A mixture in which composition is constant throughout the mixture is said to be homogeneous mixture.
Now, oil and vinegar dressing is not considered as a homogeneous mixture because composition is not uniform.
Concrete is made up of three components. Thus, composition is not uniform, so it is not a homogeneous mixture.
A mixture of salt and pepper, when salt is mixed in pepper then the mixture is not uniform as white flecks of salt and black flecks of pepper can be seen in the mixture. Thus, it is not a homogeneous mixture.
Salt water is uniform mixture. Thus, it is a homogeneous mixture.
Thus, salt water is the correct answer.
Answer:
has large mineral crystals
homogeneous mixture not pure, but is spread out the same throughout
concentration, a measure of the amount of solute dissolved in a solvent
mixture,two or more substances that do not chemically combine, salt and pepper
solute,substance that is dissolved in the solution
Answer:elementary substance
Explanation:
Law of superposition
Principle of cross-cutting
Explanation:
The geologic precepts that would be used to determine the relative ages of the rock strata are the law of superposition of strata and the principle of cross-cutting.
- The law of superposition of strata states that "in an undisturbed sequence of rock strata, the oldest layer is usually at the bottom and the youngest on top".
- From this law we understand that the oldest layer will be at the bottom if the rock has not been disturbed.
- Here the rock has been disturbed by folding and we need to unravel to fold and see how the rock sequence originally was laid.
The principle of cross-cutting states that "faults are younger than the rocks they cut through". Structures in rocks are younger than rock layers they cut through.
A fault or joint will only pass through a rock that has been formed before it occurred. Subsequent rocks will be younger than the fault.
