The electrons are transferred when the reaction is redox reaction. It means that there must be reduction and oxidation.
The given equation is
The oxidation number of each element remains the same before and after the reaction.
H = +1
C: +4
O: -2
N: -3
Thus this is simple acid base reaction and not redox
There is transfer of proton from bicarbonate to ammonia
this is not a redox reaction
Potassium Chloride = KCl
KCl has a molar mass of: 39.0983g+35.4530g=74.5513g
The number of moles of KCL we are adding is:
2g/(74.5513g/mol) = 0.02683 mol
But you have to keep in mind that salts in
water dissociate:
KCl -> K+ + Cl-
So 1 mole KCl is 2 osmoles (because it’s
two particles)
So if you add 0.02683 moles, you are adding
0.02683*2 = 0.05366 osmoles.
If you dissolve them in 1 liter, you have a solution 0.05366 OsM = 53.66 mOsM
D5W = dextrose 260 mOsM
1/2 Normal Saline =
has half of the normal saline concentration - a normal saline solution has the
same sodium chloride concentration as blood serum = 154 mOsm
You have to sum up all the osmolarities:
<span>= </span>53.66 mOsM + 154 mOsM + 260 mOsM = 467.66 mOsM

Explanation:
This reaction is known as mercuric ion catalyzed hydration of alkynes.
The first step in the reaction is attack of the mercuric ion on the carbon-carbon triple bond, a bridged intermediate is formed. This bridged intermediate is attacked by water molecule to give an organomercury enol. This undergoes keto-enol tautomerism, proton transfer to the keto group yields an oxonium ion, loss of the mercuric ion now gives equilibrium keto and enol forms of the compound. The keto form is favoured over the enol form.
45,000 written in scientific notation would be 4.5×10⁴.
The number first has to be written so that there's only one number to the left of the decimal point.
4.5000
The decimal point would have to be moved 4 places to the right for the decimal to become 45,000 again. Therefore, the exponent on the 10 would be positive 4.
There is a place in Upper Peninsula that is named Iron or Iron Mountain.
