Answer:
Belgium and the Netherlands swap land near Lanaye and Oost-Maarland over the discovery of a headless body several years prior, which the Belgian Authorities could not access without crossing Dutch territory. The border has been straightened out and now runs down the center of the Meuse River.[5] The change took effect on 1 January 2018.

Answer:
a. PbSO4, Ksp = 1.7x10^-8.
Explanation:
Hello!
In this case, since the solubility product indicates how likely a solid is able to ionize and consequently dissolve in water, we can infer that the larger the solubility product Ksp, the more ions are able dissolve in water; therefore the proper answer goes with the largest Ksp, which is a. PbSO4, Ksp = 1.7x10^-8 since the power goes closer to 1 than the other options.
Best regards!
Answer:
C2H4I2
Explanation:
Viscosity of a fluid has to do with the internal friction between the internal layers of the fluid.
Molecular weight is found to be related to the viscosity of a fluid even though the relationship may not be strictly linear.
However, the greater the molecular weight of a substance, the greater the viscosity of the material.
Since C2H4I2 has the greatest molecular weight (281.86 g/mol), it is also expected to display the greatest viscosity among all the compounds listed in the question.
After some thinking I have come to the conclusion that the answer is C.
The reaction of hydrogen and nitrogen produces hydrazine. The chemical reaction is expressed as 2H2 + N2 = N2H4. To increase the production of hydrazine, one could increase the amount of the reactants. The reaction is endothermic which means it absorbs heat. Therefore, adding heat would also increase the hydrazine produced.
