How many mL of 0.2860 M sulfuric acid are required to react with 58.42 mL of 0.09756 M iron(III) hydroxide

Answers

Answer 1

Answer:

0.05978 mL of 0.2860 M sulfuric acid is required to react with 58.42 mL of 0.09756 M iron (III) hydroxide.

Explanation:

The balanced reaction between tha surfuric acid and iron (III) hydroxide is:

Fe(OH)₃ + 3 H₂SO₄ → Fe(HSO₄)₃ + 3 H₂O

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reactants and products participate in the reaction:

Fe(OH)₃: 1 mole H₂SO₄: 3 molesFe(HSO₄)₃: 1 mole H₂O: 3 moles

Being molarity (M) the number of moles of solute that are dissolved in a given volume:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

then the number of moles can be calculated as:

number of moles= molarity* volume

So, if 58.42 mL ( 0.05842 L) of 0.09756 M iron (III) hydroxide react, then it means that the number of moles that react are:

number of moles= 0.09756 M* 0.05842 L

number of moles= 0.005699 moles

Now it is possible to apply the following rule of three: if by stoichiometry 1 mole of Fe(OH) ₃ reacts with 3 moles of H₂SO₄, then 0.005699 moles of Fe(OH) ₃ with how many moles of H₂SO₄ does it react?

[tex]moles of H_{2} SO_{4} =\frac{0.005699 moles ofFe(OH)_{3}* 3moles of H_{2} SO_{4} }{1mole ofFe(OH)_{3}}[/tex]

moles of H₂SO₄= 0.017097

Being sulfuric acid 0.2860 M, it is replaced in the definition of molarity:

[tex]0.2860M=\frac{0.017097 moles}{volume}[/tex]

Solving for the volume:

[tex]volume=\frac{0.017097 moles}{0.2860 M}[/tex]

volume= 0.05978 mL

0.05978 mL of 0.2860 M sulfuric acid is required to react with 58.42 mL of 0.09756 M iron (III) hydroxide.

After burning your candle for a few hours you and your friend notice that it's mass has decreased. Your friend claims that the mass "disappeared". Why do you know he is wrong (Hint: it's a Scientific Law)? What actually happened to the mass? What form is that mass in now? What is this process called?

Answers

Answer:

The law of conversion of mass is a scientific law that says that mass or matter can not be created or destroyed like energy but changes its form in a different type of state. So, by the law of conversion of mass, you can say that mass is not disappeared but change in different forms of states of matter like gas, soot, or melted residues of candle and ash of thread.

Due to this, the mass of the solid or waxy state due to burning changes to gas released by burning and residue of wax that will be equal to the mass of the original mass.
