First, we need to calculate the theoretical yield as follows:
The balanced chemical reaction is:
<span>2CHCl3 +2Cl2 ----> 2CCl4 +2HCl
</span>molar mass of CHCl3 = <span>119.378 grams
molar mass of CCl4 = </span>153.823 grams<span>
number of moles = mass / molar mass = 11.9 / 119.378 = 0.0997 moles
From the balanced equation, 2 moles of CHCl3 produce 2 moles of CCl4.
Therefore, 0.0997 moles of CHCl4 will produce 0.0997 moles of CCl4.
number of moles = mass / molar mass
mass (theoretical) = molar mass * number of moles
mass (theoretical) = </span><span>153.823 * 0.0997 = 15.336 grams
Now, we will calculate the percent yield as follows:
% yield = (actual mass / theoretical mass) * 100
% yield = (11.2 / 15.336) * 100 = 73.03%</span>
Answer: C2H6O + 3 O2 > 2 CO2 + 3 H2O
Explanation: Here's how to do balancing chemical equations.
Check first the number of atoms on each individual elements in both the reactant and product side.
C has 2 atoms in the reactant so we will put 2 on CO2. Next inspect H. It has 6 atoms in the reactant and 2 in the product side in H2O. So we will put 3 in H2O so it will have 6 atoms in the product. O in the product side has 7 atoms. Because of 2 CO2 and 3 H2O. While on the reactant side it has 3 atoms. So we will put 3 in O2 so it will have 6 atoms plus one atom of oxygen in C2H6O
Answer:
0.315 atm
Explanation:
PV = nRT
P(96.2) = (1.24)(0.08206)(25 + 273)
P = 0.315 atm
Answer:
B. high humidity, cold air temperature, and high air pressure
Explanation:
The Golden Gate bridge is covered in fog and fog needs high humidity cold air and high pressure to form.
