The HCl is a strong acid, that is, it is fully consumed <span>in the reaction.

HCl(aq) ------------> H</span>₃O⁺(aq)   + Cl⁻(aq)
 ↓                                ↓               ↓
10⁻⁴ M                      0                    0
-10⁻⁴                  +10⁻⁴              +10⁻⁴
_____________________________________
0                        + 10⁻⁴  M      <span> + 10⁻⁴  M

PH = - log [ H</span>₃O⁺ ]

PH = - log [ <span>10⁻⁴]

<span>PH =  4.0</span></span>

calculate the enthalpy change for converting 1.00 mol of liquid water at 100 C to water vapor at 145 degree celsius for water Δ
Svetllana [295]

Answer:

q1 = mCpΔT

    = 18.016g × 1.84J/g.K × (418.15-373.15)

     = 1491.72 J

q2 = n×ΔH vap

     =  1mol ×44.0kJ/mol

     = 44KJ

∴ qtotal = q1+ q2

             = 1.498kJ + 44.0kJ

             = 45.498KJ

Explanation: The heat flow can be separated into steps.all that is being observed at a constant pressure,the heat flow is equal to the enthalpy.

Which process is most likely responsible for the removal of the missing parts of the rock layers
Sav [38]
I believe Erosion is the process most likely responsible for the removal of the missing parts of the rock layers. Erosion involves the physical action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, then  moved away to another location.
