Hello, I just need some help on these questions and some explaining.

What to do:
> Balance each of the following chemical equations.
> Identify the type of chemical reaction (Decompostion, Combustion and Synthesis)
> Write the condensed word equation

A) Li + Hg(ClO)_2 \xrightarrow~Hg + LiClO

B) C_8H_1_8 + O_2 \xrightarrow~CO_2 + H_2O

C) KOH + FeCl_3 \xrightarrow~KCI + Fe(OH)_3

D) Au + O_2 \xrightarrow~Au_2O

E) KCI\xrightarrow~K + Cl_2

F) Ni + Cl_2 \xrightarrow~NiCl_3

I know how to balance equation, for example; letter F would be:

F) 2Ni + 3Cl_2 \xrightarrow~2NiCl_3

I also know how to identify the type of chemical reaction, for example; letter F would be:
F) Ni + Cl_2 \xrightarrow~NiCl_3 \xleftarrow~ Synthesis

I need to know how to write a consedensed word equation.



And How would you write this out into a chemical equation:
A solution of carbonate and hydrogen hydroxide are produced when limewater reacts with your breath.




Thanks :smile:

What is your breath composed of? If you know that, all you need to do is balance the equation and know formulas for carbonate and hydrogen hydroxide.

To write a condensed word equation just follow the example you have given

As courtigrad mentioned, the quoted sentence is itself an example of such a word equation. You just want to substitute each chemical formula with the correct chemical name (see this link (http://members.tripod.com/~EppE/formulas.htm) for help with naming compounds) and if possible, mention what type of reaction is happening.

Let me do one :

B) Octane combusts completely in oxygen ('air' may be acceptable too) producing carbon dioxide and water vapor.

I've made use of the knowledge that the reaction is a combustion reaction, and I've also mentioned that water is in the form of vapor, which I know because such combustion reactions usually produce a lot of heat.

As for your other question, I suggest you Google it to find out for yourself. IMO, it's a little too much to expect someone who hasn't heard of this reaction (it's quite a popular one) to know that it's the CO2 in your breath that's important.

What do write for limewater?
I know breath is CO2

Did you even try to Google "breath limewater" ?

[b]A) Li + Hg(ClO)_2 \xrightarrow~Hg + LiClO
Maybe: Lithium + Mercury(II) Chlorine oxide ------> Mercury + Lithium Carbonate

B) C_8H_1_8 + O_2 \xrightarrow~CO_2 + H_2O
Maybe: Hydrocarbon + oxygen ------> Carbonate + Water

C) KOH + FeCl_3 \xrightarrow~KCI + Fe(OH)_3
Maybe: Potassium Hydroxide + Iron Chlorate ------> Iron (III) Hydroxide

D) Au + O_2 \xrightarrow~Au_2O
Maybe: Gold + Oxygen ------> Gold oxide

E) KCI\xrightarrow~K + Cl_2
Maybe: Potassium Carbon Iodine ------> Chlorine

F) Ni + Cl_2 \xrightarrow~NiCl_3
Maybe: Nickel + Chlorine ------> Nickel Chloride

Are the word equation correct?
Please tell me, I have to hand this in and it is worth alot of marks/

Thanks :smile:
