The question is incomplete, the complete question is;
A magnet was placed near a pile that contained both iron and sulfur. The magnet was moved gradually closer to the pile. As it neared the pile, the magnet started attracting small pieces of iron from the pile. Which of these statements best describes the contents of the pile?
F. It is a homogeneous mixture of iron and sulfur. G. It is a heterogeneous mixture of iron and sulfur. H. It is a compound that contains both iron and sulfur. I. It is a compound that can be separated by magnetism.
Answer:
G. It is a heterogeneous mixture of iron and sulfur.
Explanation:
A heterogeneous mixture is one that does not have a uniform composition throughout.
We must recall that a mixture is any combination of substances that do not chemically react together and are separable by physical means.
Having said this, it is clear that I can separate the iron from sulphur by simple magnetic (physical) means. Hence, it is a heterogeneous mixture of iron and sulfur.
Answer:
x-10 should be the answer
I think the correct answer is c if not it’s d
Answer:
- <em><u>Option a. no change</u></em>
Explanation:
The question makes sense only if the equation is an equilibrium reaction:
- <em>4A (g) + 5B (g) ⇄ 2C (g) + 7D (g) </em>
This is, A and B react to produce C and D, forward reaction; and C and D react to form A and B, reverse reaction.
Then, you can study the effect of increased pressure using LeChatelier's principle.
To counteract the disturbing effect produced by increased pressure on the equilibrium, the system will react shifting the toward to the side where the pressure could be decreased.
That would be toward the side that has less gas molecules.
Since both sides have 9 molecules (4 + 5 = 2 + 7 = 9), the equilibrium concetrations will not change.
That is represented by the first choice: no change.
Answer:
The term “flat bone” is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.
HOPE THIS HELPS!!! :D
