Answer:
The wood is oak.
Explanation:
Given data:
Mass of wood = 70 g
Volume of wood = 103 cm³
Wood is oak = ?
Solution:
We will calculate the density of wood then we will compare it with literature value.
Density = mass/ volume
d = 70 g/ 103 cm³
d = 0.68 g/cm³
The density of oak is 0.59 - 0.90 g/cm³.
So its true, wood is oak.
A , i think because pure water won't dissolve the powder fast.
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.
Remember the acronym "Oil Rig". Oxidation is loss, Reduction is gain of electrons. Calcium is losing electrons so it's an oxidation reaction.
