Answer:

4Fe + 3O₂ → 2Fe₂O₃

General Formulas and Concepts:

Chemistry - Reactions

Balancing Reactions

Explanation:

Step 1: Define

RxN: Fe + O₂ → Fe₂O₃

Step 2: Balance

We need to balance both Fe and O.

LCM of 2 and 3 is 6:

Fe + 3O₂ → 2Fe₂O₃

We now need the same amount of Fe on both sides:

4Fe + 3O₂ → 2Fe₂O₃

Which scientist explained why binary stars change colors

Vinvika [58]

Answer:

This is because of scintillation ("Twinkling") as the light passes through the atmosphere of the Earth. As the air moves in and out, the starlight is refracted, often different colors in different directions. Because of this "chromatic abberation," stars can appear to change colors when they are twinkling strongly.

How is energy transferred during the water cycle

likoan [24]

Answer: Option (d) is the correct answer.

Explanation:

In water cycle, water from clouds fall in the form of rain, snow etc. This water travels through the surface of mountains and passes through rivers, oceans etc and gets evaporated due to heat from Sun.

When water evaporates then it absorbs energy in the form of heat from Sun and when water condenses then heat is released.

Therefore, water gains energy during evaporation and releases it during condensation.
