Consider this reaction taking place in a closed container: 2N2(g) + 3H2(g) → 2NH3(g)
If you wanted to increase the yield of ammonia, according to le Châtelier's principle, you could
A)
add a catalyst.
B)
increase the pressure.
C)
increase the size of the container.
D)
decrease the number of moles of nitrogen.

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.
