H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Concordant titres: 26.15 cm³ and 26.25 cm³
Mean titre: (26.15+26.25)/2= 26.2 cm^3...

To work this out we need the equation:
Number of moles = Mass (in grams) / Mr (relative formula mass)
We know the mass of carbon dioxide already (88g). We need to work out the Mr of carbon dioxi...

Alkali metal have 1 outer electrons. Reactivity increases down the coloumn.

The enthalpy Change of Hydration for cyclohexene is 120 kJmol^-1 therefore if the Kekule model is correct then the Enthalpy change of Hydration would be 360 kJmol^-1 however as it is c...

Both molecules have a C-Br bond, which will be polar due to their difference in electronegativities (bromine is more electronegative than carbon). In CBr3CBr3 the dipoles cancel so the overall molecule is...
