Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.
In this problem, we have density and we have mass so we can plug into the equation and solve for V.
38.6=270.2/V
<em>*Multiply both sides by V*</em>
38.6V=270.2
<em>*Divide both sides by 38.6*</em>
V=7
The volume of the gold nugget is 7cm3.

The lower the activation energy required for a chemical reaction
Option 1/A (It is the first one)
Answer:
B
Explanation:
For solving this we need a heat balance
By changing the corresponding relations, we have
By cancelling similar factor, we obtain
Which means that the change of temperature in A is twice the change of B
