Answer:
Texture Gradient
Explanation:
Texture Gradient -
It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .
The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .
The three types of texture gradient are-
- perspective ,
- density and
- distortion of texture elements .
Hence , from the given information of the question ,
The correct answer is texture gradient .
There are 7.0 x 10^22 C2H5OH molecules in the sample.
Ethanol (also referred to as ethyl alcohol, grain alcohol, consuming alcohol, or actually alcohol) is an organic chemical compound. It is simple alcohol with the chemical system C2H6O. Its method can be also written as CH3−CH2−OH or C2H5OH (an ethyl team linked to a hydroxyl group) and is regularly abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with an attribute wine-like odor and pungent taste. It is a psychoactive drug, a leisure drug, and an energetic ingredient in alcoholic drinks.

Answer:
A. The mass of the solid formed is 0.5g
Explanation:
An experimental observation can either be QUANTITATIVE OR QUALITATIVE. A quantitative observation is that which uses numerical representation to describe collected data. Examples are height, volume, mass etc.
According to this question, a student performs an experiment in which two liquids were mixed to result in the formation of a WHITE SOLID in the solution. Based on the options provided, the quantitative observation that could be derived from the result of this experiment is that "The mass of the solid formed is 0.5g".
Note that, the option that states that: volume of 10 mL of each of the liquid components was used in the experiment is also a qualitative observation but it is not derived from the RESULT of the experiment.
Elements and compounds. This is because in solutions and mixtures the substances are not bonded to each other or pure, you can separate and purify substances in solutions and mixtures (via techniques such as distillation, filtering) but you cannot separate compounds as they are bonded together.
