The k+ ion has an electron structure that is identical to which inert gas?

1 answer:

8 0

You should understand the concept that ions occur because they want to achieve stability. Among the elements in the periodic table, only Group 8 or the noble gases are stable. Hence, other elements must gain or lose electrons so that they can achieve the same configuration of the nearest noble gas to them. For potassium, the nearest one is Argon.

Explain whether or not you expect the chaparral biome to be sensitive to the loss of a single species.

aleksley [76]

Answer:

See the answer below

Explanation:

The chaparral biome is a temperate biome with a characteristic high temperature and dryness during summer and mild rainy winters and springs. The biome can be found in relatively small amounts in the major continents of the world with its rich plant and animal diversity who have successfully adapted to the conditions of the biome.

Due to the high biodiversity of the chaparral biome, one would expect it to be resilient to the loss of a single species. The more the biodiversity of a biome or community, the more resilient such biome or community would be to the loss of species and lower the biodiversity, the more sensitive the community would be to the loss of species.

fish give off the compound ammonia which has a pH above 7 to which class of compounds does ammonia belong

jasenka [17]

Answer:
The compound ammonia given by fish is alkaline

Explanation:
We can classify elements/compounds based on their pH values into three types:
acids: these are compounds having pH value lower than 7
neutral: these are compounds having pH value equal to 7
alkalies: these are compounds having pH values higher than 7

This is shown in the attached image

We are given that the pH of the compound ammonia generated by the fish is above 7.
According to the above explanation, compound ammonia would be an alkaline compound.

Hope this helps :)
