Write down the equations according to the schemes: a) phosphorus oxide (V) + water = phosphoric acid
Write down the equations according to the schemes: a) phosphorus oxide (V) + water = phosphoric acid b) hydrochloric acid + aluminum = aluminum chloride + hydrogen c) silver nitrate + iron (III) chloride = silver chloride + nitrate d) aluminum hydroxide = aluminum oxide + water
a) The reaction takes place between substances such as pentavalent phosphorus oxide and water. Phosphoric acid is formed. We write the reaction equation like this:
P2O5 + 3 H2O = H3PO4
b) The reaction takes place between substances such as hydrochloric acid and aluminum. Aluminum chloride and hydrogen are formed. We write the reaction equation like this:
6 HCl + 2 Al = 2 AlCl3 + 3 H2
c) The reaction takes place between substances such as silver nitrate and ferric chloride. Formed silver chloride and ferric nitrate. We write the reaction equation like this:
3 AgNO3 + FeCl3 = 3 AgСl + Fe (NO3) 3
d) The reaction of decomposition of aluminum hydroxide into aluminum oxide and water. We write the reaction equation like this:
2 Al (OH) 3 = Al2O3 + 3 H2O.
