When looking down the groups the elements have an equal number of electrons in the outer shell. This means they react in a similar way making it easier for scientists to use.
Answer:
1. Atmosphere ⇒ Ocean ⇒ Marine Plants ⇒ Sediments ⇒ Natural Gas
.
2. Atmosphere ⇒ Land Plants ⇒ Natural Gas.
Explanation:
Hello,
In this case, it is widely known there are two ways in which natural gas is formed:
1. Atmosphere ⇒ Ocean ⇒ Marine Plants ⇒ Sediments ⇒ Natural Gas
.
In this one, the carbon dioxide in the atmosphere, is able to get through the ocean and in touch with marine plants which have the capacity to undergo photosynthesis and yield sugars which are subsequently fixated in the soil as sediments containing fossil fuels, coal and/or natural gas.
2. Atmosphere ⇒ Land Plants ⇒ Natural Gas.
In this one, the carbon dioxido also in the atmosphere is captured by the land plants which use it to undergo photosynthesis and subsequently fix it into the underground as fossil fuels, coal and/or natural gas as well.
Best regards.
Answer:
Explanation:
The equation is not correctly written, so let's start with that.
4Al + 3O2 ====> 2Al2O3?
Totally correct, including the balance numbers, would be
4moles aluminum + 3 moles Oxygen ===> 2 moles of Aluminum Oxide
Anything else is incomplete.
Your question has been heard loud and clear.
Specific applications of mass spectrometry include drug testing and discovery, food contamination detection, pesticide residue analysis, isotope ratio determination, protein identification, and carbon dating.
Thank you
Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!
