If 3.0g of H20 actually forms what is the percentage yield
Sati [7]
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.

The graph of several pressure-volume readings on a contained gas at constant temperature would be
tigry1 [53]

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.

4) Calculate the molarity of a solution prepared by dissolving 32.9 g of NaOH in enough water to
Dmitriy789 [7]

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
