0.32 L of HNO3 is titrated to equivalence using 0.12 L of 0.2 M NqOH. What is the concentration of the HNO3

Explanation:

Hello!

In this case, since the reaction between NaOH and HNO3 is:

Whereas there is a 1:1 mole ratio between the acid and base, thus, we can write:

In such a way, solving for the concentration of the acid, HNO3, we obtain:

Therefore, by plugging in we obtain:

Best regards!

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
