The statement about "Carbon can bond with other carbon atoms to produce cyclic hydrocarbon structures" is true. <span>Carbon
can also bond with other four atoms because of its outer shell (valence shell)
that has four electrons. This is the reason why organic molecules can be so
large because of this bonding. </span>
CO2 is carbon dioxide which is most famous for being in gas form so i would figure if it was exposed to freezing temperatures it would turn into a liquid then maybe a solid<span />
Answer:
Stanley Miller and Harold Urey
Explanation:
Experiments in which electricity was discharged into a vessel containing hydrogen gas, water vapor, methane, and ammonia were conducted by Miller and Urey.
Biochemists Stanley Miller and Harold Urey conducted an experiment in the 1950s which revealed many organic compounds can be spontaneously formed by simulating the early atmosphere conditions of Earth.
Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite).
