Pregunta 1
Pregunta
What is the standard formula for a neutralisation reaction?
Respuesta
-
Acid + Water = salt + base
-
Acid + base = salt + water
-
Base + salt = acid + hydrogen
-
Acid + base = salt + hydrogen
Pregunta 2
Pregunta
How is a neutralisation reaction written in terms of H+ and OH- ?
Respuesta
-
H2O + H+ = Water + OH- +salt
-
OH- +salt = H+
-
H+ + OH- = H20
-
Water + H+ = OH- +H2O +salt
Pregunta 3
Pregunta
What is the formula for reacting an acid with a metal?
Respuesta
-
Acid +metal = salt + hydrogen
-
Acid + metal = salt + water
-
Acid + salt = metal + water
-
Water + salt + metal = acid
Pregunta 4
Pregunta
Which one of these is the correct balanced equation for the reaction between Hydrochloric acid (HCl) and Magnesium (Mg)? (Sorry no subscript)
Respuesta
-
HCl + Mg = MgCl2 +H2
-
2Hcl + 2Mg = MgCl2 + H2
-
HCl + 2Mg = 2MgCl2 + 2H2
-
2HCl + Mg = MgCl2 +H2
Pregunta 5
Pregunta
Which of these is the correct equation for the manufacture of Ammonium Nitrate (NH4NO3)? (sorry no subscript)
Respuesta
-
NH3 + 2HNO3 = NH4NO3
-
NH3 + HNO3 = NH4NO3
-
2NH3 + 2HNO3 = NH4NO3
-
NH3 + 2HNO3 = 2NH4NO3
Pregunta 6
Pregunta
Acid + Metal oxide/hydroxide = ?
Respuesta
-
Salt + hydrogen
-
Salt + water
-
Salt +Water hydroxide
-
Salt hydroxide +water
Pregunta 7
Pregunta
Therefore, HCl + NaOH = ?
Respuesta
-
NaClOH + H2O
-
NaCl + H2OOH
-
NaCl + H2
-
NaCl +H2O
