Answer:
Explanation:
(a) Balanced equation
2Fe + 3Cl₂ ⟶2FeCl₃
(b) Calculation
You want to convert moles of Cl₂ to moles of Fe.
The molar ratio is 2 mol Fe:3 mol Cl₂
Just because they have same atomic masses doesn’t make them similar. They have different chemical properties because they are made of different things. And physical properties because they form different bonds with different atoms in the process.
Answer: The final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Explanation:
It is known that the heat capacity of ethylene is 2.145 J/g K. Hence, for 10 moles of ethylene its mass will be as follows.
No. of moles =
10 mol =
mass = 280.5 g
Now, we know that relation between heat energy, mass and specific heat is as follows.
q =
1329.63 = T - 473
T = 1802.63 K
or, =
=
Thus, we can conclude that the final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Bromine is less electronegative than chlorine, yet methyl bromide and methyl chloride have very similar dipole moments. This is because the bond distance in methyl bromide is more due to the large size of bromine atom.
Dipole moment is calculated by multiplying the charge on the atom with the bond distance.
