In the following reaction, 451.4 g of lead reacts with excess oxygen forming 365.0 g of lead(II) oxide. Calculate the percent yi
user100 [1]
Let MM(x) be the molar mass of x.

MM(Pb) : MM(PbO)
=207.21 : 223.20  =  451.4 g : x g

cross multiply and solve for x
x=223.2/207.21*451.4
= 486.23 g

Percentage yield = 365.0/486.23= 0.75067 = 75.07% (rounded to 4 sign. fig.)

In-s [12.5K]

Out of the following given choices;

A. increasing the pH of the salt.

B. increasing the surface area of the salt.

C. increasing the pressure of the salt.

<span>D. increasing the temperature of the salt.</span>

 

The answer is B. When a substance is reduced to smaller sizes, its surface area to volume ratio increases. Therefore crushing barium salts to smaller particles increase the surface area on which it reacts with the acid. This consequently increases the rate of speed of the reaction.
