This question test knowledge of the geometry of equilateral triangles and the students ability to solve linear equations. First we note that an equilateral triangle has equal sides. Then we can write that x+...

"Electronegativity is the power of an atom to attract the electron density in a covalent bond to itself " In order to understand electronegativity we must understand that electrons orbit the nucleu...

The genotype of an organism is the combination of alleles, different copies of a gene at the same locus, (from the mother and father) that give rise to a particular trait whereas the phenotype is the observa...

Recall that to solve a quadratic it needs to be in the form ax 2 + bx +c = 0, Subtract 2 from each side to get 2x 2 -x-6=0 therefore a=2 b=-1 and c=-6 Solve by considering factors c and a that expand out to ...

Graphite is made from layers of carbon which contain many 6-membered carbon rings (hexagonal). Each layer is held together by each carbon being covalently bonded to 3 other carbon atoms and this leaves a del...
