Phosphorus pentachloride decomposes at 160 °C to make phosphorus trichloride and chlorine gas. PCl5 (g) ⇌ PCl3 (g) + Cl2 (g) A 1.00 L vessel contains 4.50 M phosphorus pentachloride and 0.25 M phosphorus trichloride before heating to initiate decomposition. When the reaction reaches equilibrium, the concentration of chlorine gas is 3.20 M. The equilibrium expression in terms of concentration is Kc=[PCl3][Cl2][PCl5]. Which is the value of Kc under these conditions?

ill try to . no promises tho.

explanation:

thats how its supposed to be

it is a solid

explanation:

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.
