Answer:
Polluted ground water.
Explanation:
The rocks through which water flows into the ground sieves most of the contaminants whose molecules are larger than most bacteria. Such molecules include but are not limited oil molecules. Therefore as it descends to the lower levels of the soil profile, water is subjected to continuous filtration by the layers and it is the least susceptible to contamination by oil spills.
Reactants: H₂SO₄ + 2 NaOH
Products: 2 H₂O + Na₂SO₄
The answer is A.
Condensation goes with A.
Evaporation goes with C.
Sublimation goes with B.
Freezing goes with D.
Answer:
Kp = 41.53
Kc = 1.01
Explanation:
To calculate the equilibrium constant in terms of pressure, what we simply do is to use the equilibrium pressure raised to the power of the number of moles. What we are saying in essence is this:
Kp = [NOCl]^2/[NO]^2[Cl]
Kp= [0.25]^2/[0.174][0.093]^2 = 41.53
Kp = Kc (RT)^Dn
Hence, Kc = Kp/[RT]^(delta n )^-1
n = sum of the number of moles of products minus the sum of the number of moles of reactants= 2-3 = -1 in this case
Kc = 41.53/(0.0821 * 500)^1
Kc = 1.01
Answer: Tyndall effect is the scattering of light due dispersed colloidal particles that does not settle in a solution. Colloidal particles constantly moves because of Brownian motion and blocks or hinders light particles to pass through. Colloidal particles are medium sized particles but smaller enough than suspension.
