Answer:
Lewis structures, also known as Lewis dot diagrams, Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds
Explanation:
Copper is a good conductor
Answer:
I think that the statement is relative to speed because it is saying km per second.
The balanced reaction that describes the reaction between hydrogen and chlorine to produce hydrogen chloride is expressed H2 + Cl2 = 2HCl. Hence for every mole hydrogen chloride produced, there is 1 mole of hydrogen and chlorine needed. When 1 mole each of the reactants are used, there is 72.9 grams of HCl produced. We multiply 2 with the molar mass of HCl.
