Answer:
Chemical formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's chemical formula cannot be reduced any more, then the empirical formula is the same as the chemical formula. Combustion analysis can determine the empirical formula of a compound, but cannot determine the chemical formula (other techniques can though). Once known, the chemical formula can be calculated from the empirical formula.
Explanation:
Yes, carbon dioxide should be considered a pollutant. The emissions from fossil fuels have set the natural cycle of CO2 off kilter. With the destruction of massive amounts of forests and natural habitats, the population of plants is going down, but the emissions of man-made CO2 are going up.
They are called <span>Frequency-modulated</span>
Because electrons are the only piece of the atom that is outside of the nucleus. the protons and neutrons are inside the nucleus.
then also the electrons itself have the charge to begin with
