<span>Answer: 2COâ‚‚ (g) + 6Hâ‚‚ (g) → CHâ‚OCHâ‚ (g) + 3Hâ‚‚O (â„“) Now make this reaction up from what you are given: 2 Ă— (COâ‚‚ (g) + 3Hâ‚‚ (g) → CHâ‚OH (l) + Hâ‚‚O (â„“).. â†H° = –131 kJ) ... (2CHâ‚OH (l) → CHâ‚OCHâ‚ (g) + Hâ‚‚O (â„“) .. â†H° = 8kJ) ––––––––––––––––––––––––––––––––––––––... add 2COâ‚‚ (g) + 6Hâ‚‚ (g) → CHâ‚OCHâ‚ (g) + 3Hâ‚‚O (â„“) . - exactly what you want! â†H° = 2(–131 kJ) + 8 kJ = –254 kJ</span>

What does Le Chateliers principle say about upsetting a system at equilibrium
iragen [17]

Le Chatelier principle says, if a restriction is applied to a system in equilibrium, the system adjusts to a new equilibrium that tends to counteract the restriction. When equilibrium is under stress it will shift to relieve that stress.

or

all concentrations would change.

What is the mole ratio of d to a in the generic chemical reaction 2a+b-- c+3d?
barxatty [35]

Answer:  D : A is 3 : 2.

Explanation:

The law of definite proportion is being used here. The law states that a given compound always has the same proportion of its constituent elements by mass.  

2a + b = c + 3d

This actually means that, two moles of “a” react with a mole of “b” to produce a mole of “c” and 3 moles of “d”

Using the concept of stoichiometry coefficients of d and a  

d:a = 3:2
