Answer:
The pH decreases very quickly, more quickly than earlier or later in the titration.
I think because SA-SB titration have the straight line where the equivalence point is where pH change is very steep and fast. Also pH is gonna decrease because after equivalence point you have more acid then base.
Explanation:
Answer: You meant in constant temperature?
Because temperature is not mentioned at the beginning.
I suppose temperature remains constant, otherwise
there is no enough data for solving the problem
Explanation: According Boyle´s law in constant temperature
pV = constant. So p1V1 = p2V2 and pressure p2 = p1V1 /V2
= 88 atm · 18 l / 12 l = 132 atm.
Answer:
The Lassaigne's test, also known as
the sodium fusion test, is used in
elemental analysis to determine the
presenceof foreign elements,
specifically halogens, nitrogen, and
sulfur, in an organic compound.

B. High temp = more thermal energy =more disorder as molecules move randomly = move from hot to colder substance(heat moves from hot to cold)
When its frozen it gets bigger, when it evaporates, it gets smaller. It has something to do with the atoms
