I would say C. Permable
Google def.(of a material or membrane) allowing liquids or gases to pass through it.
"a frog's skin is permeable to water
Porous- (of a rock or other material) having minute spaces or holes through which liquid or air may pass
When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
Below are the steps to get the answers:
<span>1.) write out the balance equation
3NaOh+H3PO4->Na3PO4+3H2O
2.) You are given everything needed to calculate
q=heat transfer=2.2*10^2, H3PO4 moles= 1.5*10^-3, NaOH moles=5.0*10^-3
3.) equation is deltaHneutraliztion=q/Moles of limiting reagent
H3PO4 is limiting reagent because lowest moles, and is used up first
4.) Now plug in variables
DeltaH=2.2*10^2(1.5*10^3)= 146.67kj/mole
Notice we had to convert J to kj, </span>
Chemical reactions that release energy will not occur without a source of energy. So the answer is release.
Ammonium hydroxide aka ammonia is a colorless gas that smells awful.... ammonia contains nitrogen and hydrogen.... and also ammonia is used as a lifting gas, which means it cans be used to lift hot air balloons.... lol that was just a weird fact..... but have an amazing day/night and god bless u!
