<span>The atomic number of an element indicates only how many protons are in that specific element. The atomic number of sulfur is 16, so it means that in one sulfur atom, there are 16 protons. The number of protons is also equal to the number of electrons in any given atom, so this number also indicates that there are 16 electrons in a sulfur atom.</span>

The statement that is true for most chemical reactions is that A. An energy change occurs during the breaking and forming of chemical bonds. As the reactants react ultimately producing products the atoms of the respective elements within the compounds if present will break and reform ultimately to produce the products, during this change energy transformation from chemical bond formation and breakage occurs, and allows one to determine whether or not a reaction releases energy or needs a substantial amount of energy based on the energy content of the reactants and products.
Answer:
I believe the correct answer is D.
Explanation:
You are breathing in dinitrogen and dioxygen. You exhale dinitrogen and carbon dioxide. And the atmosphere contains traces of other gases. You drink water. You have a wash with water, and soap. You eat carbohydrates and proteins. You ride to work on a vehicle powered by hydrocarbons, which spits out carbon dioxide exhaust fumes, and also some nitrogen oxides. And so your exposure to chemicals is pervasive, and unavoidable.
