I though of another idea. What will be if three sodium is bonded to nitrogen atom? Assume the geometry is the same, is the new molecule is more reactive than the ammonia molecule?

Good explanation!

Only hydronium ion and hydrogen ion are acidic ion?

Ya. I only know hydronium ion and hydrogen ion is acidic and corrode other ? which ions else corrode substance?

Oh I get a new acid in my dictionary-p Is calcium carbonate a weak alkali?

Is that a good hobby to think more about something? And where to get more things to make hypothesis?

Thank you. Before your clarifying, my mind was that the break gave a ammonia molecule and one hydrogen ion. I was wrong! Is that possible? Only one charged particles stay in room? I think the energy to break to give the hydrogen ion out from that molecule is very large, right?

Does a physist have no knowledge about chemistry? Does a biologist have no knowledge on the chemistry? What's the basic of science? Observation, hypothesis? Or a smart brain>?

The break produce hydrogen gas?

Is economics a kind of science? I currently study economics, so far , want to be shared with some ideas .

I always think of my early retirement after I had earned some money. I am too nervous to handle those challenge and stress. Maybe I will change my mind but just want to say here.:

Is it the deep meaning of a more reactive displace a less reactive?

I think I could help you. I was puzzled in this in my form 3 year. Although I was not taught to learn that, I found it myself:P Polyatomic ion consists of covalent bonds. Just imagine the ammonia molecule, NH3. If it is given one H one , it should be NH4 , right? But it is more stable when it lose one electron . Therefore, it become NH4+. Ya, I nearly forgot to tell you something which was mentioned by my buddies before. They are so professional and this web site are professional too, even is the best of the forums. Sometimes, they may think the thing " coordinate covalent" you have learnt. I am not very powerful so I know the situation you are facing to. Coordinate covalent bond is a covalent bond. Take Ozone,O3 , as example.( please find the structure yourself) One oxygen atom shares one pair to obtain another pair with an oxygen atom. Then the second oxygen atom gives one pair to share with the thrid one, but the third one doesn't give any to share. Coordinate covalent bond occurs.

i think race to space wastes a lot of natural resources. I vote the bad one

Sorry I don't know , I only know water plant doesn't have stomata and no upper epidermis. Hope it would help.

How about the bonding strength in a particular molecule? such as potassium fluoride, stronger or less stronger than francium chloride?

That sound pretty good. I better start with drawing a dog first. My drawing is extremely bad as my english composition.

Is the reactivity directly depended on the electronegativity ?

That's means chemical potential? How to combine the ideal law with the attractions to show ? Sorry, the salt ions change to big molecule. OK?

I want to have a more clear further concept for the osmosis, can anyone help me? When do the net movement become equilibrium? Same pressure, same water potential? Or same concentration ( Probably wrong, right?)? My teacher used a dialysis tubing containing pure water, why isn't the water coming out at once after it is taken out from the pure water solution? May you refer my ugly or beautiful drawing first? In region A , there is a lot of mobile ions and water molecules. In region B, there is a lot of water molecules and ions are absent. A selectively membrane separate them. 1.Why the rate of the water molecules flow from high water potential solution is higher than the rate of water molecules flow from the salt solution? Isn't the density of the salt solution is higher than the density of the water solution and has a greater pressure to push the water molecules(B) back to B? 2. Is the external pressure concerned on the reaction force only? Not describing the pressure by the B ? Really appreciate anyone who help me.

Ya! I am in this situation.

Today, I learnt about the reaction and did a displacement. Mainly the displacement reaction, A+Compound with metal C-----> C + Compound with A Where A is more reactive than C and it displaces it. What if A is less reactive than C? I found that some reaction still undergo where most of the reaction. I found that magnesium displaces iron(II) sulphate very fast. The reaction involve a large amount of heat released and even steam was produced. Why? Last, do the non-metals displace similarly? And is hydrogen more reactive than potassium to displace metals?

Single and/or Multiple Search Engines? What are they?

I see.Thank you for telling me
