How would a solution that is labeled 5.0 molar be similar to one labeled 5.0 molal?

Answers

Answer 1
Answer: They might share some similarities but definitely they do not mean the same. Both are expressions of concentration of a substance. Molarity is the number of moles per  unit of volume of the solution while molality is the number of moles per mass of solvent. In this case, they both are similar in having 5 moles of the substance.

In most aqueous reactions as temperature increases, the effectiveness of collisions between reacting particlesA. decreases
B. increases
C.remains the same

Answers

The reactions that occur in or in the presence of the water is called aqueous reactions. As the temperature increases, the collision of the particles also increases.

What kinetic energy and its relationship with temperature?

The increase of the temperature affects the collision rate of the particles which can be explained by the kinetic theory.  The increase in the temperature increases the collision of the particles.

The increased temperature increases the number of collisions and the kinetic energy that is enough to overcome the activation energy required by the particle to start the reaction.

Therefore, an increase in temperature option B. increases the particle collision.

The more energy the more aqueous. Which can affect collision into increasing. Meaning B. increases :)
