Question

1. provide the name for the following compounds: (note: in compounds where charges must be balanced, you are required to show all of your work - i.e., bubble method!) a) cas compound name: __________ b) p₂o₅ compound name: ________ c) cr(oh)₃ compound name: ________ d) sc₂se₃ compound name: ________ e) ca(clo₃)₂ compound name: __________

Explanation:

Step1: Identify cation and anion for CaS

Calcium (Ca) is a metal with a +2 charge and sulfur (S) is a non - metal with a - 2 charge. The compound is named calcium sulfide.

Step2: Identify elements in P₂O₅

Phosphorus (P) and oxygen (O). It is a covalent compound, named diphosphorus pentoxide.

Step3: Identify cation and anion in Cr(OH)₃

Chromium (Cr) is the cation and hydroxide (OH⁻) is the anion. Chromium has a +3 charge here, so it is named chromium(III) hydroxide.

Step4: Identify cation and anion in Sc₂Se₃

Scandium (Sc) is the cation with a +3 charge and selenium (Se) is the anion with a - 2 charge. It is named scandium selenide.

Step5: Identify cation and anion in Ca(ClO₃)₂

Calcium (Ca) is the cation and chlorate (ClO₃⁻) is the anion. It is named calcium chlorate.

Answer:

a) Calcium sulfide
b) Diphosphorus pentoxide
c) Chromium(III) hydroxide
d) Scandium selenide
e) Calcium chlorate
