The following solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations.
Mama L [17]

Answer:

CaCl₂ > CH₃OH = LiCl > C₆H₁₂O₆

Explanation:

The osmotic pressure of a compound is calculated using the following expression:

π = MRT (1)

This expression is used when the substance is nonelectrolyte. If the solution is electrolyte solution then we need to count the van't hoff factor into the expression so:

π = MRTi  (2)

Now, we have 4 solutions here, only two of them are electrolyte solution, this means that these solutions can be dissociated into separate ions. These solutions are LiCl and CaCl₂. It can be shown in the following reactions:

LiCl -------> Li⁺ + Cl⁻     2 ions   (i = 2)

CaCl₂ ---------> Ca²⁺ + 2Cl⁻      3 ions (i = 3)

The methanol (CH₃OH) and glucose (C₆H₁₂O₆) are non electrolyte solutions, therefore they are not dissociated. So, let's use expression (1) for methanol and glucose, and expression (2) for the salts:

CaCl₂:   π = 1 * 3 * RT = 3RT

CH₃OH:   π = 2 * RT = 2RT

C₆H₁₂O₆:  π = 1 * RT = 1RT

LiCl: π = 1 * 2 * RT = 2RT

Finally with these results we can conclude that the decreasing order of these solutions according to their osmotic pressures are:

<h2>CaCl₂ > CH₃OH = LiCl > C₆H₁₂O₆</h2>

Where is the most common place thought of for transformational boundaries?
lana66690 [7]
Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary.

I need help on this please
Montano1993 [528]

Answer:

3

Explanation:

There are three different elements in given chemical equation. These elements are hydrogen, oxygen and carbon.

Chemical equation:

2CH₄ + 4O₂       →       2CO₂ + 4H₂O

This equation shows the burning of methane. When methane burns in the presence of oxygen it produced water and carbondioxide.

We can see that all the reactant and product are made up of only three elements carbon, hydrogen and oxygen.

There are two reactant and two products in given reaction.

This reaction also follow the law of conservation of mass.

We can see that there are two carbon eight hydrogen and eight oxygen  atoms on both side of equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
