Explanation:
Neutralization reaction between magnesium hydroxide and hydrochloric acid Mg(OH)2(s) + 2HCl(aq) → 2H2O(l) + MgCl2(aq) b.
so uh pretty sure Mg(OH)2(s) + 2HCl(aq) → 2H2O(l) + MgCl2(aq) b.
correct me if im wrong <3
Answer:
A substance containing only one type of atom or one type of molecule is a pure substance. Most of the matter around us, however, consists of mixtures of pure substances. Air, wood, rocks and dirt are examples of such mixtures. Mixtures can be further classified as Homogeneous and Heterogeneous.

The Mesosaurus could not swim between the continents in the open ocean, so the fossils show that the continents must have been together in the past.
Explanation:
One critical point in the use of Mesosaurus to explain continental drift is that they could not swim between the continents in open ocean.
Mesosaurus is known as middle lizard and its fossils have been used to proof that continental drifts truly result. Alfred Wegener is credited with the hypothesis of continental drift in which the land masses where once joined together.
- The fossils of this ancient organism have been discovered in the Southern part of Africa and Eastern part of South America.
- Both continents were once believed to be joined together in geologic time past.
- Mesosaurus was a swamp dwelling animal that could not have swim between the two continents. The ocean will pose a barrier. For its fossils to be found on the two continents, the land masses must have been joined together.

Answer:
I > III > II
Explanation:
The osmotic pressure (π) is a colligative property that can be calculated using the following expression.
π = M × R × T
where,
M is the molarity of the solution
R is the ideal gas constant
T is the absolute temperature
As we can see, there is a direct proportionality between the molarity of the solution and its osmotic pressure. As a consequence, the correct order for osmotic pressures is:
I > III > II
