<span>I bet this is the notation used in nuclear reactions. The superscript represents the mass number while the subscript represents the atomic number of the element X. So, we find the element with an atomic number of 12. That would be Magnesium or Mg.</span>
Answer:
The dam disrupts the river wildlife and ecosystem.
Explanation:
Though it is believed that using the dam as a power generation or hydroelectric power supply generates no greenhouse gases, it, however, has many disadvantages which make it deemed not suitable or sustainable for use in the contemporary time.
Majorly, the top reason why more hydroelectric dams are not built is that "the dam disrupts the river wildlife and ecosystem."
Also, it affects the water quality and other use of water for humans such as recreational use.
There is also a possible chance of dams producing methane; a greenhouse gas through the organic materials in the water that is rotting.
It is a <u><em>chemical compound</em></u> formed with a metal (mainly positive cations) with oxygen.
It is formed through the air as they react in the air together.
They are also BASES - ALKALINE (so neutralise acids)
C6H12O6 + O2 = CO2 + H2O
Balanced Equation:
1 = C6H12O6
6 = O2
6 = CO2
6 = H2O
The nearest dollar would be 1 dollar because 3 is closer to 1 than to 5 or to 10 so therefor you would be rounding down.
