A chemical element is a substance that is made up of only one kind atom.
Experiments suggest that organic molecules could have been synthesized in the atmosphere of early Earth and rained down into the oceans. RNA and DNA molecules — the genetic material for all life — are just long chains of simple nucleotides. Replicating molecules evolved and began to undergo natural selection.
Answer:
B . Changing the material that the fluids container is made of
Explanation:
Changing the material of the container does not affect the pressure in a container whereas increasing the volume, changing the weight of the fluid, and heating/cooling the fluid will all change the pressure.
Answer:
Explanation:
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.
