Water acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide. Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.
Calcium carbonate
Explanation:
The chemical most commonly used to counteract the effects of acid precipitation on aquatic ecosystems is calcium carbonate.
Acid rain or acid deposition or acid precipitation is any form of precipitation with an elevated level of hydrogen ion concentration in them.
To nullify this acidic precipitation in aquatic ecosystem, we need to use an environmentally friendly alkaline agent.
The most desired is calcium carbonate. The carbonate neutralizes the acid by producing carbon dioxide, water and calcium salts.
1)
Lets take 100g of this compound.
It contains
50.05 g S and 49.95 g O.
2)
M(S) = 32.06 g/mol
M(O) = 16.00 g/mol
50.05 g S*1mol S/32.06 g S= 1.56 mol S
49.95 g O*1mol O/16.00 g O =3.12 mol O
3) S:O =
=1.56 mol S : 3.12 mol O = (1.56 mol /1.56 mol ) : (3.12 mol /1.56 mol) =1:2
(mol S):(mol O)=1 : 2
SO2
Geiger counter, hope this helps food luck
The answer is D! This adaptation helps the eel fend off potential threats! Hope this helps, have a great day!
