A unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10-27<span> kg.</span>
Answer:
74 g/mol
Explanation:
Using a periodic table, we can determine the molar mass by adding together 1 Ca, 2 O, and 2 H. This turns out to be approximately (40+32+2) = 74 g/mol
Answer is: True.
Example for p<span>olyhydroxyl alcohol is glycerol.</span>
Glycerol (1,2,3-Propanetriol, glycerine<span> or glycerin) is a simple polyol (it has three hydroxyl group) compound with formula (OH-CH</span>₂-CH(OH)-CH₂OH or C₃H₈O₃).
The glycerine <span>backbone is found in
all lipids known as triglycerides. (ester derived from glycerol and three fatty acids).
Glycerol is soluble in water and it is hygroscopic.</span>
Yes, because nothing has changed. The same ingredients are used and if one reaction happened in a a bag then why wouldn’t it happen in a container?
Answer: The IUPAC name of
is 5-chloro-2-pentyne
Explanation:
1. First select the longest possible carbon chain. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
2. The longest possible carbon chain should contain all the bonds and functional groups.
3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.
4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.
Thus the IUPAC name of
is 5-chloro-2-pentyne
