Consider the following reaction: Cl2 + Na2S → 2NaCl + S
The percent yield of sulfur when 71.0 g of Cl2 is reacted in
excess Na2S solution is 73.0 %.
What is the actual mass of sulfur yielded by this reaction?
(Molar mass of S = 32.1 g/mol, molar mass of Cl2 = 71.0 g/mol)

Indicate whether the specified alkyl halides will form primarily substitution products, only elimination products, both substitution and elimination products, or no products when they react with sodium methoxide. 1-bromobutane 1-bromo-2-methylpropane 2-bromobutane 2-bromo-2-methylpropane

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
