Answer:
Model B
Explanation:
Model A shows that light has been reflected, whereas Model B shows the light has been refracted. Light will be refracted as the light enters a more dense medium (glass), from a less dense medium (air).
This website has a really useful, thorough explanation for why this occurs:

Answer :
The balanced chemical reaction is,
From this balanced chemical reaction, we conclude that
2 moles of iron oxide react with the 3 moles of carbon to give 4 moles of iron and 3 moles of carbon dioxide.
Therefore, the valid mole ratio from the balanced chemical reaction is,
Answer:
electrons
Explanation:
When elements combine to form compounds, chemical bonds form between the atoms. Bonds form when atoms share or exchange electrons in a way that gives each atom a complete outer shell.
For example:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and have complete octet.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive. Both have complete octet.
Metals are on the left side of the table and nonmetals are on the left with metalloids between them. And the noble gases are all in group 18 of the periodic table.
