Chlorofluorocarbons such as CCl2F and CCI,F, have been linked to ozone depletion in Antarctica. In 1994, these gases were found

Ilya [14]

Answer:

a) molarity of CCl3F = 1.12 × 10^-11 mol/dm³

Molarity of CCl2F2 = 2.20 × 10^-11 mol/dm³

B) molarity of CCL3F = 7.96 × 10 ^-13 mol/dm³

Molarity of CCl2F2 = 1.55 × 10^-12 mol/dm³

Explanation:

Using the ideal gas equation:

PV = nRT

If you had excess chlorine, how many moles of of aluminum chloride could be produced from 10.0 gg of aluminum? Express your answ

gayaneshka [121]

Answer:

The answer is 0.370moles (3 s.f)

Explanation:

Step 1: write the balanced equation for the reaction

Equation for the reaction:

2Al(s) + 6HCl(g) ---------> 2AlCl3(g) + 3H2(g)

Step 2: Equate the mole of the needed substances

So therefore,

2moles of aluminum will produce 2 moles of aluminum chloride

Note that:

Relative atomic mass of Al = 27 g/mole

And, 27g of Al = 1 mole of Al.

Step 3: Solve for the required number of mole.

2moles of Al = 2moles of AlCl3

Same as

1 mole of Al = 1 mole of AlCl3

27g of Al = 1 mole of AlCl3

10g of Al = (1/27 * 10g) of AlCl3

10g of Al = 0.370moles of AlCl3

Thanks

A biochemist who is studying the properties of certain sulfur (s)-containing compounds in the body, wonders whether trace amount

Leni [432]

Elements of the same group show similar chemical properties as they have the same number of valence electrons. Sulfur belongs to the group 16 or 6 A or the oxygen family with 6 valence electrons. The elements of group 6 A are Oxygen, Sulfur, Selenium, Tellurium and Polonium. All of these elements show similar chemical properties. Therefore, when a biochemist studying the properties a sulfur containing biochemical compounds in the body wants to look at any other non-metal with similar properties, he has to consider other elements of the group 6 A like Oxygen (O), Selenium (Se), Tellurium (Te) and Polonium (Po).
