<span>steam at 200°C. particles experience a lot of energy as you increase the temperature.</span>
Multiply the volume by the density. 1 ml = 1 cm^3
1.11 g/cm^3 * 1 cm^3/mL * 386 mL = 428 g
All your units cancel out except for g which is what you would expect since you want units of mass.
Answer:
dS= 1.79*169.504
j/k = 303.41 j/k
Explanation:
Fe3O4(s) + 4H2(g) --> 3Fe (s)+ 4H2O(g)
dS(Fe3O4) =146.4 j/k
dS(H2) =130.684
dS(Fe) =27.78
dS(H2O) =188.825
dSrxn = dS[product]-dS[reactants]
= 3*dS(Fe)+ 4*dS(H2O)-[1*dS(Fe3O4)+ 4dS(H2)]
= [3*27.78 +4*188.825-146.4 -4*130.684] j/k = 169.504 j/k
This is the dS for 1mole Fe3O4
for 1.79 mols Fe3O4
dS= 1.79*169.504 j/k = 303.41 j/k
Answer:
Her Eid per Ruth Jααte Hαin wo Humse,
αb bαtαo Hum Eid Mαnαye yα unko.
ہر عید پر روٹھ جاتے ہیں وہ ہم سے
اب بتاؤ ہم عید منائے یا ان کو
ik ishq ka gam aafat aur us pe ye dil aafat
ya gam na diya hota ya dil na diya hota
bas ek jhijhak hai haal-e-dil sunaane mein,
ki tera bhi jikr aaega mere is phasaane mein.
kya kahoon kis tarah se jita hoon
gam ko khaata hoon aansoo pita hoon
