Answer: A suspension is a heterogenous mixture containing large particles that will settle on standing. Sand in water is an example of a suspension. A solution is a homogenous mixture of two or more substances where one substance has dissolved the other.
Answer:
the answer is atmospheric carbon dioxide
Explanation:
Answer:
10.52g KOH
Explanation:
250.0 ml X 1L/1000ml X 0.75 mol KOH/1L X 56.105gKOH/1 mol KOH =10.52g KOH
Answer:
Please take this hepful hint :
F = m * a
6.2 = 2.3 * a
a = 2.7 m/s^2
Explanation:
Answer: C. Gas particles move faster and farther apart at higher temperatures.
Explanation:
The options include:
A. the number of gas particles increases at higher temperatures
B. the number of gas particles decreases at higher temperatures
C. gas particles move faster and farther apart at higher temperatures
D. gas particles move more slowly and get closer together at higher temperatures
The statement that describes how the outcome (dependent) variable changes as a result of the changes made to the tested (independent) variable is that gas particles move faster and farther apart at higher temperatures.
It should be noted that the particles in the gases will collide more frequently with one another because of the shorter space that is between them.
The increase in the temperature will bring about a faster movement of the particles which in turn, brings about a rise in the diffusion rate and also the collision rate.
