A. pH meter is the instrument which will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.
Litmus paper is just a paper which changes color based on whether the solution is an acid or a base. Phenolphthalein is an indicator which changes color based on pH values. And bromthymol blue doesn't tell concentrations, it is just a pH indicator for weak acids and bases.
Answer:
See explanation
Explanation:
i) Oxidation half-reaction:
2Ag(s) ----> 2Ag^+(aq) + 2e
Reduction half-reaction:
Ni^2+(aq) + 2e ----> Ni(s)
ii) Ag is the anode while Ni is the cathode
iii) E°cell = E°cathode - E°anode
E°cell = (-0.25) - (0.80)
E°cell = -1.05 V
iv) This is an electrolytic cell since the cell reaction is non spontaneous.
The answer is 59.01 g
If a 100-gram sample of NaCl consists of 39.34 g of sodium, a 150-gram sample of NaCl will consist x g of sodium:
100 g : 39.34 g = 150 g : x
x = 39.34 g * 150 g : 100 g
x = 59.01 g
The splitting of an atom is known as nuclear fission, in which a high-energy particle is introduced to a heavy atom to instigate the separation; heavy atoms are known to be naturally unstable due to their size, and a small catalyst is enough to tip the system in favor of splitting. The act of fission usually produces two daughter nuclei and some byproduct, such as an alpha or beta particle, etc.
