The protons are equivalent to the atomic number, so we can determine that the element being expressed here is Magnesium. If you are ever stuck on what element you are finding your information from, just remember that the number of protons is the exact same as the atomic number in ANY situation :)
The charge of magensium is +2, with an atomic mass of 24. So A would be your answer :)
Answer:
The term reduction means you are reducing the componenets of the air.
Explanation:
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Dissolution of solids into liquids is defined as the dissolving of solid particles in liquid.
Rate of dissolution of solids in liquids depend on 4 main factors:
1.) Temperature: Increasing the temperature means more solute can be dissolved in the given amount of solvent because the energy of the solute particles increases and more it can interact with the solvent particles. The rate of dissolution of solid also increases in liquids.
2.) Size of the solute particles: If the solute particles is present in smaller size, more it can be dissolved because this action takes place on the surface of particles and decreasing the size increases the surface area of the solute particles. Hence, increasing the dissolution.
3.) Stirring: This process brings fresh solvent particles to come in contact with the solute particles and hence, fast stirring increases the rate of dissolution.
4.) Amount of solute already present in solvent: If more amount of solid is already present in the solvent, the dissolution rate decreases.
From the above information, the correct answer is Option B.
