Asample of gas occupies 9.0 ml at a pressure of 500.0 mm hg. a new volume of the same sample is at a pressure of 750.0 mm hg.

is the new pressure smaller or larger than the original?

therefore, is the new volume larger or smaller than 9.0 ml?

what is this new volume?

i don,t know so just answer mine

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.
