it is called an element sir.
I believe so because the oxygen goes from 0 to 2- and magnesium goes to 2+ so the oxygen is being reduced and the magnesium is begin oxidized.
Answer:
D: Decomposition Reaction
Explanation:
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
The general form of a decomposition reaction is: AB -> A+B.
You just split the nonmetals into a molecule depending on the element.
But they are rules though when doing this reaction. If a element is a diatomic molecule, then you would write a 2 in the subscript.
Diatomic molecules contain two atoms that are chemically bonded
<h3>The 7 diatomic elements are: </h3><h3>H: Hydrogen H2</h3><h3>N: Nitrogen N2</h3><h3>F: Fluorine F2</h3><h3>O: Oxygen O2</h3><h3>I: Iodine I2</h3><h3>C: Carbon C2</h3><h3>B: Bromine B2</h3>
Now let us go back to this problem: 2H2O -> 2H2 + O2
So water or 2H2O split into 2H2 and O2 because hydrogen and oxygen are diatomic elements.
That is how you write the product of a decomposition reaction.
Hope it helped!
Answer:
Explanation:
Hello,
In this case, considering that the density is defined in terms of mass and volume as follows:
Due to the fact that 100 tons of water were displaced, whose value in grams is:
Thus the displaced volume in cubic meters was:
Regards.
Well according to study.com," Subsidence can lead to the formation of a sedimentary rock because it forms basins or depressions where deposition can occur..." Here's the link for more info:
