B
Acid rain is a dilute solution of acids that dissolve
the calcium carbonate in limestone statues.
Concentrated acids can dissolve a large piece of
limestone in a few days. Statue breakdown due to
acid rain can take decades, but statues with
intricate carvings break down more quickly.
Explain these observations in terms of reaction
rates.

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion
