J. J Thompson’s atomic model
Answer:
Explanation:
Hello,
In this case, given the mass of the sample and mass of tin we can compute the mass of oxygen via:
Thus, by using the atomic bas of tin and oxygen we can compute their moles:
Next, we need to divide both moles by the moles of oxygen as those are the smallest in order to compute the subscript in the chemical reaction:
Therefore, empirical formula of the oxide should be:
Best regards.
Answer:
The answer is
<h2>686.01 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of zinc = 96.08 cm³
density = 7.14 g/cm³
The mass is
mass = 96.08 × 7.14 = 686.0112
We have the final answer as
<h3>686.01 g</h3>
Hope this helps you
Its important because the temp can either take away or add energy to a substance.
