Sulfuric acid

Sulfuric acid is

• Oily liquid

• metal

• natural rock

• gas

by adding sulfuric acid to water, the reaction is:

• reaction does not happen

• exothermic

• endothermic

• causes fire

the chemical formula of sulfuric acid is

• 2H(SO4)2

• H2SO3

• H2SO4

• 2HSO4

Sulfuric acid is used in: (select 2)

• fertilizers

• nuclear bomb

• pigments

sulfur is burned in air to get:

• SO

• SO3

• SO2

2SO2 + O2 ⇌ 2SO3 is reversible reaction.

best conditions for the gases are: ( select 3)

• 400 - 450 °C

• 100 - 200 atm

• 1-2 atm

• catalyst Sodium (Na)

• catalyst Vanadium (V)

SO3 + H2SO4 -> H2S2O7 is:

• extremely exothermic

• becomes endothermic

• creates acid that is thread for the environment

• causes death for people

Sulfur trioxide, SO₃ is dissolved in 98% sulfuric acid, H₂SO₄, to produce:

• sulfuric acid (H2SO4)

• oleum ( H2S2O7)

• sulfur trioxide (SO3)

Solid sulfur is burned in air to form sulfur dioxide gas. find the correct formula

• 2SO₂ + O₂→ 2SO₃

• 2S + O₂→ SO2

• S2 + 2O₂ → 2SO₂

• S + O₂ → SO₂

Billy was a chemist's son/

But now he is no more/

'Cos what he thought was H20/

Was H2So4.
