Answer:
The answer to your question is: 81%
Explanation:
Data
CaO = 2 g
Ca(OH)₂ = 2.14 g
Reaction balanced
CaO + H₂O ⇒ Ca(OH)₂
Molecular mass
Calcium oxyde = 40 + 16 = 56 g
Calcium hydroxide = 40 + 2 + 32 = 74 g
Process
Rule of three
56 g of CaO -------------- 74 g of Ca(OH)₂
2 g of CaO ------------- x
x = (2 x 74) / 56
x = 2.64 g of Ca(OH)₂
Percent yield
% Yield = 
% yield = 81
The formula that connects Ka1, Ka2, and Ka3 is the relation;
Ka = Ka1 * Ka2 * Ka3
<h3>What is the Ka?</h3>
The Ka is defined as the acid dissociation constant of a solution. Now we have the triprotic acid called phosphoric acid. this implies that we have Ka1, Ka2, and Ka3.
Thus the formula that connects Ka1, Ka2, and Ka3 is the relation;
Ka = Ka1 * Ka2 * Ka3

Answer:
NH3 + CO2 + H2O -> NH4HCO3
This equation is already balanced
4 x 
in dL will be 4 x 
<h3>Conversion from dL to cm^3</h3>
Recall that:
Deci =
Centi = 
Thus, 1 dl = 100 ml
This means that converting from dl to requires multiplying by 
.
Applying this principle, 4 x in dL to will be:
4 x x = 4 x
Therefore, 4 x dl will be 4 x
