The following label was found on a bottle of liquid hydrocarbons in the laboratory of Dr. Ima Turkey following his disappearance

under mysterious circumstances. Although the name defines a structure unambiguously, it is not the correct IUPAC substitutive name. Give the correct name for the compound. Details count; pay attention to hyphens, commas, and spelling.
2-ethyl-2,4,6-trimethylheptane

If you draw the given compound you would see that the longest chain have 8 carbons, so the compound is octone not heptane.

Now you give indices for each carbon atom involved in the principal carbon chain in such a way the substituents are heaving the lowest number.

The correct name of the compound is:

2,4,6,6-tetramethyl-octane

In the attached figure you may see the drawing of the molecule.

Which statement explains why catalysts are important for living
Marina86 [1]

Answer:

Catalysts allow chemical reactions to occur at temperatures at which the organism lives.

Explanation:

Catalysts are molecules that speeden the rate of chemical reaction by lowering the activation energy of the reaction. In a living system, the catalyst are ENZYMES, which help to hasten up many biochemical reactions.

Another function of catalyst in living systems is that it allows chemical reactions to occur at temperatures at which the organism lives.

Are the bases on the interior or the exterior of the double helix? Are they randomly arranged or neatly stacked?
Lemur [1.5K]

the double helix is hydrogen bonded through the bases only so the bases are inside the helix only

as adenine combines with thymine and guanine with cytosine

phosphate are in the exterior of it

sugar groups constitute the double helix.

The mineral enargite is 48.41% cu, 19.02% as, and 32.57% s by mass. what is the empirical formula of enargite?
LuckyWell [14K]
Empirical formula is the simplest ratio of whole numbers of components in a compound. 
Assuming for 100 g of the compound 
                                Cu                                 As                             S
mass                      48.41 g                          19.02 g                      32.57 g
number of moles    48.41 / 63.5 g/mol      19.02 / 75 g/mol        32.57 / 32 g/mol 
                                = 0.762 mol                = 0.2536 mol            = 1.018 mol 
divide by the least number of moles 
                               0.762 / 0.2536             0.2536 / 0.2536         1.018 / 0.2536
                               = 3.00                          = 1.00                         = 4.01
once they are rounded off 
Cu - 3
As - 1
S - 4
therefore empirical formula is Cu₃AsS₄
