I'm thinking a hypothesis theory, form a guess and proceed to experiment your hypothesis, leading to a definate theory....
Well even though im not giving you the whole answer, Im going to tell you what to do in order for you to do it. The main thing you need to do is to determine the delta H and delta S for the reaction.<span>Then subtract the reactants from the products.
On eexample of this is: </span><span>Delta H = (-634.9(CaO)+-393.5(CO2)) - (-1207.6 (CaCO3)) = 179.2 kJ
</span><span>Do the same thing for Delta S but make sure you use the correct units. Delta S is in Joules so you may need to convert. Once you have those values, plug into the equation
</span><span>Delta G= Delta H - T * Delta S
</span>And you will get your result
hope this is very useful for you
The mass of 0.015 moles of na2so4 is 2.13 grams.
Define number of moles.
The ratio of a substance's given mass in a chemical reaction to the mass of one mole of that substance is the number of moles of that substance. A mole of any substance is equal to 6.023 1023, Avogadro's number.
Number of moles (n) = 0.015 mol
Molar mass of Na2SO4 = 142.04 g/mol
Required Mass (in g)
= Number of moles × Molar mass
= 0.015 mol × 142.04 g/mol
= 2.13 g
Therefore, the required mass is 2.13 g.
