What is the difference between an atom and an ion? Explain the difference between an Na (sodium) atom and Na+ ion.

An atom is a neutral particle, an ion is a charged particle.Taking a sodium (²³Na) and sodium ion (Na⁺) as an example:Firstly, we need to break down both into their subatomic particl...

Explain how CH3CH2CHO can react with a Grignard reagent to produce CH3CH2CH(OH)CH2CH3. State the reagents and give the mechanism.

Use the Grignard reagent CH₃CH₂MgBr. CH₃CH₂CHO + CH₃CH₂MgBr ---> CH₃CH₂CH(OH)CH₂CH₃step on...

explain what an enantiomer is

an enantiomer is two molecules that are mirror images of each other, the best way to visualise it is to draw the molecule in a tetrahedral shape around the central carbon atom, then draw a line down the p...

Use the following information: [[[[2H2(g) + O2(g) → 2H2O(l) ∆H = −572 kJ mol−1]]]] [[[[2H2(g) + O2(g) → 2H2O(g) ∆H = −484 kJ mol−1]]]] to calculate the enthalpy change for the process: H2O(g) → H2O(l)

Well the method I use for calculations in thermochemistry is a little different from the textbooks but is far easier to understand.

I would approach this question by drawing out the chemical equat...

Explain why graphite can conduct electricity.

Graphite is structured as layers of carbon atoms arranged in 6 atom planar rings. Each carbon atom forms three bonds to neighbouring atoms meaning that each eatom has an unbonded alectron. This unbonded e...
