What is the mole ratio between ammonium sulfate (NH4)2SO4 and ammonia (NH3) ?

the mole ratio of ammonium sulfate to ammonia is 1:2. Hence, our sample of 30.0 moles of ammonia will produce:

of ammonium sulfate.

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.
