295 ml of a 1.00 m ammonium
chloride (nh4ci) solution is diluted
with 2.25 l of water.
what is the new concentration in
molarity?

0.116 M.

Explanation:

The new  molarity is 295/ (2250 + 295) M

= 0.116 M.

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
