Well, Carbon has 4 Valence Electrons. I'm sure you know this, but valance electrons allow electrons to covalently bond with one another. The elements, when sharing the electrons, want to have 8 valance electrons. So carbon has 4 valance electrons so it can bond with itself, or another say 4 hydrogen [becuase hydrogen can live with 2 valance electrons]. Hope this helps. Remember: Electrons <3 8 valance electron bonds Carbon's 4 + Carbon's 4= 8 true love at first bond! OR Carbon's 4+ Hydrogen's 1 [x4] = 8 hope this help
Answer:
Renewable resources cannot disappear, non-renewables will not last forever. Non-renewable energy sources, such as coal, nuclear power, oil, and natural gas, are available in limited quantities.
Explanation:
A renewable resource, for example, is solar energy. It is renewable because the sun can never disappear.
Non-renewable resources take a long time to replenish, if this ever happens. Renewable resources naturally recharge over a relatively short period. Non-renewable resources are natural resources that exist in fixed quantities and can be utilized. Examples include fossil fuels such as oil, coal and natural gas.
Both types of resources have a big influence on biodiversity and people shouldn't be spending them without limit.
Answer:
rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms.
Explanation:
carbo is found in these places for example:
Answer:
Uracil
Explanation:
DNA only uses Thymine so that leaves Uracil for RNA because all of the other bases are used for both.
