The method of production of sea salt usually involves bulk evaporation of seawater. This allows the salt to crystallise and due to it's bigger size it is sold without much processing. On the other ...

Relative atomic mass is a dimensionless quantity. It is relative mass of a specie with respect to the mass of carbon-12. So the units of masses get cancelled and hence we have a 'unitless' quantity. ...

I remember my days when I started confusing myself in the exact same way. The issue I believe is that you haven't been explained the details of how all this happens. Evaporation: All molecules in a ...

Enthalpy vs ∆Enthalpy We know that enthalpy represents the energy of a system. So, now think about it? Measuring the energy of a system? Consider all the changes and influences a system is under. This ...

It is true that sometimes uracil could be present in DNA. Uracil is almost exclusive to RNA but in some cases deamination of cytosine can cause uracil to be present in DNA. I believe what Chargaff ...

If we try to answer this question at a rather simple level, we could say that yes the ions can exist in a particle-free environment like vacuum. But if ions are formed in an aqueous medium, like the H+...

Let me explain it in a less complicated and direct way. H+ 'reacts' with H2O to form the hydronium because the oxygen in the water molecule has a lone pair of electrons that attracts the H+ ion. Why ...

I would say yes, the -CH3 group adds a little +I effect, making the -CH=CH-CH3 a little less electron withdrawing compared to the vinyl.
