Em um laboratório de química realizou-se uma titulação de 50 mL de uma solução de soda caustica NaOH de concentração 6 mol/L, foi utilizada uma solução de ácido sulfúrico de concentração 2,5 mol/L, de acordo com a equação química a seguir.

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.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
