Answer:
Scientists use models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.
Hope this helps :)
Answer:
Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.
Quartz, or silicon dioxide (SiO2), is one of the most abundant minerals on Earth. The diagram shows the atomic arrangement of quartz.
Based on the diagram, which statement best describes the atomic arrangement of quartz?
Group of answer choices
An extended structure that is made of repeating patterns of atoms.
A repeating pattern of small molecules that can move freely past each other
Many different kinds of molecules tha combine to form an extended structure.
Many different kinds of atoms that can move freely past each other.
Based on the atomic arrangement of quartz, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.
What is quartz?Quartz is a hard crystalline mineral found within the Earth's crust and which is composed mainly of the mineral silica. Silica is mostly silicon(iv) oxide.
Quartz is colourless and its crystalline structure is of a hexagonal prism. The atoms are arranged in a regular repeating grid to form the hexagonal crystal.
Therefore, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.
