Answer:
The boiling point of NaBr is higher than that of Na2S
Explanation:
Bromine has higher electronegativity as compared to the sulphur. The ionic strength of the bond formed with Sodium is higher in the NaBr compound. The higher the ionic bond strength the higher will be the boiling point
Also the size of bromine is large as compared to that of sulphur. Large molecules consists of more electron and hence they create der Waals attractive forces due to which the boiling point of compound increases.
Hence, the boiling point of NaBr is higher than that of Na2S
Answer:
first second and last is mechanical while third and fourth is chemical
Answer:100c
Explanation:
water boils at 100c the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure
El sonido es una onda que se crea por vibración y se propaga a través de un medio de un punto a otro. De modo que es basicamente una onda mecánica longitudinal.
Es una onda mecánica pues necesita un medio para propagarse,
