From the equation we can see the the line in a positive quadratic graph. In order to find the points where the line crosses the x axis we must let y=0 and solve for x. We can then use either inspection, c...

Orbital hybridisation is a model used to explain covalent bonding in molecules. It involves the merging of orbitals that are on the same energy level to form new hybrid orbitals.

Orbital hybridisat...

The formula mass (Mr) of FeSO4 is the total mass of all the individual elemenets added together. So the Mr of FeSO4 = (1 x Fe) + (1 x S) + (4 x O) = 56 + 32 + 4x16 = 152 To calculate moles, the equation f...

Firstly write out the question. x^2+5x+6. After this look at the constant without any x's. In this case that number is 6. Now look at the number 6 and work out the combination of factors for 6. Do this su...

Transcription factors together with enzymes such as DNA topoisomerase and DNA helicase reach the gene of interest. These enzymes uncoil the DNA and revelea the two strands of DNA that are wrapped around h...
