Answer:
The rock cycle describes how rocks change as a result of natural processes. The rock cycle forms new rocks using the crystallization, erosion and compaction processes. This makes the correct answer: D: all of the above. Igneous rocks for example are rocks formed from the crystallization( formation of rock crystals in cooling magma) of a liquid. Sedimentary rocks are formed by erosion. However, in order to form a sedimentary rock, the accumulated sediment must become compacted and cemented together.
The oxidation number if eah of the elements is as follows;
- Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
- Oxidation number if hydrogen is +1 on both sides
- The oxidation number of oxygen is -2 on both sides
- The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
<h3>What is a redox reaction?</h3>
A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.
Let us now consider the oxidation number of each element from left to right;
- Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
- Oxidation number if hydrogen is +1 on both sides
- The oxidation number of oxygen is -2 on both sides
- The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
