Answer is: temperature
and absolute brightness.
The Hertzsprung–Russell diagram shows the relationship between the star's absolute luminosities (the total amount of energy emitted per unit of time by a star) versus their effective temperatures (the temperature of a black body that would emit the same total amount of electromagnetic radiation).
The Hertzsprung–Russell diagram puts each star on a graph according the star's brightness against its temperature.
Answer:
energy is used to break bonds in reactants and energy is released when new bonds form in products.The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy there is no overall change in the amount of energy during the reaction.

Sorry if im wrong
Answer:The hybridisation of C1 and C2 are sp3 and sp2 respectively.
Explanation:
Here the first carbon (C-1) formed four straight single bonds.
Linking to the electron theory (a fig.1 shown below) one electron from 2s orbital moves to the empty 2pz orbital.
The 2s and the three 2p orbitals hybridise and each orbital will be completed by one electron shared mutually with and from N, H, H, and the other C.
C-2 the second carbon has an sp2 because it forms a double bond with oxygen.
In the sp2 hybridisation the 2s orbital hybridises with only two 2p orbitals leaving the other 2p orbital unhybridised. The orbitals in sp2 is to be completed with one more electron each by sharing covalently with the C, O and the other O.
Note: The unhybridised p orbital is completed with the other shared electron of the oxygen. This forms the π bond in the carbon-oxygen double bond. (Fig 2. Shows the electronic arrangements.)
Titanium(III) oxide is a titanium oxide with formula Ti2O3.
The answer would be Ca + FeN = Ca3N2 + 2Fe
