THe balanced chemical reaction would be:
Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2
We first convert the mass of sulfuric acid solution to moles by the molar mass. Then, we relate H2SO4 with Na2CO3 from the reaction. We do as follows:
<span>6.05×10^3 kg H2SO4 ( 1 kmol / 98.08 kg) ( 1 kmol Na2CO3 / 1 kmol H2SO4 ) ( 105.99 kg / kmol ) = 6537.92 kg Na2CO3 needed</span>
Initial buret reading means the volume of acid taken in the buret and final reading means the remaining volume of acid after experiment
ok, here is a sentence for you:
Frost wedging is a process that is an occurrence when ice forms in a tiny crack of a rock and then i breaks slowly melting away and eroding the surface of the rock or mineral etc.
I hope this helps you!
Answer is: c. 6.02 x 10^23.
n(N₂) = 1.00 mol; amount of nitrogen molecules.
Na = 6.02·10²³ 1/mol.
Na is Avogadro number or Avogadro constant (the number of particles, in this example nitrogen molecules, that are contained in the amount of substance given by one mole).
N(N₂) = n(N₂) · Na.
N(N₂) = 1.00 mol · 6.02·10²³ 1/mol.
N(N₂) = 6.02·10²³; number of nitrogen molecules.
