The following reaction was carried out in a 4.00 L reaction vessel at 1100 K : C(s)+H2O(g)⇌CO(g)+H2(g)

If during the course of the reaction, the vessel is found to contain 8.00 mol of C , 15.4 mol of H2O , 3.10 mol of CO , and 8.70 mol of H2 , what is the reaction quotient Q ?

they are made of gases.

they have a spherical shape.

they make energy through fusion.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

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.
