No Japão, um movimento nacional para a promoção da luta contra o aquecimento global leva o slogan: uma pessoa, produz aproximadamente por dia 2,5 kg de Contaminantes! Essa é uma condição que não envolve somente a respiração humana que produz CO2, mas também a produção de lixo.

Uma Idéia poderia ser a queima completa desse lixo, baseado nessa ideia vamos analisar qual a quantidade de oxigenio é necessario em moles para consumir esses Contaminantes:

REÇÃO QUÍMICA ==> CONTAMINANTE + O2 --> QUEIMA COMPLETA

MM O2 = 32 g/mol

MM contaminante= 250 g/mol

Para saber o balanceamento dessa reação é só usar o primeiro número primo par como número de moles do contaminante e em seguida elevá-lo ao cubo para obter o numero de moles de O2.

DICA DO MESTRE= 1Kg = 1000g

a) 50 moles
b) 40 moles
c) 30 moles
d) 20 moles
e) 10 moles

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
