none. its a triple bond. N≡N

You can predict the base seqences of a DNA molecule if you know what one strand is, because of double Stranded DNA. Each strand matches up with a letter and repeats a pattern throught the entire DNA strand.
At normal atmospheric pressure, nitrogen is gaseous over the entire liquid range of water (and considerably below as well; the boiling point of nitrogen is about 77 K).
NH4+, or ammonium, has a tetrahedral shape with a covalent bond angle of 109.5 degrees between the hydrogen atoms. The bond length of the nitrogen-hydrogen bond is about 1.04 Angstroms.

Why is it impossible to make double bonds between nitrogen and oxygen? Who said it is impossible!! N has 5 valence electrons and O has 6 valence electrons. When you try to draw the structural formula of an N-O compound you have an extra electron. However, you can draw the structural formula of N2O4. Look it up on the web. It has 2 double bonded N=O and 2 single bonded N-O. New concept! The bonds are called resonance bonds, because one pair of electrons from each of the double bonds moves around the entire molecule. Thus the molecule is symmetrical. You need to see an image of this on the web understand it better!!
Since we need the mass percent, we need to know the molar mass of the entire compound: H - 1g/mol N- 14 g/mol O -32 g/mol (16 g/mol x 2) which equals 47 g/mol. now, put the weight of the unknown, N, over the entire weight. 14/47 = 29.8 g/mol
yes, the entire molecule forms a straight line
The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
