The correct answer is option d, that is, the solubility of a solid is highly dependent on temperature.
Solubility refers to the maximum amount of a component, which will get dissolved in a given concentration of solvent at a particular temperature. The temperature influences the solubility of both gases and solids. The temperature has a direct influence on solubility.
For most of the ionic solids, enhancing the temperature elevates how briskly the solution can be formed. With the increase in temperature, the movement of the solid particles takes place briskly that enhances the chances that they will associate with the majority of the solvent particles. This leads to enhancing the rate at which the solution takes place.
Answer:
Different substances have different molecular masses. Thus, equal masses have different numbers of atoms, molecules, or moles. On the other hand, equal numbers of moles of different substances have different masses.
Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
Answer:
B. observing that a bone placed in a beaker of acid becomes bendy
Explanation:
The hypothesis suggests that when chicken bones are placed in vinegar, they become bendy due to the loss of calcium in their bones.
Calcium is identified as the ossifying material that strengthens the bone. When the acid that makes up the vinegar comes in contact with it, calcium is removed from the bone.
Now we know that calcium has capabilities of reacting with acids.
This suggests that if we also place the bone in an acid, they will bend due to reaction of calcium in the bones with the acid.
Answer:
Gaseous solution isn't dense, neither the solid, but liquid is denser
Explanation:
Gas: only gases are dissolved under a given set of conditions.Since interactions between molecules play almost no role, dilute gases form rather trivial solutions. In part of the literature, they are not even classified as solutions, but addressed as mixtures.
Liquid: If the solvent is a liquid, then almost all gases, liquids, and solids can be dissolved.
Solid: Solid solution is less denser than liquid.
