WebThe reaction is believed to be bimolecular: NO(g)+F2(g)→NOF(g)+F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons, tend to be … Web- Can there be a reaction, which has ∆H = 0, so that the energy of reactants (e.g 500Kj) and products (e.g 500Kj) is equal, so that the enthalpy of reaction is zero (∆E = 500 - 500 = 0)? - I read that the enthalpy also depends on the state of the reactants, e.g when oxygen and hydrogen gases react to produce water vapor, the enthalpy change ...

WebAug 21, 2024 · For F 2 2) is less than for Cl 2 but since the energy needed to break the F-F bond is also less and the hydration more, the total energy drop is much greater. In spite of their lower atomization energies, Br 2 and I 2 are weaker oxidizing agents than Cl 2 and this is due to their smaller Δ EA H 1 and smaller Δ hyd H°. WebJul 8, 2024 · F2 Forces – True or False. Contact forces are forces that act on objects through direct contact. Friction【摩擦力】 is an example of non-contact force. Friction is an example of contact force. Friction always opposes【抵抗】 the motion of an object. The friction between the tyres of a moving car and the road surface is greater when ... factory facility

Ionization energy is the energy required to remove a valence electron from an atom or ion in its gaseous state, causing it to gain a positive charge as the electron is removed. "X" + "energy"rarr"X"^(+) + "e"^-" Fluorine is in period two of the periodic table, meaning that it contains electrons in only the first two energy levels at … WebThe metal reactivity series is a list of metals arranged in the order of their decreasing activities. The metals at the top of the series (K, Na, Ca, Mg and Al) are so reactive that they are never found in nature as free elements. It is difficult to separate them from their compounds and extract. The metals at the bottom of the activity series ... does university of pennsylvania require css
