Is Cr2O3 an ionic or molecular compound?
Cr2O3 is ionic.
What is the oxidation number for Cr in Cr2O3?
+6 for Cr, -2 for each O in Cr2O72-oxidation number for oxygen is -2 so 7 of them makes -14 in total but the compound has an overall charge of 2- so therefore +12 is required. As there are two chromium then the oxidation number for each one is +6
What is the oxidation number of IF?
oxidation number of I is -1. oxidation number of F is +1.
What is the oxidation number of zns?
Zn has oxidation number +2; S has oxidation number -2
What is the oxidation number of H2O2?
The oxidation number for H is +1, and the oxidation number for O is -1.
What is the correct name for compound Cr2O3?
For ionic compounds such as the one mentioned above, naming them is relatively easy. As we all know, an ionic compound consists of a metal ion(which is usually positive) and a negative ion. Hence, the names for metallic compounds are always in the following format: Name of metal + Name of negative ion However, do take note that for transition metals, the oxidation state has to be included. This is because transition metals have multiple oxidation states. The oxidation state of the metal is presented by: Metal (oxidation number). For example, rust is Iron (III) oxide. Cr2O3 is hence named chromium (III) oxide.
Is Cr2O3 an ionic or molecular compound?
Cr2O3 is ionic.
Whah forms of chromium is there?
I'm no chemist but you have CrO2, CrO3, Cr2O3, and Cr3O4...different oxidation levels because of its polyatomic ion's. IE. baking soda.
