...by heating with a Bunsen burner? In each case, explain your answer.

Ethyl alcohol (bold) in whiskey

CuSO4.4H2O/HgO (bold)

KClO3/CaCO3 (bold)

Hints:
1. Water of hydration (as in CuSO4.4H2O) can be driven out by strong heating.
2. When HgO is heated, it decomposes to Hg(l) and O2(g).
3. Carbonates (as in CaCO3) decompose upon heating yielding a metal oxide plus CO2(g).

Just for clarification, the target compounds in bold are ethyl alcohol, HgO, and CaCO3. For ethyl alcohol, maybe you could just use its empirical formula C2H6O.

Mathematician states “Newton and Leibniz developed the calculus…. Their ideas were attacked for being full of paradoxes.” Newton’s formulation of calculus was self-contradictory yet it worked. Newton worked with small increments going of to a zero limit. Berkeley showed that this leads to logical inconsistency. The main problem Bunch notes was “that a quantity was very close to zero, but not zero, during the first part of the operation then it became zero at the end.

it is no use just saying oh yes so what mathematics makes my pc work so i can post this msg The point is logically calculus is llogical and by the standard of logic can not be true if it is in self-contradiction. Therefore how it works becomes a complete mystery seing by the accepted standard of truth ie logic it is not true. This is one one reason why this author says mathematics is mreaningless

So that, the Universe keeps the balance of its existence, was necessary to interact a source of nêutrons, it enters two power plants you oppose. Example: The Sun answers as the nucleus (positive energies, concentrated - “heat”). The set of all the stars amongst the interstellar System, answers for the peripheral part (negative energies, distributed - “Cold”). The Land in turn answers through its orbit “center of the balanced energies” (nêutrons - heat and cold) answering for this conscience of the life of the species beyond receiving and liberating energies finitely to feed the Sun and the Interstellar System.
