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>
A.
As the density of a substance increases, the attraction among its particles increases.
Explanation:
The relationship between density and particle attraction is that as the density of a substance increases, the attraction among its particles increases.
- Density is the function of the mass and volume of body.
- Mass is the amount of particles a substance contains. It is directly related to the density.
- Volume is the amount of space a substance occupies. It is inversely related to the density.
- A substance will have a large volume if it is poorly packed and the attraction between particles is very weak or low.
- Particles that are well packed have high attraction between their particles. This reduces their volume and the density will increase.
