english chemistry help.... please!!!?

Question

H2SO4 is ACID , NaOH is .... (is it called alkaline)
and Na2SO4 is...

Na is .... (is it called free substance?)
and when we react it with H2SO4, it will form Na2SO4...
what is
Na2SO4, CuSO4, Fe(OH)3, etc called??
I know their names, what I`m asking is, what is it called if a single metal are reacted with other substance and form a new substance which contains more than 1 element

and if u do speak Indonesian, please translate this words into English!!

massa ekuivalen =
atom =
senyawa =
garam (not only NaCl) =
basa =
hasil kali kelarutan (Ksp) =
hasil reaksi =
reaktan =
unsur bebas =
massa molekul relatif (Mr) =
ion =
bilangan oksidasi =
bilangan oktan =
harga mutlak =
koloid =
molaritas =
molalitas =
elektron =


I know my English is bad...
but please help me....

Answer 1

Wow. This one's a real challenge!

NaOH is an alkali, also called a base. (the adjective is "basic" or "alkaline")

Na is a an element (also an alkali metal)
Na2SO4 and CuSO4 could be called salts. When you react an acid and a base, you usually get a salt.
They could also be called compounds. A compound is a molecule made up of different kinds of atoms.

I don't speak Indonesian, but I had to learn to read Tok Pisin a while ago, and this looks similar. A lot of the words you wrote are phonetically similar to English words in chemistry.

massa ekuivalen = mass-equivalent
atom = atom
garam = could this be salt, in a general sense? I could not find it in an ordinary online dictionary of English/Indonesian.
basa = base (probably)
reaktan = reactant
unsur bebas = ?? but unsur kimia appears to mean an element (as in the periodic table, tabel periodik)
massa molekul relatif = relative molecular mass, which is probably the same as "molecular weight". If this is correct, it should have units of grams/mole
ion = ion
bilangan oksidasi = valence? oxidant or oxidizer?
bilangan oktan = octane number?
koloid = colloid
molaritas = molarity
molalitas = molality
elektron = electron

senyawa: judging by the entries in the indonesian wikipedia,
http://id.wikipedia.org/wiki/Kategori:Senyawa_kimia
I would translate senyawa kimia as a chemical substance or chemical compound.

Hmm, I see quite a few of these words in the Indonesian wikipedia. Try searching for the translations I proposed in the English language wikipedia, and see if the explanations there correspond to the explanations in the Indonesian one.


Don't apologize for your English, it's a LOT better than my Indonesian!

Answer 2

H2SO4 is an ACID (It is ACIDIC - this is the adjective form.)

NaOH is a BASE (It is BASIC, or ALKALINE) ("Basic" is the term most often used today.)

A solution that is not Acidic or Basic (which therefore has a pH of 7.0) is NEUTRAL.

Na is an ELEMENT.

Na2SO4, CuSO4, Fe(OH)3, etc. are COMPOUNDS.

I don't speak Indonesian, but a number of the words you listed are quite close to the English, so I'll take a guess ...

massa ekuivalen = equivalent mass
atom = atom
senyawa = ?
garam (not only NaCl) = salt
basa = base
hasil kali kelarutan (Ksp) = ?
hasil reaksi = ?
reaktan = reactant or reaction?
unsur bebas =
massa molekul relatif (Mr) = relative molecular mass
ion = ion
bilangan oksidasi = ----- oxidiser?
bilangan oktan = ?
harga mutlak = ?
koloid = colloid
molaritas = molarity
molalitas = molality
elektron = electron

Hope that helps.

Answer 3

its called ionic compound bonding between metal and non-metal or covalent compound bonding between non-metals but I am not sure of most of the translations
