Sulphur is a non-metal because it is consistent with three physical properties listed for non-metals. It isa poor conductor of heat and electricity, because electrons are not free to move. Can sodium conduct electricity? Solid sodium is good conductors of electricityas in sodium there is no ba...
Three bromine-containing N-heterocycles, namely 9-(4-bromophenyl)-9H-carbazole, 3-bromo-9-phenyl-9H-carbazole, and 1-(5-bromoindolin-1-yl)ethan-1-one, were coupled with either dialkyl phosphite (e.g. (MeO)2P(O)H or (EtO)2P(O)H) or diarylphosphine oxide (e.g., Ph2P(O)H, ...
what is SO4 and why does it have a charge of -2? A small amount of liquid bromine is added to a container which is then sealed. Using the ideas of kinetic energy, can you explain why after one hour the bromine molecules have spread uniformly to occu ...
What chemical bond forms when given different atoms: (1) bromine and hydrogen and (2) ammonia and calcium fluoride? Explain how you arrived at the answers. Why are metals good conductors, both of heat and electricity? Why do hot molecules move faster than cold molecules? In co2 laser, the...
For a substance to conduct electricity, it needs charged particles that are free to flow when a voltage (potential difference) is applied. The charged particles are usually electrons, but free ions can also conduct electricity...
Two bromine atoms Why is the second law of thermodynamics important? What is kinetic energy? What is potential energy? Explain with examples. The entropy of formation of Mg2+ (aq) is -138.1 J/mol K. Explain why from a molecular level, why the entropy of formation...
