The fact that when in solution <span>C</span>₂<span>H</span>₅<span>OH conducts electricity means that it is an electrolyte so you can automatically cross out A and C (the definition of an electrolyte is a substance that will conduct electricity when in a solution). I think the correct answer is B due to the -OH group (the - indicates a covalent bond) which allows the molecule to give up a proton (H</span>⁺).
I hope this helps. Let me know if anything is unclear.
D. through measuring and observing !
The net ionic equations in
the creation of solid Hg2Cl2 and aqueous Sodium Nitrate (NaNO3) would be:
Hg2(NO3)2 + 2 NaCl
--------> Hg2Cl2 + 2 NaNO3 <span>
Hg2+2 + 2NO3-1 + 2Na+ Cl- ----> Hg2Cl2 + 2Na+ + 2NO3-1
<span>Hg2+2 + 2Cl-1 ------------> Hg2Cl2</span></span>
Answer:
2nd and 4th ones
Explanation:
More sugar dissolves in water than salt
more aspirin dissolves in water than CO2 ...but less aspirin than table salt (NaCl)
K will always have an oxidation state of +1. Now O is -2 except in peroxides, this is not a peroxide, so total charge will be -6, if you subtract the +1 of K from it, it leaves -5 charge to be neutralized by Cl in KClO3, so Cl will be +5. In the product side, K will still have the same oxdiation which is +1 and Cl would have -1. O2 will have zero. <span>Now, Cl is gaining the electrons to go from +5 to -1, so it is getting reduced while O2 is losing electrons to go from -2 to zero so it is getting oxidized.</span>
