1.       Na reação de 22,2 g de Ca (OH)2 com HCl, segundo a equação:

Ca (OH)2   +    HCl     =    CaCl2    +    H2O

Calcular:

a)      A massa do ácido clorídrico que deve reagir;

b)       A massa do sal (CaCl2) formado;

c)       O número de moléculas de água formadas

 

2.       Utilizando 18,4 g de álcool (C2H6O) na reação de combustão:

C2H6O    +     O2    =    CO2     +     H2O

Calcular:

a)      O número de mols de O2 gastos;

b)      A massa de gás carbônico obtido;

c)       O número de moléculas de água obtidas

 

3.       Em uma amostra de 3 kg de calcário (CaCO3), calcule:

a)      O número de mols

b)      O número de moléculas

 

4.       Calcular a massa e o volume ocupado, nas CNTP, por 3,01. 10 24 moléculas de gás butano (C4H10).
