Answer:2097.5998675091255
Explanation:
2Na + 2H2O ——> 2 NaOH + H2
Molar mass NaOH ( sodium hydroxide) = 40.0 g/mol
Number of moles:
n = mass / molar mass
n = 10.0 / 40.0
n = 0.25 moles
Volume = 2.0 L
Molarity = number of moles / volume in liters
M = 0.25 / 2.0
M = 0.125 M

Answer:
likely ionic
Explanation:
The bond between , Sodium and Bromine , in sodium bromide salt , is ionic in nature .
Since ,
The difference in the electronegativity of the two atom is high .
According to Pauling scale ,
The Electronegativity of Bromine = 2.96
The Electronegativity of sodium = 0.93
Hence ,
The Difference in electronegativity = ( 2.96 - 0.93 ) = 2.03
Hence ,
The electronegativity difference value is more than 1.8 ,
Therefore,
The bond is ionic in nature .
