Titration practice
use the following balanced equations for your reference:
hci + naoh --> nacl + h20
2koh + h2so4 --> 2h20+ k2so4
5 points
if it takes 2.0 l of 5.0 m naoh to neutralize 5.0 of an hcl solution, what is the concentration of the hci?
o 20m
-20 m
5.0m
20 m

2 M

Explanation:

If it takes 2.0 L of 5.0 M NaOH to neutralize 5.0 of an HCl solution, the concentration of the HCI is 2 M.

2 Liters of 5 molars = 2 x 5 =  10 moles

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
