Which statement best describes the social status of women in ancient Egypt? Women were viewed as the lowest social class. Women
Usimov [2.4K]

Answer:

In ancient Egypt, women were given many of the same rights as men.

Explanation:

The women in ancient Egypt were in no way seen as the lowest social class, so this statement is not correct.

The women were allowed by law to do pretty much everything as the men, so their status was not dependent on their husbands, so it is not a correct statement.

The women were equal in front of law in ancient Egypt, as well as being able to do the same things as men, so this statement is correct.

Women did not have the same status as their fathers, so this is not a correct statement.

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react w
sammy [17]

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

Brrunno [24]
Do you mean "why"?

They are the main source for all living organisms because they provide energy, relatively short term, for any creature that consumes them.
