Explanation: Chemicals in the original manufacturer’s container that have been recently purchased from a supplier will most likely contain hazard information in the form of warnings and pictograms. Older manufacturer’s chemical containers may have alternative labeling schemes that provide essentially the same information as the new labels.
In drinking water the clear, colorless chemical chlorine might be found. The chlorine is added <span>to drinking </span>water to disinfect it and kill germs. The process is called Water Chlorination. Chlorine is a highly efficient disinfectant. Its purpose in drinking water is to kill <span>bacteria, viruses, and protozoans, that commonly grow in </span>water<span> supply reservoirs, on the walls of </span>water<span> mains and in storage tanks.</span>

The balanced equation for the reaction is
AgNO3 + MgCl2 ==> AgCl + Mg(NO3)2
So it's obvious that for each Mg ion, you'll get 1 AgCl molecule as a product. Now calculate the molar mass of AgCl, starting with looking up the atomic weights.
Atomic weight silver = 107.8682
Atomic weight chlorine = 35.453
Molar mass AgCl = 107.8682 + 35.453 = 143.3212 g/mol
Now how many moles were produced?
0.1183 g / 143.3212 g/mol = 0.000825419 mol
So we had 0.000825419 moles of MgCl2 in the sample of 50.0 ml. Since concentration is defined as moles per liter, do the division.
0.000825419 / 0.0500 = 0.016508374 mol/L = 0.016508374 m
Rounding to 3 significant figures gives 0.0165 m</span>
Answer:
We can distinguish between ethanol and ethanoic acid by reacting them with a metallic carbonate like Na2CO3 or a bicarbonate like NaHCO3 ....... ethanoic acid reacts to give to give CO2 and no reaction takes place in case of ethanol.
