Answer: Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
process by which one separates compounds from one another by passing a mixture through column that retains some compounds longer than others.
Answer: Option (d) is the correct answer.
Explanation:
When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.
Therefore, kinetic energy of the water particles decreases.
<span>henry's law :
S</span>₁ / P₁ = x / P₂
7.5 / 404 = x / 202
x = 7.5 * 202 / 404
x = 1515 / 404
x = 3.75 g/L
hope this helps!
