Re: Temperature effect on the reaction
Figur out if the reaction is exothermic or endothermic.
If exothermic equilibrium shifts left, if endothermic it shifts right, if temperature is increase.

Re: please help
Which one
1,2-Propylene glycol or 1,3 Propylene glycol
But above you write in opposit direction
Propylen glycole down to ethylen glycole
Ethylenglycole to Glycolaldehyd HOCH2CHO
Glycolaldehyd + Methylgrignard => 1,2- Propylenglycol
1,2-Propylene glycol or 1,3 Propylene glycol

Ok, where should the carbondioxide comes from?

Re: My question really is where does the disulfide bridge go
Normaly the Disulfid will connect two Polymer chain or the same chain for folding each other. Its also called crosslinking.

Re: Mg(OH)2 + CaCO3 + H2O = Mg(HCO3)2 + Ca(OH)2
I dont think so, because the equilibrium will be on left side. Two precipitate on left and on right side only one.
Check the solubility constant from each product.
Also hydrogencarbonate is slightly acidic. Calcium hydroxide strong alcaline, this will neutralise.

Re: Mg(OH)2 + CaCO3 + H2O = Mg(HCO3)2 + Ca(OH)2
First the equation is not balanced, second why do you think this should happen. To get hydrogencarbonate excess of carbondioxide is needed.
This works without and with the calcium already.
Can be find in stalactite caves.

Re: Question on Molarity and Solubility
Read the principles of Le Chatelier. Here you make from two reactants one product. So it means decrease Volume or increase pressure will give more product .Figure out is the reaction exothermic or endothermic. Means consume or release heat. If it consumes rise temperature, in other case decrease tem...

Re: I need help with some questions and types of problems
1. Soap is made of amphipathic particles, the hydrophil part dissolves in water the hydrophob part in fat or oil. The soap molecules develop micelles. A dirt particle is fatty, so the particle will be surounded from the soap molecules, by stickig the hydrophob part in. The hydrophil part will be in ...

Re: Understanding the Equilibrium Constant Expression
Law of mass action
K = C^c*D^d/(A^a*B^b)
K = constant, so changes of one component will affect all others.
