Upon decomposition, one sample of magnesium fluoride produced 1.65 kg of magnesium and 2.56 kg of fluorine. a second sample produced 1.32 kg of magnesium. part a how much fluorine (in grams) did the second sample produce?

Answer : The mass of fluorine in second sample produces, 2.048 grams

Law of definite proportion states that in a chemical compound, the components of the element are in fixed ratio.

The given chemical compound is magnesium fluoride. In the magnesium fluoride the components of the element magnesium and fluorine are in fixed ratio that is, 1 : 1

= mass of magnesium in sample 1 = 1.65 g

= mass of fluorine in sample 1 = 2.56 g

= mass of magnesium in sample 2 = 1.32 g

= mass of fluorine in sample 2 = x

Now put all the give values in the above relation, we get

Therefore, the mass of fluorine in second sample produces, 2.048 grams

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
