6.) the correct answer is endocytosis
Answer: Heat of reaction ∆H = -13.43kJ
Explanation:
The number of moles of NaOH = the number of moles of HCL = N
N = concentration × volume= CV = 0.5M × 500mL/1000ml/L
N= 0.5 × 0.5= 0.25mol
Since the Molar enthalpy is given by Hm = -53.72kJ/mol
Heat of reaction ∆H = N×Hm
∆H= 0.25mol × -53.72kJ/mol = -13.43kJ
Heat of reaction ∆H = -13.43kJ
Answer:
Saturated Solution. A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom. Unsaturated Solution. A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances. Supersaturated Solution.
