2NaHCO3 -> Na2CO3 + H2O + CO2
<span>2.765g NaHCO3/MM = moles NaHCO3 </span>
<span>moles NaHCO3 x (1 mole Na2CO3 / 2 moles NaHCO3) x MM Na2CO3 = theoretical yield of Na2CO3 </span>
<span>Percent yield is simply the actual yield/theoretical yield (x100 to put it into percentage).
MM = Molar mass (grams of substance per mol)</span>
I have heard they can use hair is stocking or nets to absorb the oil out of the water
Answer:
Arrhenius acid
Bronsted-Lowry acid
Explanation: just answered on e2020
Le Chatelier's Principle states that the system tries to lower the effect of the newly added change, to maintain equilibrium. In this equation, CO2 and H2O react to form H2CO3, which then dissociates into HCO3^- and an H atom, and then further into CO3^2- and 2 H^+ ions.
If we suddenly add more CO2 molecules into the system, this would cause equilibrium to shift to the right, forming more H2CO3, and consequently, more HCO3^-, CO3^2-, and H^+ ions.
There are many techniques in separation processes that can separate solution with many components. these separation processes depends in the nature of the solution. example of separating many components from a solution are fractional distillation and centrifuge.
