(Note: I know that the VSEPR method fails sometimes, and that there are exceptional molecules. The challenge is about the molecules which conform.) Most people who have taken an introductory ...
Introduction What you have to do is, given an an ASCII diagram of a chemical, output the chemical formula. Rules Your code must not access the internet and may not use a stored library of ...
There are more than 100 elements in the modern periodic table. You challenge is to output the rounded mass of an element with respect to the input given. Input Input will contain an abbreviation of ...
Challenge Given two inputs, a positive ion and a negative ion, you must output the formula for the ionic compound which would be made from the two ions. This basically means balancing out the charges ...
Your task is to take an string containing an isotope of an element as input, encoded like the following example with the atomic number followed by a space and the IUPAC chemical symbol for the ...
As you may know, in DNA there are four bases — adenine (A), cytosine (C), guanine (G) and thymine (T). Typically A bonds with T and C bonds with G, forming the "rungs" of the DNA double helix ...
Based on Practical Golf - US States Your task is to find the abbreviation (symbol) of an element given the element name, up to and including ununoctium (118). Use the periodic table on Wikipedia. ...
Electron Configurations Your mission is to accept an element's atomic number as input, and output its electron configuration (e.g. 2,8,8,2 for calcium). Input An atomic number from 1 to 118. You ...
Given a sequence of the bases Adenine, Cytosine, Guanine and Thymine (encoded as ACGT), you're to produce an ASCII art representation of a corresponding double strand of DNA. The strand will extend ...
Task Write a program that takes in a compound made solely of elements with an atomic number less than or equal to 92 (Uranium), and outputs the molar mass of the compound in grams/mole. Rules and ...
An ionic compound is named like so: (metal name) (non-metal suffixed with -ide). Here is a list of all the suffixes that need to be replaced with -ide: -on -ogen -ygen -ine -orus -ur -ic -ium The ...
Bernd is a highschool student who has some problems in chemistry. In class he has to design chemical equations for some experiments they are doing, such as the combustion of heptane: C7H16 + 11O2 ...
