HELPP Based on the nature of the reactants, which reaction below will occur at the fastest rate at 84°C ?
1. 2KCIO,() 2KCI(s) + 30,(g)
3. N.(g) + 3H2(g) → 2NH,(g)
7. H(aq) + C, H,O, (aq) » HC, H,O,
8. C(s) + O2(g) → CO
(G)

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

Hey can you me with this i really need y’all
