Answer:
C
Explanation:
Please see the attached picture for the explanation.
<u>Le Châtelier's principle</u><u>:</u>
When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.
• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.
☆ Why can heat be written on the same side of the products when the reaction is exothermic?
• Exothermic means that heat is released, thus heat can be treated as a product.
• I like to remember it as Exothermic → Exit
Answer:
How do the water molecules closest to the burner compare to the water molecules closest to the surface of the liquid? ... They are closer together and moving slower than those at the surface. They are more spread out and moving faster than those at the surface. The diagram shows the sun's interior.
Explanation:
Answer: (3) carbon dioxide
Explanation: Solubility of solids and liquids is not affected by pressure as they are highly incompressible. Methanol is liquid, carbon dioxide is a gas, sugar is a solid and sodium nitrate is also a solid.
But solubility of gases is affected by pressure as they are compressible and the solubility is governed by Henry's law, which states that mass of gas dissolved in a given liquid ta constant temperature is directly proportional to the pressure of the gas present in equilibrium with the liquid.
Increase in pressure increases the solubility as increase in pressure would lead to decrease in volume of gas particles and hence more number of particles will be present per unit volume and as a result, the number of particles striking the surface of solution and entering the solution will increase. Thus solubility increases.
Answer:
The disadvantages or the limitations are as follows:
Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons
Arrow and line diagrams: Does not say much of the possible properties of the molecule.
Written electron configurations: no 3D representation of the molecule or the atom

Answer:
The molarity of a sugar solution is 2 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
4 L of solution--------8 moles of sugar
1 L of solution ------x= (1 L of solution x 8 moles of sugar)/4 L of solution
x=2 moles of sugar---> <em>The solution is 2M</em>
