When the formation of a substance is negative, it means that it releases heat to the surroundings. When
it releases heat to the surroundings, the reaction is exothermic. When it absorbs heat from the surroundings, the reaction is endothermic.
the spin quantum number has values+1212 of -1212 describes the trends in ionic size.
spin quantum is denoted by (s) as it represents the electronic configuration of the atom and the ionic size also depends on the electronic configuration of the sub-shells of the atom like l, m, n, s.
ionic size increases as the electronic configuration increases because the electron adds as we move up to a higher atomic number
all the other quantum numbers may vary from atom to atom but the spin quantum number remains either +1212 or -1212. it also describes the orientation of the electrons in an atom and the axis of electrons in an atom.

Answer:
the specific heat capacity of ethanol is 2.4608 J/g°C
The variation in the final temperature is due to the rate of heat lost. Calorimeters do not dissipate or absorb energy
Explanation:
the solution is in the attached Word file
Not only for plants, but also for every organism and every life form nitrogen is important because it poses as catalyst that supports different is chemical reactions of growth. N is filled with chlorophyll that actually gives you the answer on the question as chlorophyll allow plant to perform photosynthesis by absorbing energy from light that leads to the growth. So, it is important because it provides <span>photosynthesis.</span>
Im unsure :( maybe try looking up a calorie calculator
