Answer:
Answer is D. All of the above
The health hazards because it is asking which human risk is the most important to consider.
The equilibrium expression shows the ratio
between products and reactants. This expression is equal to the concentration
of the products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l)
= H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
Imagine A is a Heterogeneous mixture because it a mixture composition that does not stay the same throughout the mixture.
Imagine B is the Homogeneous mixture because it has no changes or irregularities
