What mass, in grams, of CO2 and H20 N
is formed from 2.55 mol of propane?

The mass of and produced are 336.6 g and 183.6 g respectively.

Explanation:

The combustion reaction between propane and oxygen leads to formation of carbon dioxide and water.

Law of Conservation of mass states that the mass will remain constant for a balanced equation. This is carried out when the total number of atoms on reactant side is same as the total number of atoms on the product side. Thus the equation must be balanced.

a) 1 mol of propane produces = 3 moles of

Thus 2.55 mol of propane produces =

mass of

b) 1 mol of propane produces = 4 moles of

Thus 2.55 mol of propane produces =

mass of

The mass of and produced are 336.6 g and 183.6 g respectively.

i do not get it   at all

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
