legit.

Uh, wouldn't do anything to the temperature.. it would disrupt the equilibrium, releasing more CO2 gas.

The changing states of CO2 releases/absorbs heat
beaten

 

[hscishard]

yes indeed 100% needed - see it in EVERY single CSSA exam =) hahaha

This sarcasm or what? I've never learnt that

What are all the formulas we should remember? Exclude any that may be in options.

also the combustion of ammonium permanganate
2 NH4MnO4 → 2 MnO2 + N2 + 4 H2O

was thinking the same thing wtf

 

[s2 SEductive]

What is the conjugate base of all these:

• Hydrochloric acid
• Sulfuric acid
• Hydronium ion
• Hydrogensulfate ion
• Acetic acid
• Carbonic acid
• Ammonium ion
• Hydrogencarbonate ion
• Water
• Hydroxide ion

I Will rep those who answer it the quickest correctly =]

 

[adz1098]

this is a pretty noob question, but in equilibrium if pressure is changed and there are equal moles on prod and reactancts what way does it shift or is their no shift

 

[RANK 1]

depends if they're all gases or not

Some of your answers are wrong. Keep trying!

just some of the basic equations you need to know

oxidation of acetone peroxide: 2 C9H18O6 + 21 O2 → 18 H2O + 18 CO2

combustion of erythritol tetranitrate: C4H6N4O12 → 4 CO2 + 3 H2O + 2 N2 + ½ O2

production of methyl nitrate: CH3OH + HNO3 → CH3NO3 + H2O

formula for THC: C21H30O2

 

[zxreth]

off the top of my head for acidic environment equations you need to know:

for solubility of CO2 in water
CO2 <==> CO2 + heat
CO2 + H2O <==> H2CO3

Acid Rain Equations
CO2 + H2O <==> H2CO3
SO2 + H2O <==> H2SO3
2NO + O2 <==> 2NO2 (from photochemical smog)

Natural Buffer (Blood)
CO2 + H20 <==> H2CO3
H2CO3 + H20 <==> HCO3- + H3O+

This should be it, unless i missed something

It's the oxide ion, but i'll rep you anyways!
