Question

do plz.. tomorrow xammmm

Answer 1

✷✷GOOD EVENING FRIEND✷✷

I can see a lot of questions there...IT'S VERY DIFFICULT TO ANSWER ALL QUESTIONS SEPARATELY...SO I WILL GIVE HERE SOME MAIN CONCEPTS...AND THEN TRY URSELF...IF U FIND ANY DIFFICULTY U CAN ASK UR DOUBTS IN COMMENT SECTION.

▶Let's Take 1st question as an Example to explain all my points...

➠➠1. Always, in any problem related to moles and mole concept...The very first thing to do is to Write a Balanced chemical equation

Nitrogen reacts with hydrogen to give ammonia..given in 1st question

N2+ 3H2➠2NH3. is the Balanced chemical equation.

➠➠2. One mole= 6.022* 10^23 molecules(let's represent it as N for our convenience)

➠➠3. One mole=22.4 L

➠➠4. One mole= Molecular or atomic weight in grams.

Now taking 1st question as an example to explain points 1,2, and 3.

N2+ 3H2➠2NH3

⇝We have 1 mole N2..3 mole H2...2 mole NH3...

⇝We have N molecules N2...3N molecules H2...and 2N molecules NH3..

   Where N=6.023 * 10^23

⇝We have 22.4L N2...(3* 22.4 L) H2....And (2* 22.4 L) NH3

⇝We have 28 gm N2 ..(2*14)..6 gm H2(3*2.)...We have 34 gm NH3(2* 17)..

HOPE THIS HELPZ U
