In which reaction does the oxidation number of oxygen increase? in which reaction does the oxidation number of oxygen increase?

2so2 (g) + o2 (g) → 2so3 (g) mgo (s) + h2o (l) → mg(oh)2 (s) 2h2o (l) → 2h2 (g) + o2 (g) ba(no3)2 (aq) + k2so4 (aq) → baso4 (s) + 2kno3 (aq) hcl (aq) + naoh (aq) → nacl (aq) + h2o (l)?

The answer is :

2H₂O (l) ------>2H₂ (g) + O₂ (g)  

That is ,

Oxidation number of oxygen increases in reaction :

2H₂O (l) ------>2H₂ (g) + O₂ (g)  

In H₂O, oxidation number of oxygen is -2 but in O₂ molecule it is 0.

So, oxidation number of oxygen increases in this reaction that is from -2 to 0.

So in the reaction that is 2H₂O (l) ------>2H₂ (g) + O₂ (g) ,  oxidation number of oxygen increases .

Given the unbalanced equation below, how many moles
Svet_ta [14]

Answer: 6 mol Li

Explanation:

The first step is to balance the equation.

2Li+Cl₂⇒2LiCl

We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.

6molLiCl*\frac{2molLi}{2molLiCl} =6molLi

Your TLC results for ortho-hydroxyacetophenone versus para-hydroxyacteophenone will indicate that one compound is significantly
Sloan [31]

Answer:

2-hydroxy

Explanation:

The 4-hydroxy has a reduced dipole because its two electronegative substituents give it a dipole in opposite directions. On the other hand the 2-hydroxy has dipoles that add together.

The electronic configuration of a ground-state Cr-atom :

1s²2s²2p⁶3s²3p⁶4s²3d⁴

<h3><u>What are electronic configurations?</u></h3>

The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.

According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.
