Make up the chemical phorules of the acids corresponding to the oxides, the formula of which is SO2; SiO2; CO2; N2O5? What are the names of all acids?

1. In this case, everything is very simple. So to the presented acidic oxides, you need to add a water molecule.

From CO2 we get H2CO3 and this is carbonic acid.
From N2O3 we get HNO3 and this is nitrous acid.
From P2O5 we get H3PO4 and this is phosphoric acid.
From SiO2 we get H2SiO3 and it is silicic acid (very unstable in air).
From SO2 we get H2SO3, which is sulfurous acid.

2. When mixing, sulfuric acid (in a thin stream) is gradually added to water. But on the contrary, it is impossible, since you can spray and naturally burn yourself.
