A rock can be broken down into different kinds of substances by physical processes. No chemical reactions are needed to separate
denpristay [2]

Answer:

I believe the correct answer is a mixture. Most rocks are just different compounds or elements somewhat fused through heat and pressure. The substances are not chemically bonded together which means that they all retain their chemical identity and therefore can be separated by breaking them up. A good example of this is granite where you can see the different compounds that got fused together and can falls apart when you grind it. I hope this helps. Let me know if anything is unclear.

Explanation:

HOPE THIS HELPS :)

A particular 3.0 L solution contains 2.5 mmol (millimoles) of a substance. What is the concentration of this solution in number
bearhunter [10]

Answer: 0.83mol/m3

Explanation:

Number of mole = 2.5 mmol = 0.0025mol

Recall

1L = 0.001m3

Therefore 3L = 3x0.001 = 0.003m3

0.003m3 contains 0.0025mol

Therefore, 1m3 will contain = 0.0025/0.003 = 0.83mol

The concentration in mol/m3 is 0.83mol/m3

<h3><u>Answer;</u></h3>

10 percent

<h3><u>Explanation;</u></h3>
  • Probability is a number that describes how likely it is that an event will occur.
  • In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
  • Therefore; as a percentage;

1/10 × 100 = 10 percent

  • Hence; The probability of each individual event occurring is 10 percent
