Answer:
D: Increasing temperature
Explanation:
From collision theory, we know that the more the increase in collisions, the faster the rate of the chemical reaction.
Now, the amount of solid solute in a solvent will change with a corresponding change in temperature. What we mean is that, the higher the temperature increases, the higher the number of collisions between the solvent molecules as well as leading to an increase in the solute particles which will mean an increase in the amount of the solid solute dissolved. The correct answer is option D.
Answer: See attached image
Explanation:
The type of mixture that is formed when one substance dissolves into another and fills the spaces between other kinds of molecules is a colloidal mixture. It is a type of mixture where a solute is dispersed evenly in a solvent. The particles' sizes range from 1 to 1000 nm.
Answer:
The foam board has a larger gravitational force but it also has a very large air resistance force. The net (total) force on the foam board will give it a smaller acceleration than paper.
Explanation:
The air molecules get knocked away and take some of the kinetic energy away from the object, which makes the object slow down
Answer:
4.62
Explanation:
Using the equation -log[H3O+] = pH,
-log(2.4 x 10^-5) = 4.62
