solution:
A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
Starting by hitting acetylene with NaNH2 to deprotonate, this C-- will attack the C connected to the Br Sn2 style to lengthen the chain by two carbons.
Do this same thing again with the other CH of the acetylene and another bromoethaneto get a six carbon chain, namely, 3-hexyne.
Now, reduce the alkyne to an alkene via H2/Pd/C, and that gives 3-hexene.
Answer: There is 125 mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution
Explanation:
Given: = 2.0 M, = ?
= 0.5 M, = 500 mL
Formula used to calculate the volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there is 125 mL of a 2.0 M solution are needed to make 500 mL of a 0.5 M solution.
Answer:
Explanation:
Atoms generally tend to achieve there octet configuration (i.e have there outermost shell completely filled) and become stable. They do this by participating in chemical bonding (majorly by transferring or sharing electrons). Atoms (of elements) that have very few electrons on there outermost shell (like the group 1 atoms; example is sodium) and atoms that have almost completely filled outermost shell (like the group 7 elements; example is fluorine) are highly reactive because it is easier to lose an electron to become stable and also easier to gain an electron to become stable. However, elements in group zero of the periodic table do not participate in bonding and resist chemical reactions because they have a completely filled outermost shell and are hence stable.
Since, the groups of the periodic table shows the number of electrons in the outermost shell of each member (of a particular group), the chemical properties of each group is usually almost similar.
