Silver perchlorate - 3. Stannic chloride - 9. Sulfurous acid - 4. Copper(I) cyanide - 5. Mercury(II) oxide - 6. Calcium hydrogen phosphate - 10. Tetraphosphorus decasulfide - 11. Perbromic acid - 12. Rubidium hydroxide -

- recall the rules for naming ionic and molecular compounds that we learned; do not invent names: - do not include "di" in the names of elements that exist as diatomic molecules: Cl2(g) is not "dichlorine", it is a "chlorine gas": - do not confuse compounds and ions: SO3 is not sulfite, but sulfur trioxide (sulfite is SO32), * A “+" sign on the left of the arrow is interpreted "... reacts with * For each substance include its state of matter (using words, not symbols). * Your sentences should include verbs (remember, you are telling a story). MnO2 Example. 2 H2O2(aq) 2 H2O(1) + O2(g) hydrogen peroxide Hydrogen peroxide in a water solution decomposes in the presence of manganese(IV) oxide. As the result of the reaction, liquid water on oxygen gas are generated. Another example. Mg(s) + CuCl2(aq) → MgCl2(aq) + Cu(s) Solid magnesium (you can also say "metallic magnesium", since it is a metal in its elementa form) reacts with copper(II) chloride dissolved in water. The reaction produces…
