Answer:
The answer is
<h2>3.54 mL</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 9.38 g
density = 2.65 g/cm³
The volume of the quartz is
We have the final answer as
<h3>3.54 mL</h3>Hope this helps you
Answer : The activation energy for the reaction is, 119.7 J
Explanation :
According to the Arrhenius equation,
or,
where,
= rate constant at 271 K
= rate constant at 281 K =
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature = 271 K
= final temperature = 281 K
Now put all the given values in this formula, we get:
Therefore, the activation energy for the reaction is, 119.7 J
