23.9 cm^3 of barium hydroxide solution required exactly 25.0^3 of 0.0871 mol dm^3 nitric acid for complete neutralization. Calculate the molar concentration of the barium hydroxide solution by carrying out the following steps:

a) Calculate the number of moles of nitric acid used in this titration
b) Calculate the number of moles barium hydroxide in 23.9 cm^3 of solution using the equation to provide a link from a)
c) Now calculate the molar concentration of the barium hydroxide

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

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
