nitrate acid and copper

    what happens when put copper in this acid  .nitrate acid is a very strong acid it is the only acid that can dissolve copper why is that post in the comments .                                                            





   here is a picture of copper reacting with nitrate acid .

cerium

on earth cerium is almost as abundant as copper (29) and is quite inexpensive especially in the form of cerium oxide widely used as an abrasive powder for polishing glass . cerium metal  is pyrophoric  witch
meaning that it can catch fire when scratch,file or grind it. in practice that dose not mean the hole lump caches fire but rather that the shavings burn as formed making the material very sparky . not surprisingly this makes cerium useful in liter flints where is highly pyrophoric nature is moderated by alloying it with iron (26).
 large lumps of undiluted mischmetal  lanthanum-cerium mixtures described under lanthanum (57) are used in movie special effects to create  large sparks.cerium has a atomic number of 58 atomic mass of 140 and atomic symbol of ce.

the soft metals

the soft metals are known as cu ag au the metals sit in one column on the periodictabal of elements
the real name for them are copper gold and silver these are non magnetic metals

metal hydroxides

HCI + NAOH = NACL + H2O.
2HNO3 + CUO = CU[NO3]2.
2HCI + K2CO3 = 2K2CL3.
AL + O2 = AL[O].
FE + H2O + O2 = FEO.

why was my plant water poisonous?

I found out that my plant water was poison because when I put ph in it, it turned  blue so I did some research and I found that it was infected with a chemical compound called alkali and that it turns ph blue.

how to make carbonated water

In this video I will be showing how to make carbonated water. Please rate and comment.

Dangerous Plant Water

I discovered that the water in my plant was poisonous when I put ph in it I compared it to my chart but it didn't match.

What I've learnt about Hydrogen

Hydrogen is the first element on the periodic table. It has an atomic number of 1. It is highly flammable and is the most common element found in our universe.

Carbon Facts

Carbon comes in a number of different forms (allotropes), these include diamond, graphite and impure forms such as coal.
