Answer:
Igneous rock
Explanation:
The rock held by Florian is already a metamorphic rock. On further subjection for heat and pressure, the rock will melt to become igneous rocks.
- A banded rock is termed a gneiss
- In such a rock body, areas concentrating dark minerals and light minerals alternates to form the distinct domains.
- This in turn results from a very high grade metamorphic event.
- In retrospect, if this rock body is further heated, a melt or magma form which is the material by which igneous rocks are derived from.
Answer:
Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.
Explanation:
Relative atomic mass : C= 12 and H=1
Percentage of Carbon Hexane (C6H14)
Percentage of Carbon = 83.7 percent
6(12) x 6(12) +14(1) x 100 percent= 83.7 percent
Percentage of Carbon Hexene = 85.7 percent
Answer:
The process of combining the smaller nuclei to make larger one is called fusion.
Fusion occurs on the sun.
Explanation:
Fusion:
It is the process in which smaller nuclei combine to form the larger nuclei.
Fusion process also occur in the sun.
It is known as proton-proton fusion. In this proton-proton fusion, the atoms of hydrogen fused together and form helium-4. This is accomplished through several steps hydrogen atoms combine to form deuterium.
This deuterium atom fused with proton and form helium- 3.
Gamma rays are also produced in this reaction.
This helium-3 combine with another helium-3 and form helium-4 atom and two protons.
It will react by being a chemical change because something new is formed
