Hydrochloric acid and sodium hydroxide neutralise each other and the pH resulting solution will be 7.
Honey is solution, it can't be taken broken apart (can't separate the ingredients)
Hope this helps!! :D
Answer:
- Chlorine
- Bromine
- Iodine
Explanation:
All three of these elements fall in group 7 of the periodic table and are called Halogens. Chlorine is the most reactive of these elements because it comes before the other two in the table then followed by Bromine and then Iodine.
Reactivity decreases in the group 7 elements as one moves to the latter elements due to the increase in shells surrounding the nucleus.
This is because reactivity happens as the protons in the nucleus attract electrons but when more shells are piled on, the strength of this attraction decreases as the distance increases such that they will not be as reactive anymore.
The compound originally contained KNO₃ solution.
Explanation:
When a mixture which contains either Pb(NO₃)₂ or KNO₃ is added with NaCl solution, no reaction takes place. This confirms the presence of KNO₃ in the solution.
The reason behind the above activity can be attributed to the lower placement of Na (sodium) in reactivity charge than potassium (K). Hence, it cannot displace Potassium (K) from the aqueous KNO₃ solution. Whereas the NaCl reacts with Pb(NO₃)₂ to produce white insoluble precipitate of PbCl₂. This confirms the presence of KNO₃ in solution.
Answer:- 2,1
Explanations:- Water is and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.
Hence, the answer is 2,1.
