How many liters of 4.0 M NaOH solution will react with 1.2 mol H2SO4? (Remember to balance the equation.)

H2SO4 + NaOH → Na2SO4 + H2O

A. 1.6 L
B. 1.2 L
C. 0.90 L
D. 0.60 L

Answers

Answer 1

Answer:

The answer is D. 0.60 L

Explanation:

The balanced reaction equation including states of matter is;

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)

More simple:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

Now, we can see from this reaction equation that the mole ratio of NaOH to H2SO4 is 2:1

Number of moles of H2SO4 reacted = 1.2 moles

Hence;

2 moles of NaOH reacts with 1 mole of H2SO4

x moles of NaOH reacts with 1.2 moles of H2SO4

x = 2 * 1.2/1 = 2.4 moles of NaOH

Recall that;

Number of moles = Concentration * Volume

Volume = number of moles/concentration

Volume of NaOH  is obtained from;

Volume = 2.4 moles/ 4.0 M

Volume =  0.60 L

Answer 2
The answer to this is D

Which property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it?

A. Manganese dioxide is an acid.
B. Manganese dioxide is a catalyst.
C. Manganese dioxide is highly reactive.
D. Manganese dioxide is used up very fast.

Answers

Answer:

B is the correct answer.

......Hopefully it it helpful.......

The property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it is Manganese dioxide is a catalyst.

Hence, option B is correct answer.

What is Catalyst in a chemical reaction ?

A catalyst in a chemical reaction is substance that increases the rate of a chemical reaction.

The reaction of manganese dioxide with hydrogen peroxide is

MnO₂ + H₂O₂ → H₂O + O₂

Now, lets check all options one by one.

Option (A): Manganese dioxide is an acid.

Manganese dioxide (MnO₂) is weak acid and its solubility is very less.

So, it is incorrect option.        

Option (B): Manganese dioxide is a catalyst.

Adding a catalyst to a reaction it speeds up the rate of reaction and in the absence of catalyst the reaction proceed slowly.  

So, it is correct option.

Option (C): Manganese dioxide is highly reactive.

Manganese dioxide is unstable. Manganese dioxide is is an inorganic compound. Manganese dioxide is oxidizing agent.

So, it is incorrect option.

Option (D): Manganese dioxide is used up very fast.

Manganese dioxide acts as catalyst for decomposition of H₂O₂ that means it is not consumed in the chemical reaction.

So, it is incorrect option.

Thus, from the above conclusion we can say that Manganese dioxide is a catalyst is the property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it.

Hence, option B is correct answer.
