Answer:Iodine:
Electron configuration:
[Kr]4d10 5s2 5p5
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5
Explanation:
Iodine is an element in group 17. It has only on umpired electron in the 5p orbital it combines with fluorine which also has one unpaired electron in its outermost orbital to form different complex interhalogen compounds by covalent bonding. These interhalogen compounds exhibit various shapes and properties.
Answer:
H2CO3,HCl
Explanation:
the rest are not acids but I arrange the acids based on their number of hydrogen
Molality of C2H5OH is 1.1.27m.
What is Molality?
Molality is no.of moles present in One Kg solution .
Molality is represented by m
m= no.of moles/ weigt of solution in kg
Given is Molarity= 51.30M
molar mass of C2H5OH is 46g / mol , Density =0.9349g/ ml
Density=m/V
V = 107 ml
Molarity= no of moles/ Volume
51.5×46×107= x × 1000
weight of C2H5OH = 27.7g
molality = 27.7/1000××46
m= 1.27m

Continental drift– the theory that the continents are moving very slowly.Fossil– the remains, traces, or imprint of an ancient living thing preserved in rock.Glacier– a large, slowly moving body of snow and ice.Ice age– a time when Earth was very cold and large areas were covered by glaciers.Landmass– a large, unbroken ...
Explanation:
Answer: I am not sure but I think its fossil fuel - filling oil and mining coal cause few environmental problems,not dependent on weather condition, not chemical hazard or flammable hazard. Wind and solar - inexpensive, increase carbon footprint and easily stored and transported
Explanation:
I am not quite sure for two of them
