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...

What is the difference between ionic and metallic bonding?

Ionic compounds are made up of charged atomic or molecular ions, the attraction between the oppositely charged ions holds the compound together. They don't conduct electricity, are soluble in water.

Explain why reactivity increases as you go down group 1 (alkali metals) of the periodic table (3 marks)

As you go down the group, there is an additional electron shell added each time (1). These electron shells hold negatively charged electrons that shield the positive nucleus from the outer shell electron....
