Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. ... Current is the effect (voltage being the cause).
<h3>Answer:</h3>
Theoretical Yield = 3.11 g
%age Yield = 86.81 %
<h3>Solution:</h3>
The Balance Chemical Equation is as follow,
C₆H₁₂O + Catalyst → C₆H₁₀ + H₂O + Catalyst
Where;
C₆H₁₂O = Cyclohexanol
C₆H₁₀ = Cyclohexene
Calculating Theoretical Yield:
According to equation,
100.16 g (1 mol) of C₆H₁₂O produces = 82.15 g (1 mol) of C₆H₁₀
So,
3.8 g of C₆H₁₂O will produce = X g of C₆H₁₀
Solving for X,
X = (3.8 g × 82.15 g) ÷ 100.16 g
X = 3.11 g of C₆H₁₀
Theoretical Yield = 3.11 g
Calculating %age Yield:
As,
%age Yield = Actual Yield ÷ Theoretical Yield × 100
So,
%age Yield = 2.7 g ÷ 3.11 g × 100
%age Yield = 86.81 %

Answer:
18.52g
Explanation:
(relative atomic masses: H = 1.01, O = 16.00, Ca = 40.08)
Equation (balanced):
Ca + 2H2O -> Ca(OH)2 +H2
First, calculate the number of moles of 10g calcium
No. of moles of Ca = 10/40.08 = 0.25 mol
Then, calculate the number of moles of 20g water
No of moles of H2O = 1.11 mol
According to the balanced equation, 1 mole of calcium reacts with 2 moles of H2O completely. Therefore, H2O is in excess.
So, 1 mole of calcium reacts with water to form 1 mole of Ca(OH)2 (according to the mole ratio shown in the balanced equation)
Therefore, 0.25 mol of Ca(OH)2 is produced.
Mass of Ca(OH)2 produced = no. of moles x molar mass = 0.25 x (40.08 + 16 + 16 + 1.01 + 1.01) = 18.52g
Good luck!
