Given
Pictures for atom, anion, and cation
Required
Classification
Solution
Represent atom : Picture B
Number of protons = number of electrons = 6 = neutral atom
Represent cation : Picture C
Number of protons > number of electrons = 6>5 : charge +1(positive charge)
Represent anionn : Picture A
Number of protons < number of electrons = 5<6 : charge -19negative charge)
29.26 gram
Explanation:
No of molecules = no of mole × Avogadro's number
No of molecules = mass in gram/ molar mass × Avogadros number
Mass in gram =No of molecules×molar mass / Avogadros number
Mass in gram = 3.012 ×10^23 × 58.5/6.02×10^23
29.26 gram
Alchemists advanced the tools and procedures for working with chemicals. Alchemists also developed methods for sorting out mixtures and cleansing chemicals. They designed equipment that is still in use today including beakers, flasks, tongs, funnels, and the mortar and pestle. Also, Alchemists backed to an unbelievable variety of what would later be acquainted as chemical industries: basic metallurgy, metalworking, the invention of inks, dyes, paints, and cosmetics, leather-tanning, and the preparation of extracts and liquors.
