Answer
(a) sodium oxide
(b) sodium sulfide
(c) sodium sulfate
(d) sodium nitrate
(e) sodium nitrite
Work Step by Step
(a) sodium oxide
This compound is a simple binary ionic compound. To name this compound, we name the first compound using its full name (sodium). Then we add the second element (oxygen), changing its ending to $-ide$.
(b) sodium sulfide
This compound is a simple binary ionic compound. To name this compound, we name the first compound using its full name (sodium). Then we add the second element (sulfur), changing its ending to $-ide$.
(c) sodium sulfate
This compound is a compound containing an oxoanion. To name this compound, we name the first compound using its full name (sodium). Then we add the second portion, which is the oxoanion sulfate. There is no need to change the ending here.
(d) sodium nitrate
This compound is a compound containing an oxoanion. To name this compound, we name the first compound using its full name (sodium). Then we add the second portion, which is the oxoanion nitrate. There is no need to change the ending here.
(e) sodium nitrite
This compound is a compound containing an oxoanion. To name this compound, we name the first compound using its full name (sodium). Then we add the second portion, which is the oxoanion nitrite. There is no need to change the ending here.
