the dependant variable is spilled water
the independent is the heat
na + cl ⇌ nacl
balanced chemical equation:
na + 2cl ⇌ nacl2
sodium + clorine goes to form sodium chloride (table salt).
the product is nacl2.
and the reactants are na and cl.
(note: if you don’t know what ⇌ means, read below: -
⇌(double head arrow) means reversible reaction).
answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
