Answer:
203 grams
Explanation:
The no. of moles of (6.3 x 10²⁴ molecules--Avagadros number) of NH₃ = (1.0 mol)(7.2 x 10²⁴ molecules)/(6.022 x 10²³ molecules) = 11.96 mol.
The no. of grams of NH₃ present = no. of moles x molar mass = (11.96 mol)(17.0 g/mol) = 203.3 g ≅ 203.0 g.
Answer:
the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
H^+ = acid
OH^- = alkaline
Acids have a pH of below 7. The lower the number, the strongest the acid.
The reactions produces an enormous amount of energy per unit mass compared to nuclear fission. Hope this helped
Answer. Dolphin reproduction starts when a couple of dolphins mate. The copulation occurs belly to belly initiating the gestation period which varies according to the species but ranges from 11 to 17 months in the case of the killer whale, being 12 months for the common bottlenose dolphin.
