Chromium has a positive charge (it's a multivalent metal with multiple positive charges)
Carbonate has a negative charge (-2)
Chromium would be the cation, and carbonate would be the anion.

<span>A. smog
B. Use a large amount of water
C. increased temperatures
D. poisoning wildlife
The correct answer is D) poising wildlife. Burning fossil fuels and pesticide from farming have the effect of releasing toxic elements in nature, thus the consequences of poisoning wildlife. The fossil fuels released CO2 and other particulates that threats the respiration system of most animals, while the pesticide that animals ingest or breath can have different effects on the wildlife, depending on the type of pesticide.

Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
