Answer:
K = 1.08 X 10¹²
Explanation:
The solved solution is in the attach document
2Al + Fe2O3 ——-> Al2O3 + 2Fe
This is a single displacement reaction
The mass of the piece of lead is calculated using the below formula
Q(heat)= mC delta T
Q = 78.0 j
M=mass =?
C=specific heat capacity ( 0.130 j/g/c
delat T=change in temperature = 9.0 c
by making M the subject of the formula
M = Q/ c delta T
M= 78.0 j/ 0.130 j/g/c x 9.0 c = 66.7 g of lead
Answer:
The products will also have one S and four O atoms.
Explanation:
According to Law of Conservation of Matter, " Matter can neither be created nor destroyed, but it can be changed from one form into another".
The branched structure isomer will require less energy to melt than the straight chain isomer
explanation
Branched structure isomer has weak intermolecular forces of attraction as compared to straight chain isomers. In addition the branched isomer has a low boiling point as compared to straight chain isomers. Since boiling require the of the intermolecular forces tend to have lower boiling point than straight chain
