Every Methane molecule looks different. True or false?
Akimi4 [234]

Answer:

False

Explanation:

Molecules of the same substance are made up of the same type of atoms and look exactly alike.

Hence, if I have two molecules of methane having exactly the same atoms of carbon and hydrogen,the both are indistinguishable from each other based on appearance.

Hence all molecules of methane are exactly alike if they are composed of atoms of the same isotope of hydrogen and carbon.

How many grams of AlCl3 can be prepared from 3.5 moles of HCl gas?
poizon [28]

Answer:

156 g of AlCl₃ will be produced from 3.5 moles of HCl.

Explanation:

Given data:

Number of moles of HCl = 3.5 mol

Grams of AlCl₃ produced = ?

Solution:

Balanced Chemical equation:

3HCl + Al(OH)₃   →  AlCl₃ + 3H₂O

Now we will compare the moles of AlCl₃  with HCl from balanced chemical equation.

                   HCl          :           AlCl₃

                     3            :              1

                   3.5           :           1/3×3.5 = 1.17 mol

Mass of  AlCl₃ produced:

Mass = number of moles ×molar mass

Mass = 1.17 mol ×   133.341 g/mol

Mass =  156 g

Thus 156 g of AlCl₃ will be produced from 3.5 moles of HCl.
