrogen bonds to make it more soluble.
It is an ether; the high polarity of the oxygen-hydrogen bond makes it more soluble.
It is an amine; because the lower electronegativity of N than H makes it more soluble.

Answers

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.

A current of 5.29 A is passed through a Sn(NO3)2 solution for 1.30 h . How much tin is plated out of the solution?

Answers

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.

How do we calculate mass?

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.
