Atomic mass Boron ( B ) = 10.811 u.m.a
10.811 g -------------- 6.02x10²³ atoms
5.40 g ----------------- ?? atoms
5.40 x ( 6.02x10²³) / 10.811 =
3.0069x10²³ atoms
Answer:
B
Explanation:
In order for any conduction to take place it needs to go through a solid. Therefore it cannot travel through empty space
Answer:
<span>Primary alcohols oxidize to form Carboxylic Acids.
Explanation:
Primary Alcohols when treated with Oxidizing agents like </span>K₂Cr₂O₇ and CrO₃<span> produces carboxylic Acids as a final product. This oxidation to Carboxylic Acid first passes through Aldehydes and then is oxidized to carboxylic Acid.
</span> As K₂Cr₂O₇ and CrO₃ are strong oxidizing agents, if a mild oxidizing agent like <span>Pyridinium Chlorochromate (PCC) is used then primary Alcohol will convert into Aldehyde.</span>
So, on reacting with strong oxidizing agent primary alcohol will produce carboxylic acids via aldehydes and when treated with mild oxidizing agent primary alcohol will produce aldehyde.
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.
