Calculate the respective masses of oxygen used up and SO2 produced if 50cm*3 of SO2 were produced at stp when some quantity of powered sulphur were completely burnt in excess oxygen.​

asking the goog might u get an answer

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.
