CanadianLoser: Meow :3 :3; +1,148|6992

I just started chemistry after a year being away from it and forget some pretty simple shit, which is a tad embarrassing lol but i need it for this lab so i come to bf2s for help:

write word equations for each of the five reactions:

H2O + K = ?
H2O + Na = ?
H2O + Li = ?
HCl + Ca = ?
HCl + Zn = ?

karma to whoever can help

Water plus potassium produces...
Watter plus sodium produces...
Water plus lithium produces...
Hydrochloric acid plus calcium produces...
Hydrochloric acid plus zinc produces...

Like that?

Que? Are you balancing equations? Or just writing out the names for those equations? If the latter

Water + Potassium
Water + Sodium
Water + Lithium
Hydrochloric acid + Calcium
Hydrochloric Acid + Zinc

No. He wants

Water plus Potasium equals
Water plus Sodium equals
Water plus Lithium equals
Hydrochloric acid plus Calcium equals
Hydrochloric acid plus Zinc equals

By "word equations" do you mean just like saying "Water plus potassium yields blah blah blah"

Also, subscripts and superscripts. These forum features allow us to take full advantage of them!

Never say equals in chemistry, and oops at the embarrassing mistake of saying Hydrogen Chloride instead of hydrochloric acid... I need more sleep...

I had to say equals all the time in Physics, habbit has stuck.

yes, but i need you guys to tell me what they produce also!

Water plus Potasium yields aqueous potassium ions
Water plus Sodium yields aqueous sodium ions
Water plus Lithium yields aqueous lithium ions
Hydrochloric acid plus Calcium yields Calcium in hydrochloric acid solution
Hydrochloric acid plus Zinc yields Zing in hydrochloric acid solution

All the alkali ions are soluble in water and wouldn't react at all, they would just remain as ions in the water.
Neither of those metals form a compound with hydrochloric acid that I know of. If I am wrong I apologize, as this is all off the top of my head.

H₂O + 2K = H₂ + K₂O
Do the exact same with the other two H2O equations (2 infront of the metal in the reactants part)

2HCl + Zn = H₂ + ZnCl₂
2HCl + Ca = H₂ + CaCl₂

Someone please correct me if I'm wrong though. Pretty sure it's right but still...

edit: Silentscout that's what I thought but why would he have to predict the equation =/

I don't know, it's funny in AP Chem I am doing things a million times more difficult than this but for some reason as soon as it gets this simple it becomes almost more difficult...

We're actually covering balancing equations in chem now. If it was something like IDK... Zn + Ca(NO₃)₂ it'd be easy

Most metals produce oxides K₂O or hydroxides Zn(OH)₂
in water, although many metal hydroxides are soluble, and will not precipitate, and there will be no visible reaction.

I'm assuming all the metals listed will produce oxides.

Most Chloride compounds are soluble, so HCl might not produce a visible reaction, you may want to confirm what reaction will occur before writing anything down.

ZnCl₂ is highly soluble, and the reaction will produce Zn²⁺ ions in solution.

Apparently Zinc chloride is an acid, and I also think I am making this a million times more complex than it is. Especially considering you are saying you are just beginning again with simple things. Therefore I guess they want you just to pretend as if solubility rules don't exist and just do simple single/double replacements.

Stick with what Hurricane said and I think that is what your teacher wants. To put what hurricane said into a word problem:
H2O + 2K = H2 + K2O
Water plus potassium yields potassium oxide plus hydrogen.
Water plus Sodium yields Sodium oxide plus hydrogen.
Water plus Lithium yields Lithium oxide plus hydrogen.

2HCl + Zn = H2 + ZnCl2
Hydrochloric acid plus zinc yields zinc chloride plus hydrogen.
2HCl + Ca = H2 + CaCl2
Hydrochloric acid plus calcium yields Calcium chloride plus hydrogen.

(20:12:12) (@Hurricane) CanadianLoser, just a warning... SS could be right
(20:12:32) (@Hurricane) technically the potassium would just be an ion in an aqueous solution =/
(20:12:32) (+CanadianLoser) idk cause all those reacted when we tested them

Good enough for me

Water mixed with potassium yields hydrogen and potassium oxide
Water mixed with sodium yields hydrogen and sodium oxide
Water mixed with lithium yields hydrogen and lithium oxide
Hydrochloric acid mixed with zinc yields hydrogen and zinc chloride
Hydrochloric acid mixed with calcium yields hydrogen and calcium chloride

IDK about the forms, other than that Hydrogen will be a gas.

thanks to all that helped (especially hurricane and SS) you just made my life a lot easier hopefully they are right, which i am confident they are. thanks again

I guess this can be closed, or left to die open.

Eh? Unless my A2 chemistry has gone to complete shit, im sure Sodium + Water > Sodium Hydroxide + Hydrogen?

Balancing is so easy.

It's funny, in Icelandic we call K (potassium) Kalín and Na (sodium) Natríum

I never understood why it doesn't follow abbreviations in English.

H2O + K = Anthrax
H2O + Na = Trinitrotoluene
H2O + Li = Sarin
HCl + Ca = Cemtex
HCl + Zn = Table Salt

lol, Anthrax isn't a compound, it's a bacteria Bacillus I think it is.

never heard about Trinitrotoluene, sarin or cemtex, at least not in English and table salt is obviously Na + Cl

Dem be lies!
