Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
Answer:
The density is 2.5625g/mL. Hope this helped! :)
Explanation:
M= 8.2g D=M/V
V= 28.3-25.1=3.2mL
D=8.2g/3.2mL
D= 2.5625g/mL
Answer:
ΔS = - 0.125 Kj/K decreased entropy
Explanation:
From ΔH = TΔS => ΔS = ΔH/T
= 100Kj/(600K - 1400K) = - 188Kj/800K = - 0.125 Kj/K
Entropy in the cooler flask would have 'decreased' (i.e.; more ordered state) at 600K.
Answer:
Eroision: waterfall, oxbow lake, meander.
Deposition: flood plain, alluvial fan, delta. hope this helped
The answer is (4). All compounds of sodium and of perchlorate are soluble in water.
