Reduce the following molecular formulas to empirical formulas. Please help!
zvonat [6]
This is done by reducing each number by a common factor for each formula.

C3H6O6- all can be divided by 3 -> CH3O3 (you don't have to put a 1 for C, only if your teacher requests it. It is generally understood if not written)

H2O2- all can be divided by 2 -> H1O1 (had to put the 1's bc of the unintended language) 

C8H8S2- all can be divided by 2 -> C4H4S 

P5O15- all can be divided by 5- PO3

*****it is important to note that <em>all </em>numbers in the molecular formula are divided by the same thing to reduce them. decimals are <em>never </em>used in empirical formulas, only whole numbers.*****

What stress will shift the following equilibrium system to the left? N2(g) + 3H2(g) ⇌ 2NH3(g)
oee [108]
<h3><u>Answer;</u></h3>

Decrease in pressure

<h3><u>Explanation;</u></h3>
  • If the pressure of a system is increased, the reaction will shift toward the side with fewer moles of gas, whereas when the pressure of a system is decreased, the reaction will shift toward the side with more moles of gas.
  • In this case; <em><u>If the pressure of the system with the above reaction decreases, the reaction will shift to the left. The reactants side has more moles of gas, so the reaction will shift toward the direction of the reactants.</u></em>
