It knows that when water evaporates, it carries heat energy away with it.
So your body puts some water out on your skin, and hopes that it will
evaporate. We call that "perspiring" or "sweating".
Balanced equation:
Ca(OH)2+H2SO4=CaSO4+2 H20<span />
26g --- 1 mol
56g --- X
X= 56/26 = 2,154 mol
959 ml = 959cm³ = 0,959dm³
C = n/V
C = 2,154/0,959
C = 2,246 mol/dm³
Answer :
Option D) 2.50 X Mol/(L s)
Explanation: While calculating the average reaction rate for the given reaction in terms of Cl;
.
using the rate equation which is;
=
=
2.50 X Mol/(L s)
