Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
<span>Chemical formula of ammonia = NH3
As we can see there are three atoms of hydrogen in one molecule of ammonia.
So in the 200 molecule of ammonia there will be = 200*3 = 600 atoms of hydrogen.
Answer - 600 atoms of hydrogen.</span>
The product Bismuth (III) sulfide (
) is used as a starting material for the synthesis of other bismuth compounds. It is formed, together with an acid, from a reaction between a Bismuth (III) salt and hydrogen sulfide (
). In the given reaction, the Bismuth salt used in the reaction is Bismuth (III) chloride (
).
The balanced reaction of
and
is
Thus, the coefficient of HCl in the reaction is 6.
The molar mass of nitrogen dioxide to the nearest gram-per-mole is 46 g/mol.
