You have to find the stoichiometric ratio between AlCl₃ and BaCl₂. The common element between them is Cl. So, the ratio of Cl in BaCl₂ to AlCl₃ is 2/3. The molar mass of AlCl₃ is 133.34 g/mol. The solution is as follows:
Mass of AlCl₃ = (6 mol BaCl₂)(2 mol Cl/1 mol BaCl₂)(1 mol AlCl₃/3 mol Cl)(133.34 g/mol) = 533.36 g AlCl₃
The energy absorbed may be calculated using:
Q = mcΔT
Where Q is the energy absorbed, m is the mass of water, c is the specific heat capacity of the water and ΔT is the change is the temperature of the water. Substituting the values,
Q = (435)(4.18)(100-25)
Q = 136,372 J
The energy absorbed is 136.4 kJ
Carbon monoxide is produced in an engine
when incomplete combustion happened. In a combustion engine intake valve, it
combines the fuel and air (nitrogen and oxygen) and when spark plug ignites it
pushes the piston downwards. After that piston will push itself upward and
pushes the air that was generated by the combination of those components in the
exhaust valve. This is a repeated cycle which keeps the engine running. In a
perfect combustion process the air being released are carbon dioxide, water and
nitrogen. But when an incorrect ratio of the combination of fuel and air in the
engine is processed, carbon monoxide is being generated.
