The tricky bit with color is that we don't see frequency along a single band. Rather, there are 3 bands (RGB) that get added together (plus a fourth input for brightness as well as many sub-processes that deal with textures and patterns). Light of a single frequency excites one band a lot, the other a little, and the last almost none. This sum is what we percieve. Some people are missing a band (usually blue or green) causing color blindness. Either way, a rainbow looks continuous but by mixing light there are many ways to generate the same color. It's all a bit dirty.

The other stuff seems to confuse the idea of error, eg you seem to think "quantity + error = quality". But in such cases, error is usually known (and compensated for) turning the equation into the sum of two 'knowns', leading to another 'known'.

1. Why is soil erosion relatively less in dense forests as compared to barren, open fields?
vredina [299]

Because the deep roots of big trees hold the soil and don't let it slip away simply by rain or wind.

Name the following alkane:
vladimir1956 [14]

The names of the alkanes are 2,2- dimethylbutane, 2,4- dimethylhexane, 2,2,3,3- tetramethylbutane and 4- ethyl, 3,6- dimethyl heptane.

Alkanes are saturated hydrocarbon in the organic chemistry. These are organic compounds that consists of single bonded carbon and hydrogen atoms. The common formula for writing an alkane is given by CₙH₂ₙ₊₂.

Alkanes are further divided into three more types which are:

1. Chain alkanes

2. Cycloalkanes

3. Branched alkanes

Hydrogenation method is used for preparation of alkanes from alkene and alkyne.

The names of the given compounds are:

Part A:

2,2- dimethyl butane

Part B:

2,4- dimethyl hexane

Part C:

2,2,3,3- tetramethyl butane

Part D:

4- ethyl, 3,6- dimethyl heptane

Learn more about alkanes from the link given below.

If 1.00 g of a hydrocarbon is combusted and found to produce 3.14 g of co2, what is the empirical formula of the hydrocarbon?
photoshop1234 [79]
The combustion reaction is as expressed,

                CxHy + O2 --> CO2 + H2O

The mass fraction of carbon in CO2 is 3/11. Hence,
       mass of C in CO2 = (3.14 g)(3/11) = 0.86 g C.

Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g. 

     moles of C = 0.86 g C / 12 g = 0.0713
     moles of H = 0.14 g H / 1 g  = 0.14

The empirical formula for the hydrocarbon is therefore, CH₂.
