Answer:
d. 20 protons and 22 neutrons
Answer :
- <u>Part A :</u> The given unbalanced redox reaction is,
Now we have to balance the given redox reaction in acidic medium by half reaction method.
1st half reaction :
2nd half reaction :
For net balanced reaction, 1st half reaction is multiplying by 8 and 2nd half reaction is multiplying by 5
The net balanced redox reaction is,
- <u>Part B :</u> The given unbalanced redox reaction is,
Now we have to balance the given redox reaction in basic medium by half reaction method.
1st half reaction :
2nd half reaction :
For net balanced reaction, 1st half reaction is multiplying by 2.
The net balanced redox reaction is,
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:
This answer is based off of the fact that my own house is made of bricks.
Bricks like anything will weather over time when exposed to these conditions. I would not say the sun effects the bricks too much due to them being heat reflective. As long as the bricks have been laid down correctly, the wind should not effect it. Weather will cause the most damage for sure
