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:
proton: positive
electron: negative
neutron: neutral
Looks like you already have it.
The volume of base that is actually needed is 24.5 ml of base.
Titration is a chemical technique which is used in chemistry to find out the concentration of an unknown solution. A solution of known concentration is usually used to determine the concentration of the unknown solution. The known solution is usually added to a specific quantity of the unknown solution until the reaction is complete. An indicator is typically added to the unknown solution and the reaction is deem to be completed when there is a color change in the unknown solution.
Thus, the volume of the base that is required to reach the color end point is actually the base volume that is needed for the reaction.
Explanation:
The structure and operation of the complex societies of the developed world are completely dependent on countless applications of technology, as we can observe in our daily lives. But what we may be less conscious of is that the evolution of society - what it will be tomorrow - is also highly dependent on our development and application of technology; to a large extent our society is what it is today as a result of the technology we chose to apply in the past. Engineers play a major role in the development and application of technology, and so have a responsibility for the evolution of society. It is the nature of that responsibility that is the subject of this paper, and it is suggested that it is mainly in providing the information society requires in order to make its decisions.
