Since the molar heat capacity of a substance is the specific heat c times the molar mass of the substance M/N its numerical value is generally smaller than that of the specific heat. Paraffin wax , for example, has a specific heat of about 2500 J⋅K −1 ⋅kg −1 but a molar heat capacity of about 600 J⋅K −1 ⋅mol −1 .
Dinitrogen dioxide is an inorganic compound having molecular formula N 2 O 2.Many structural isomers are possible. The covalent bonding pattern O=N–N=O (a non-cyclic dimer of nitric oxide (NO)) is predicted to be the most stable isomer based on ab initio calculations and is the only one that has been experimentally produced.

Child care facilities in the US have the option of becoming accredited. An outside organization is in charge of setting and enforcing this standard. In centers, National Association for the Education of Young Children institutes it. [58] For family child care providers, the National Association of Family Child Care Providers award the ...

At room temperature, dicyanoacetylene is a clear liquid. Because of its high endothermic heat of formation , it can explode to carbon powder and nitrogen gas, and it burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), the hottest flame in oxygen; burned in ozone at high pressure the flame ...
Ni(H 2 O) 2+ 6 + 2 NO − 2 ⇌ Ni(NO 2) 2 (H 2 O) 4 + 2 H 2 O; K = 0.16 at standard conditions The complex is a much more intense emerald green colour than the Ni(H 2 O) 6 2+ ion. Brooker claims that intense light photocatalyses the destruction of the ionic nitro complexes, leaving only Ni(NO 2 ) 2 (H 2 O) 4 .
The most common polymorph is γ, but β form can also be produced in an applied magnetic field (ca. 1 Tesla) [8] or by phase transition from γ decreasing the temperature below 158 K. [14] The structure containing two C-H groups on one benzene ring, so-called DUO, was analyzed by infrared spectroscopy. [15]
