Answer:
option D= Gold (I) nitride
Explanation:
The name of the given compound is gold(I) nitride.
Molar mass can be determine by following way:
molar mass Au3N = (molar mass of gold × 3) + (molar mass of nitrogen)
molar mass Au3N = (196.97 × 3 ) + ( 14 )
molar mass of Au3N = 590.91 g/mol + 14 g/mol
molar mass of Au3N = 604.91 g/mol
The nitrogen has valency of -3 so three Au(+1) will require while the valency of Au is (1+) one nitrogen will require to make the compound overall neutral.
Au3N
3(1+) + (-3) = 0
+3 - 3 = 0
0 = 0
The overall charge is 0, the compound will be neutral.
The dissolution of borax in water is a temperature dependent reaction. With the higher temperature, the salt dissolve quickly.
<h3>What is borax?</h3>
Borax is the hydrate salt of boric acid. It is white and widely used in cleaning and in laundry detergent.
Borax is a salt that will dissolve in water at almost any temperature, with the exception of steam and ice.
However, as with any salt, the higher the temperature, the faster the salt dissolves, so speed is dependent on temperature. It will dissolve in cold water, but it will take longer.
Thus, the dissolution of borax in water is a temperature dependent reaction.
