What is the concentration of nitrate ions in a solution obtained by mixing 300. Ml of 0. 210 m potassium nitrate(aq) with 300. Ml of 0. 150 m zinc nitrate(aq).

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

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.
