(BONUS QUESTION) In the copper complexes investigated, the water and ammonia molecules act as Lewis bases (electron pair donors); they provide both of the electrons that form the covalent bonds between the Cu2+ ion and each ligand. Which ligand (H2O or NH3) is the stronger Lewis base? Explain your answer in terms of your answers for questions 3a and 3b. (hint: the poorer an oxidizing agent a species is, the harder it it to reduce that species. Hint #2: the copper complexes are reduced by gaining an electron.)

Answer and explanation:

Water and ammonia molecules acts as Lewis bases. its is clear from the spectrochemical series that NH₃ has stronger field ligand than water

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

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.
