slega [8]3 years ago
4 0

Answer:

0.080 M

Explanation:

From the question given above, the following data were obtained:

Concentration of H₂SO₃ = 0.080 M

Concentration of SO₃²¯ =…?

The concentration of SO₃²¯, can be obtained as follow:

H₂SO₃ (aq) <==> 2H⁺ (aq) + SO₃²¯ (aq)

From the balanced equation for above,

1 mole of H₂SO₃ produced 1 mole of SO₃²¯.

Therefore, 0.080 M H₂SO₃ will also produce 0.080 M SO₃²¯.

Thus, the concentration of SO₃²¯ is 0.080 M

You have 16.0 g of some compound and you perform an experiment to remove all of the oxygen, 11.2 g of iron is left. What is the
oksian1 [2.3K]

The empirical formula of this compound is equal to Fe_{2}O_3.

<h3>Empirical formula</h3>

To calculate the empirical formula of a compound, it is necessary to know the number of moles present.

Therefore, we will use the molar mass of iron and oxygen to find the amount of moles, so that:

MM_O = 16g/mol\\MM_Fe = 55.8g/mol

                                        MM = \frac{m}{mol}

  • Oxygen

                                            16 = \frac{4.8}{mol}

                                            mol = 0.3

  • Iron

                                   

                                               55.8 = \frac{11.2}{mol}

                                               mol = 0.2

Finally, as the empirical formula is composed of integers numbers of moles, just multiply the values ​​by the smallest common factor to transform into an integer, so that:

                                       O =>  0.3 \times 10 = 3moles

                                       Fe => 0.2 \times 10 = 2moles

So, the empirical formula of this compound is equal to Fe_{2}O_3

A 25.0 ml solution of .0600 M EDTA was added to a 57.0 ml sample containing an unknown concentration of V3+. All V3+ present for
Rom4ik [11]

Explanation:

Let us assume that the ratio for the given reaction is 1:1.

Therefore, we will calculate the moles of Ga^{3+} as follows.

   Moles of Ga^{3+} solution = molarity × volume (L)

                              = 0.0440 M × 0.014 L

                              = 0.000616 moles

Moles of excess EDTA = 0.000616 moles

Also, the initial moles of EDTA will be calculated as follows.

     Total initial moles of EDTA = 0.0600 M × 0.025 L

                                                 = 0.0015

Therefore, moles of EDTA reacted with V^{3+} will be as follows.

                = 0.0015 - 0.000616

                = 0.00088 moles

Since, we have supposed a 1 : 1 ratio between V^{3+} and EDTA .

So, moles of V^{3+} = 0.00088 moles

Now, we will calculate the molarity of V^{3+} as follows.

       Molarity of V^{3+} solution = \frac{\text{moles}}{\text{volume (L)}}

                             = \frac{0.00088 moles}{0.057 L}

                             = 0.015 M

Thus, we can conclude that the original concentration of the V^{3+} solution is 0.015 M.

When the temperature of the gas changes from cold to hot, the amount of pressure is ___________.
Klio2033 [76]
The pressure would increase. When the temperature change form cold to hot, the gas will find ways to escape from containment. Thus, if it cannot escape that pressure will keep on increasing as the temperature rises.
