Answer:
c) Normal
Explanation:
Reflection is a phenomenon typical of light wave; it occurs when a ray of light hits the interface between two mediums, and bounces off back into the original medium, at a certain angle.
The direction of the reflected ray is determined by the law of reflection, which states that:
1) The incident ray and the reflected ray, together with the normal to the interface (the perpendicular to the interface), all lie within the same plane
2) The angle of incidence is equal to the angle of reflection:

where
is measured as the angle between the incident ray and the normal to the interface
is measured as the angle between the reflected ray and the normal to the interface
D. Since it's atomic # is 14 it has 14 electrons and it has 4 valance electrons because it is 4 over.
The correct answer to this question is carbon dioxide. A cake rises as it bakes because a chemical change causes carbon dioxide to be produced. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
Simply look at the periodic table and fill in what you know based on the table
The number of protons = atomic number
The number of electrons, Which is the same as the atomic number for atoms.
The number of valence electrons that is given by the group that the element is in, the top number of each column in the periodic table.
Answer:
Charlemagne has been called the "Father of Europe" (Pater Europae), as he united most of Western Europe for the first time since the classical era of the Roman Empire and united parts of Europe that had never been under Frankish or Roman rule.
