(you and explain! ) here are two questions:
"the most common form of nylon (nylon-6) is 63.68% carbon, 12.38% nitrogen, 9.8% hydrogen, and 14.14% oxygen. calculate the empirical formula for nylon-6."
"there are two binary compounds of mercury and oxygen. heating either of them results in the decomposition of the compound, with oxygen gas escaping into the atmosphere while leaving a residue of pure mercury. heating 0.6498 g of one of the compounds leaves a residue of 0.6018 g. heating 4.172 g of the other compound results in a mass loss of 0.016 g. determine the empirical formula of each compound."
you for your !

The answer for the first problem is:  C₆N₁H₁₁O₁ or C₆NH₁₁O

Explanation:

Nylon composition:                     Mass        Divide by the atomic mass

Carbon                   63.68 %      63.68 g         63.68/ 12    = 5.3

Nitrogen                 12.38 %       12.38 g          12.38/14     = 0.88

Hydrogen                  9.8%           9.8 g           9.8/1           = 9.8

Oxygen                    14.14%         14.14 g          14.14/16      = 0.88

We choose the lowest number that is 0.88 for nitrogen and oxygen and divide the four results by this number

Carbon     5.3/0.88 = 6

Nitrogen    0.88/0.88 = 1

Hydrogen   9.8/0.88 = 11.1  = 11

Oxygen     0.88/ 0.88 = 1  

Then the empirical formula has this coefficients

        C₆N₁H₁₁O₁ or C₆NH₁₁O

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
