Se mezclan 100 ml de CH3COOH al 0,05 F con 115 ml de una solución de CH3COONa al 0,07 F (Ka = 1,8x10– 5). Determine: añadir: a) 20mldeHClal0,23F
b) 15 ml de NaOH al 0,115 F
c) 25mldeNH3 al0,02F
d) Cuál es la variación de pH al añadir 22 ml de CH3COOH al 0,2 F

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
