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.

Elements are arranged in rows, referred to as periods, of increasing atomic number. To recap, atomic number is the number of protons in the nucleus of an atom. Elements are also arranged in columns, refer...

Because carbon atoms have 4 electrons in their outer shell so always form 4 covalent bonds in a molecule, so the number of hydrogen atoms bonded can be inferred by subtracting however many bonds the carbo...
