Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
Surface tension is the result of water molecules pulling inward with a strong attractive force.
The attractive force brings the molecules on the surface of the water close together.
The attractive force causes the surface of the water to be drawn toward the water molecules beneath the surface. <span>
Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.</span>
Answer:
The explanation to your question is below.
Explanation:
In thermochemistry, reactions are classify in two groups.
- Endothermic reactions: are reactions that need energy (heat) from the surroundings to happen. If they are not heated, the products will not form.
Example:
2 H₂O + energy ⇒ 2H₂ + O₂
-Exothermic reactions: are reactions that release energy to the surroundings. They happen spontaneously.
Example:
CH₄ + 2O₂ ⇒ CO₂ + 2H₂O + energy (heat)
The answer is covalent bonding. Molecular compounds are made of 2 or more nonmetals, and are therefore covalent. That is why another name for "molecular compound" is "covalent compound".
Answer: (1) covalent bonding
Hope this helped!! :D
