Answer:
Explanation:
The effect of azeotrope system is that , a positive azeotrope system boils at lower temperature than the other liquid constituents. It is also refer to as minimum temperature.
A negative azeotrope system boils at high temperature than other liquid constituents.
A azeotrope mixure refer to mixture of liquid with constant boiling point.
Answer:
Ka3 for the triprotic acid is 7.69*10^-11
Explanation:
Step 1: Data given
Ka1 = 0.0053
Ka2 = 1.5 * 10^-7
pH at the second equivalence point = 8.469
Step 2: Calculate Ka3
pKa = -log (Ka2) = 6.824
The pH at the second equivalence point (8.469) will be the average of pKa2 and pKa3. So,
8.469 = (6.824 + pKa3) / 2
pKa3 = 10.114
Ka3 = 10^-10.114 = 7.69*10^-11
Ka3 for the triprotic acid is 7.69*10^-11
According to Arrhenius definition of acids,
is an acid.
According to Arrhenius definition of acids and bases, acid is any substance that produces hydrogen ion in solution as its only positive ion.
Following this definition, let us now consider what happens when
is introduced into a water;
(aq)-------> NH3(aq) +
(aq)
Hence, according to Arrhenius definition of acids,
is an acid.

Answer: A
Explanation:
A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far. 79 is its charge (atomic number), which is both its proton number and electron number
