### Why is the hybridization of SO4, sp3?

I've read about sp, sp2, and sp3 and understand that for sp there will be 2 sp orbitals, b/c there is an sp, and for sp2, there will be 3 sp orbitals, and so on and so forth. But I'm still having ...

### Is a hydrocarbon bio-battery feasible?

Hydrocarbons have some of the highest energy densities and specific energies of any chemical fuel. Unfortunately, our primary use of them is in thermal engines, whose efficiency is limited by Carnot'...

### Thermodynamic State Function vs Path Function

The change in various state function is said to be a path function like (changes in) enthalpy(delta H), gibbs free energy(delta G), temperature(delta T), etc. But only the change in internal energy is ...

### Why does the graph of probability distribution of an electron peak at values close to 0?

I do not understand how this graph peaks at values close to $0$. I understand that it is the probability distribution of the electron for a $2\mathrm s$ orbital of $\ce{H}$ atom, but shouldn't it ...

### Calculate the number of atoms of water and Glucose to fit in a 40 angstrom box with a given density

Suppose I want to have a 40 angstrom cubic box with a 0.5 mole fraction of water and 0.5 mole fraction of glucose. I am trying to determine the number of water molecules and glucose molecules that ...

### Conjugated diene + Na in liq.NH3

I learned that alkynes gets reduced on addition of $\ce{Na}$ in liquid $\ce{NH3}$ to form alkenes (which is not further reduced). Recently I came across a reaction where a conjugated diene was treated ...

### Why is the reverse aldol cleavage of fructose 1,6-bisphosphate highly endergonic under standard conditions?

I have another question similar to this one. I just don't have intuition for why reactions are thermodynamically favorable or unfavorable and I'd like to build it. This time I'd like to ask about ...

### Radial node in p or d-orbital

While studying atomic orbitals and nodes, the only illustration of a radial node that I could find is in an s-orbital (like here). How do the radial nodes look like in p or d-orbitals? (I don't know ...

### Regioselectivity in the single dehydrohalogenation of 1,2,3 trichloropropane

I am wondering if when 1,2,3 trichloropropane is dehydrohalogenated if 2,3 dichloropropene is favoured or if both isomers are made (ie 1,3 dichloropropene).

### Need help to calculate results of an electrochemistry cell potential lab work

So, the lab work is this. I made an AgCl electrode of a silver wire by coating it with AgCl. This was done by electrolysis by immersing the wire in HCl and using platinum as a counter electrode and ...

### Balancing reaction between copper (I) sulfide and nitric acid

Question What is the sum of stoichiometric coefficients of redox reaction: $\ce{Cu2S + HNO3 -> S + NO2 + Cu(NO3)2 + H2O}$? Answer 23 This is from a multiple choice exam, I calculated the sum of ...

### Evaluation of n-factor for the given type of chemical reactions

For the reaction: $$\ce{3I_2 + 6NaOH -> NaIO3 + 5NaI + 3H2O}$$ Calculate the $n$-factor and hence the equivalent weight of $\ce{I_2}$ and $\ce{NaOH}.$* *$n$-factor of an element in a reaction is ...

### Product formed on heating of one molecule of ferrous sulphate

I know that given heat, 2 molecules of anhydrous $\ce{FeSO4}$ decompose to form various substances. i.e. $$\ce{2FeSO4 (Heat) —> Fe2O3 + SO2 + SO3}$$ Now suppose I have a box of complete vacuum and ...

### Acid Dissociation [duplicate]

I have a small confusion If suppose HA is a acid then , HA gives H+ and A- ions in water. The presence of H+ implies that the solution is acidic. OK fine... but I came across that this solution will ...

### Cyclohexene and Benzene [closed]

If cyclohexene and benzene are both reduced to (adding $H_2$ until saturation) cyclohexane, which of the two will have similar experimental and theoretical values, and why? According to the internet, ...
