Molecular formula of sulfur trioxide is SO₃
Molar mass of SO₃ is - 32 + (16 x 3 ) = 80 g/mol
1 mol of any substance consists of 6.022 x 10²³ units. In 1 mol of SO₃ there are 6.022 x 10²³ molecules of SO₃
in 80 g of SO₃ - there are 6.022 x 10²³ molecules of SO₃
Therefore in 78 g of SO₃ - there are 6.022 x 10²³ /80 x 78 = 5.871 x 10²³ SO₃ molecules
Answer:
d
Explanation:
a) This is not an equation.
b) This is not an equation.
c) The reactant side has 1 Na and 2 O while the product side has 2 Na and 2 O, therefore it is not balanced
d) The reactant side has 4 H and 4 O and the product side has 4 H and 4 O, therefore it is balanced.
The ionization reaction of the compound given are as follows:
1.) HI(aq)
HI(aq) -----> H+(aq) + I-(aq)
2.) LiOH(s)
LiOH(s) ------> Li+(aq) + OH-(aq)
Ionization<span> is the process by which an atom or a molecule acquires a negative or positive charge. Hope this helps. Have a nice day.</span>
