name the following compounds and tell what type of compound they are (binary ionic. ternary ionic, or binary molecular)
a)FeBr3
b)CBr4
c)Na2Cr2O7
Little late to the party lol
FeBr3 - Iron(III)bromide
CBr4 - Carbon Tetrabromide
Na2Cr2O7 - Sodium dichromate
FeBr3 - Iron(III)bromide - binary ionic
CBr4 - Carbon Tetrabromide - binary molecular
Na2Cr2O7 - Sodium dichromate - ternary ionic
To name and determine the type of compound for each of the given compounds, you need to understand the rules and conventions used in chemical nomenclature.
a) FeBr3:
To name this compound, we first need to identify the elements involved and their oxidation states. Fe represents the symbol for iron, and Br represents bromine. Iron (Fe) has a variable oxidation state, which is indicated by the Roman numeral following the name. In this case, iron has a +3 oxidation state, indicated by the Roman numeral III. Bromine (Br) has a fixed oxidation state of -1 in this compound.
Using these details, we can name the compound as iron(III) bromide. FeBr3 is a binary ionic compound since it consists of a metal (Fe) and a non-metal (Br).
b) CBr4:
For this compound, we have carbon (C) and bromine (Br). Carbon is a non-metal, so it will most likely form a binary molecular compound. The prefix "tetra" indicates the number of bromine atoms.
Based on this information, we can name CBr4 as carbon tetrabromide. CBr4 is a binary molecular compound since it consists of two non-metals (C and Br).
c) Na2Cr2O7:
In this compound, we have sodium (Na), chromium (Cr), and oxygen (O). Sodium is an alkali metal, which forms ions with a charge of +1. Chromium has variable oxidation states, and in this compound, it has a +6 oxidation state. Oxygen, as usual, has an oxidation state of -2.
Considering this information, we can name Na2Cr2O7 as sodium dichromate. This compound is a ternary ionic compound since it consists of a metal (Na) and polyatomic ions (Cr2O7).
Remember, to correctly identify and name compounds, it is essential to have an understanding of the periodic table, oxidation states, and the rules of nomenclature.
