Answer:(4) Dust particles provide surfaces on which
water vapor can condense
Explanation:
During condensation of clouds dust particles provides spaces where water vapor may condense.
Baking a cake is a chemical reaction due to heat helps baking powder produce tiny bubbles of gas, which makes the cake light and fluffy. Heat also causes protein from an egg to change and make it firm.
Baking powder being CO2
NaHCO3 + NaHC4H4O4 ===> Na2C4H4O4 + CO2(g) + H2O
The activity coefficient of h is 0.05
The ph of the solution is 2.08
To find the activity coefficient, apply the concept of ionic equilibrium
h( activity coefficient)= 1/2CZ²
C is the concentration of species
Z is the charge on individual species
<em>h= 1/2( 0.01 x1²+ 0.04x (-1)²+0.01 x1²+0.04x (-1)²)</em>
<em>h= 0.05 </em>
For the pH of the solution, apply the formula
<em>pH= -log( H⁺x0.83)</em>
<em>pH = - log(0.01x0.83)</em>
<em>= 2.08</em>
