storchak [24]
<span>In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. Balanced chemical equation for this reaction is given below. Na-sodium , H2o- water, H-hydrogen gas and NaOH- aqueous sodium hydroxide. Two atoms of Na react with two atoms of water and this reaction will give us H (hydrogen gas) and two atoms of NaOH (aqueous sodium hydroxide). 2Na + 2 H2o = H2 +2NaOH.</span>

9- Which pair of formulae represents two alkanes? (1 mark)
Ksenya-84 [330]

Answer:

A) CH4 and C8H18

Explanation:

  • General Formula for an Alkane = CnH2n+2

  • This means for every number of Carbon (C) atoms, there are twice as many Hydrogen (H) atoms with an additional two added onto that.

  • Therefore, if there is one Carbon Atom, and we multiply that by two, and then add an additional two, we get 4 Hydrogen atoms, so CH4, which is our first Formulae

  • Secondly, if we have eight Carbon Atoms, and we multiple that by two (16), and then add an additional two, we get 18 Hydrogen atoms, so C8H18, which is our second Formulae

  • The other Formulas do not follow this 'General Formula'
