Cyclobutane, c h , consisting of molecules in which 48 four carbon atoms form a ring, decomposes, when heated, to give ethylene. the reaction is first order. in an experiment, the initial con- centration of cyclobutane was 0.00150 m. after heating at 450°c for 455 s, this was reduced to 0.00119 m. what was the concentration of cyclobutane after a total of 875 s?

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.
