What is the difference between O & O2 - Chemistry Stack Exchange
WEBJan 10, 2017 · 1. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules. Our atmosphere is made of mostly O 2, which our bodies have evolved to breathe. We breathe in O 2 and cellular respiration requires it (C 6 H 12 O 6 +6O 2 →6CO 2 +6H 2 O). O is oxygen, while O 2 is dioxygen.
Why does ozone have higher entropy than oxygen?
WEBSep 14, 2018 · This reaction is consistent with this rule of thumb. The relevant thermodynamic quantities are the standard Gibbs free energy, enthalpy, and entropy, of formation of ozone, since the oxygen is in its standard state. Taking the figures from this copy of CRC we have. ΔfG∘(O3) = 163.2kJmol−1 ΔfH∘(O3) = 142.7kJ mol−1.

WEBNov 17, 2014 · Provided you know the reactants and products (which you did) look for the oxidation numbers which change; in this case some of the chromium: down 3 and some of the oxygen: up 2. To balance the equation these must match, so for every 3 oxygen atoms in O2 there must be two chromium atoms in Cr2O3. Hence 2Cr2O3 + 3O2.
How does hydrogen and oxygen combine to make water?
WEBFeb 11, 2023 · Closed last year. When two hydrogen atoms fuse with one oxygen atom to create a molecule of water, each hydrogen atom donates its single electron to the oxygen atom, resulting in 10 electrons for the oxygen, instead of eight. But if the hydrogen atom no longer has its sole electron, is it still a hydrogen atom.

Is this endo or exothermic? - Chemistry Stack Exchange
WEB2. 4Fe +3OX2 2FeX2OX3(s) +1625 kJ 4 F e + 3 O X 2 2 F e X 2 O X 3 (s) + 1625 k J. This should be endothermic because the energy is in the product. However, if the equation is viewed from the perspective of the reactant, it is endothermic. Is this endo- or exothermic?
Chemical equilibrium and Le Chatelier's principle
WEB1) Increasing Oxygen pressure will increase the reverse rate because to reestablish equilibrium some of the oxygen should be consumed. 2) Out of system due to precipitation. 3) Out of system due to precipitation. 4) This is endothermic reaction. So increasing temperature will increase the forward rate to consume the added heat.
