Draw the product of the following diels-alder reaction. indicate stereochemistry where appropriate (use hashed bonds to denote endo substituents and wedged bonds to denote exo substituents).

  the volume of  0.220 m k2s    solution  required  to  completely  react with 175 ml  of 0.115m co(no3)2  calculate the moles  of co(no3)2 =  molarity x volume/1000175 x0.115/1000= 0.02  moleswrite  the reacting  equationk2s(aq)  +  co(no3)2  = 2 kno3(aq)  + cos(s)by  use  of mole ratio between k2s to co(no3)2 which  is  1: 1 the moles of k2s is therefore = 175  x0.115/1000= 0.02  molesvolume = moles/molarity=0.02/0.22=0.09  ml  of k2s

The nationalists army held a higher advantage because of the ammount of men in the army. outnumbered them up to 3 over 1.

Answer

nitrogen fixation is the process of fixing gaseous nitrogen to usable forms while in decomposition the source of nitrogen is organic waste.

explanation

fixation

nitrogen in its gaseous form (n2) can’t be used by most living things. it has to be converted or ‘fixed’ to a more usable form through a process called fixation.

biologically: nitrogen gas (n2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (nh4+), which can be used by plants.

decomposition:

plants take up nitrogen compounds through their roots. animals obtain these compounds when they eat the plants. when plants and animals die or when animals excrete wastes, the nitrogen compounds in the organic matter re-enter the soil where they are broken down by microorganisms, known as decomposers. this decomposition produces ammonia, which can then go through the nitrification process.
