Answer:
<h2>6.41 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual density = 7.80 g/cm³
error = 7.30 - 7.80 = 0.5
We have

We have the final answer as
<h3>6.41 %</h3>

Explanation:
Mg+NaF. NaF+Mg
are use sure about the question
A because for example in n=4 we have all of these sub levels 4s is completed sooner than 4p and so
Since Qp>Kp , the reaction is not at equilibrium.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant shows the extent to which reactants are converted into products.
Now we have to obtain the Qp as follows;
Qp =[CH3OH]/[CO] [H2]^2
Qp = 0.265/(0.265) (0.265)^2
Qp = 14.2
Now we know that Kp = 6.09×10−3, Since Qp>Kp , the reaction is not at equilibrium.
