Question 1

Question
What is the standard formula for a neutralisation reaction?
Answer
  • Acid + Water = salt + base
  • Acid + base = salt + water
  • Base + salt = acid + hydrogen
  • Acid + base = salt + hydrogen

Question 2

Question
How is a neutralisation reaction written in terms of H+ and OH- ?
Answer
  • H2O + H+ = Water + OH- +salt
  • OH- +salt = H+
  • H+ + OH- = H20
  • Water + H+ = OH- +H2O +salt

Question 3

Question
What is the formula for reacting an acid with a metal?
Answer
  • Acid +metal = salt + hydrogen
  • Acid + metal = salt + water
  • Acid + salt = metal + water
  • Water + salt + metal = acid

Question 4

Question
Which one of these is the correct balanced equation for the reaction between Hydrochloric acid (HCl) and Magnesium (Mg)? (Sorry no subscript)
Answer
  • HCl + Mg = MgCl2 +H2
  • 2Hcl + 2Mg = MgCl2 + H2
  • HCl + 2Mg = 2MgCl2 + 2H2
  • 2HCl + Mg = MgCl2 +H2

Question 5

Question
Which of these is the correct equation for the manufacture of Ammonium Nitrate (NH4NO3)? (sorry no subscript)
Answer
  • NH3 + 2HNO3 = NH4NO3
  • NH3 + HNO3 = NH4NO3
  • 2NH3 + 2HNO3 = NH4NO3
  • NH3 + 2HNO3 = 2NH4NO3

Question 6

Question
Acid + Metal oxide/hydroxide = ?
Answer
  • Salt + hydrogen
  • Salt + water
  • Salt +Water hydroxide
  • Salt hydroxide +water

Question 7

Question
Therefore, HCl + NaOH = ?
Answer
  • NaClOH + H2O
  • NaCl + H2OOH
  • NaCl + H2
  • NaCl +H2O
