Pyrotechnic compositions emit light by three basic processes - incandescence (blackbody radiation) atomic emission, and molecular emission.
Water is a very good solvent due to its very polar nature. A polar substance is one where the atoms within the molecules of the substance carry partial charges. Oxygen is very electronegative, so it induces partial charges within the bonds of the water molecule. The extremely polar nature of water, along with its ability to make hydrogen bonds, ensure that it is able to dissolve a variety of substances.
Answer:
97.994 g/mol
Explanation:
One molecule of H₃PO₄ contains three atoms of H, one of P, and four of O.
3H = 3 × 1.0079 u = 3.0237 u
1P = 1 × 30.974 u = 30.974 u
4O = 4 × 15.999 u = <u>63.996 u
</u>
Total = 97.994 u
One molecule has a mass of 97.994 u.
One mole has a mass of 97.994 g.
The molar mass of H₃PO₄ is 97.994 g/mol.
Answer:
A) Electrons
A) 16-8=8 so it'd be 8
(Relative atomic mass - atomic number = neutrons)
A) 12
Same thing as last one.
31-15=16 ( did you type the wrong options if not then huh?)
Explanation:
The answer it the function
