Answer:
Refraction is the bending of a wave when it enters a medium where its speed is different, like going from the air (gas) to a glass of water (liquid). Absorption is when light energy penetrates an object. Typically this energy is then converted to heat.
Answer:
Explanation:
Here, we want to write the chemical reaction
step 1:
we start by writing the reaction between iron and oxygen
We have this as:

step 2:
Now, we want to predict the product as follows:

step 3:
We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:
