A container of carbon dioxide has a volume of 240 cm3 at a temp. of 22 degrees c. If the pressure remains constant what is the volume at 44 degrees celsius

the answer to your question is c

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.
