The sample of smoke described above can be described as a heterogeneous mixture. This type of mixture do not have uniform properties and composition. So, getting a certain small sample would not represent the whole mixture since it does not have uniform composition.
Percent yield is expressed as the ratio of the actual yield and the theoretical yield of the reaction multiplied by 100 to get the percent value. The actual yield is usually given in a problem. The theoretical yield is calculated from the reaction. For this problem, it cannot be solved since we cannot obtain the theoretical yield.

Answser: a curved line.
Justification:
Boyle's law states that a constant temperature the volume of a certain amount of gas is inversely related to the pressure:<em> pV = k.</em>
The graph of two inverseley related variables is a curve: as one variable increases the other decresases.
In such a curve for any pair of points it is obeyed Boyle's law: pV = constant, so:
<em> p₁V₁ = p₂V₂ = p₃V₃ = ... = k</em>
Mathematically, the graph represents a hyperbola: as the value of one of the variables increase the other trends to zero, so the curve approaches the axis without touching them.
See the figure attached to visualize the form of the curve.
Answer:
1.175 M
Explanation:
Mass = 32.9 g
Volume = 700.0 mL = 0.7 L
Molarity = ?
The relationship between the quantities is given by;
Molarity = Number of moles / Volume
Number pf moles = Mass /Molar mass
Number of moles = 32.9 / 40 = 0.8225 mol
Molarity = 0.8225 / 0.7 = 1.175 M
