Answer:
2.73 is the equilibrium constant for the dissociation of 
gas at 840 degree Celsius.
Explanation:
Initial
0.600 atm 0
Equilibrium
(0.600 atm - p) 2p
Total pressure at equilibrium = P = 0.984 atm
P= 0.600 atm - p)+2p=0.984 atm
p = 0.384 atm
Partial pressure of the gas , 
= (0.600 atm - 0.384 atm)=0.216 atm
Partial pressure of the 
gas, 
= 2(0.384 atm)=0.768 atm
2.73 is the equilibrium constant for the dissociation of gas at 840 degree Celsius.
Sugar burns and turns black. A completely new substance was formed, which is the main pointer for it being a chemical reaction. More evidence would be change of color, odor, and the fact that flammability is a chemical property so setting something on fire would be a chemical change.
Answer:Seeds are great sources of fiber. They also contain healthy monounsaturated fats, polyunsaturated fats and many important vitamins, minerals and antioxidants. When consumed as part of a healthy diet, seeds can help reduce blood sugar, cholesterol and blood pressure
Explanation:
Answer:
cW = 4.2J/g.k
Explanation:
Heat gained = Heat lost
iron(mc∆€) = water(mc∆€)
mi= 100g
ci = 0.449
∆€i= 150-25 = 125
...
mw= 268.5g
cw = ?
∆€w=25-20 = 5
...
100×0.449×125= 268.5×cw×5
5612.5= 1342.5cw
cw = 5612.5/1342.5
cw= 4.18 ~ 4.2J/g.K
