Ammonia is produced synthetically by the reaction: 2fe+3cl2 2fecl3 - is this an exothermic or endothermic process? - how many moles of nh3 are formed when 1 mol of n2 reacts with hydrogen? -if 18 x 1023 molecules of h2 react with nitrogen, how many moles of nh3 are produced?

Ammonia is synthetically by reaction

N2 +3H2 ---> 2NH3

(a) The process is exothermic. This is because heat is released during the formation of NH3(ammonia)

(b) The moles of NH3 formed when 1 mole of N2 reacted with hydrogen is 2 moles

by use of mole ratio between N2 to NH3 wich is 1:2 the moles of NH3 is therefor = 1 x 2/1 = 2 moles

(c) The moles of NH3 produced if 18 x10^23 molecules of H2 reacted is 1.993 moles of NH3

calculation

by use of Avogadro law constant calculate the moles of H2 reacted

1 mole = 6.02 x 10^23 molecules

? = 18 x10 ^23 molecules

by cross multiplication

= 1 mole x 18 x10 ^23 / 6.02 x10^23 = 2.99moles of H2

by use of mole ratio of H2 : NH3 which is 3:2 the moles of NH3 is therefore= 2.99 x/3=1.993 moles

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
