Answer:

0.15

Explanation:

Whenever we are asked to calculate the pH of a particular solution in Chemistry it means that we are to look for its degree of acidity or basicity of such solution. Since the question is about an acidic solution, that is HNO3 we are to find the degree of acidity in the solution.

Therefore, the formula for the pH of a solution is given below;

pH = - log [ H^+].

In the question, we are given the hydrogen ion concentration to be = 0.71 M.

Hence, pH = - log [0.71].

pH = 0.14874165128092471.

pH =0.15.

It means that the solution is very acidic.

Answer:

pH of HNO₃ having an hydrogen ion concentration of 0.71M is 0.149

Explanation:

HNO₃ (aqueous) ⇄ H⁺ + NO3⁻

The pH is defined as the negative log of the hydrogen ion concentration

pH = - log [H⁺]

From the question, the hydrogen ion concentration is given as 0.71M, therefore

pH = -log [0.71]

     = 0.149

69. The student's skin was obviously warmer than the initial temperature of the bracelet. According to the second law of thermodynamics, heat transfers from a higher temperature to a lower temperature hence heat transfers from the student's skin to the bracelet warming up the bracelet. 

70. moles of copper=mass of copper/molar mass of copper
=30.1g/(63.55g/mol)= 0.4736 moles Cu

71. Delta H( heat released) = mCp(deltaT) = 30.1g(0.385 J/gK)(33-19)K = 162.23J

72. Copper is chemically less active than iron.
