The answer is C . when the light slows down
Potassium, Barium, and Copper because they are metals, and most metals tend to lose electrons when forming an ion.
Answer:

Explanation:
Hello there!
In this case, since these problems about formulas, firstly require the determination of the empirical formula, assuming that the given percentages are masses, we can calculate the moles and mole ratio of oxygen to iron as shown below:

In such a way, by rounding to the first whole number we multiply by 8 and divide by 5 to obtain:

Whose molar mass is 159.69 g/mol and the mole ratio of the molecular to the empirical formula is:
479.1/159.69=3
Therefore, the molecular formulais:

Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. ... Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
hopefully that answered your question. brainliest would be appreciated. have a awesome day!
