Answer is: It is made from the polymerization of a short chain of styrene molecules.

Latex can be found naturally on Earth, but it can also be synthesized using polymers through a process called polymerization. In polymerization, monomers of styrene molecules, emulsified with surfactants, are combined or linked together to make a long chain. Synthetic latex is used in paint and glue because of its ability to dry up into a thin film without releasing a lot of toxic solvents.

For the reaction CO2(g) + H2O(ℓ) + CaCl2(aq) ←→ CaCO3(s) + HCl(aq) K = 4.8 the concentrations of CO2, H2O, CaCl2 and HCl are 0.3

Answer:

3. The reaction will shift to the left.

Explanation:

Hello,

In this case, since we have a heterogeneous equilibrium, and the given equilibrium constant is given in terms of concentration, the law of mass action takes the following form:

$CO_2(g) + H_2O(l) + CaCl2(aq) \rightleftharpoons CaCO_3(s) + 2HCl(aq)$

$K=\frac{[HCl]^2}{[CaCl_2]}$

Clearly, just the hydrochloric acid and the calcium chloride participate in the equilibrium as they are the only aqueous species. Nonetheless, the given concentrations are not defining the equilibrium, therefore, one computes the reaction quotient in order to predict what would the system do to reach equilibrium as shown below.

$Q=\frac{[HCl]^2}{[CaCl_2]}=\frac{ 30.2^2 }{0.652 }=1398.8$

Thus, since Q>K, the reaction will shift leftwards, favoring the formation of reactants, therefore, answer is 3. The reaction will shift to the left.

Best regards.

Why are alloys preferable at times?

andriy [413]

Alloys are preferable at times because they offer interesting properties than pure metal. Alloys are made in order to modify or enhance properties, especially mechanical properties. Examples are stainless steel, brass and wrought iron.
