A student carries out this chemical reaction in a beaker:
nydimaria [60]

Answer:The correct answer is option (C).

Explanation:

Zn+CuCl_2\rightarrow Cu+ZnCl_2

After the reaction between Zinc and copper(II) chloride, Zinc chloride and copper will be obtained as a product. This reaction occurs because zinc is more reactive than copper which displaces the copper from its aqueous solution.

The student will expect to find copper metal at bottom of the beaker with aqueous solution of zinc chloride.

Hence the correct answer is option (C).

Show dipole dipole force of water and ethyll alcohol.​
Alexeev081 [22]

Answer:

Water: H2O --> [H+] + [OH-]

Ethyl alcohol: C2H5OH --> [C2H5O-] + [H+]

Explanation:

Dipole-dipole force is observed when an ionic compound ionizes (forms ions), revealing its slightly positive ion and slightly negatively ion.

The chemical formula of Water is H2O.

H2O --> [H+] + [OH-]

The chemical formula of ethyl alcohol is C2H5OH.

C2H5OH --> [C2H5O-] + [H+]

Note the positive and negative parts of both water and ethyl alcohol as expressed in the equations above.

What mass in grams of SO2 is needed to react with 37.50 mol of Oz?
-BARSIC- [3]

Answer:

4804.5 g of SO₂ are needed to the reaction

Explanation:

The reaction to produce sulfuric acid is:

2SO₂ + O₂ + 2H₂O →  2H₂SO₄

Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.

If 1 mol of O₂ react to 2 moles of SO₂

Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂

We convert the moles to mass, to know the answer:

75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂
