Draw the hydrogen bonds between the bases. the letter r represents the rest of the nucleotide. the bases are positioned approximately as they would be in a dna double helix. to indicate a hydrogen bond, simply draw a regular single bond between the atoms. be careful not to modify the existing atoms or bonds in any way, not add extraneous atoms or bonds.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
