Heterogeneous
The mixture has more than one phase of matter in it.
Answer:
The enthalpy change of the reaction is -66.88 kJ/mol.
Explanation:
Mass of the solution = m = 100 g
Heat capacity of the solution = c = 4.18 J/g°C
Initial temperature of the solutions before mixing = 
Final temperature of the solution after mixing = 
Heat gained by the solution due to heat released by reaction between HCl and silver nitrate = Q


Heat released due to reaction = Q' =-Q = -334.4 J
Moles of silver nitrate = n
Molarity of silver nitrate solution = 0.100 M
Volume of the silver nitrate solution = 50.0 mL = 0.050 L ( 1 mL = 0.001 L)


Enthalpy change of the reaction = 

1 J = 0.001 kJ
The enthalpy change of the reaction is -66.88 kJ/mol.
Answer:
If you spill an acid or base on your shoulder immediately wash well with water. Strong bases react with the oils in your shoulder to produce a soapy feeling layer. Rinse until well after that feeling is gone. Do not attempt to neutralize a spill on your skin.
