Atomic radius of copper atom (r)= 128 pm
volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14 * 128^3
volume = 8780076.373 pm^3
Answer:
Explanation:
To calculate the heat of reaction we need to determine:
- The heat produced
- The moles of Zn that reacted
<u>Moles of zinc (Zn)</u>
It says that the 0.103 g reacted completely, knowing that the Zn molecular weight is 65.4 g/mol:
<u>Heat released by the reaction</u>
The solution goes from 22.5 °C to 23.7°C:
<u>Heat of reaction</u>
I don’t know if this works
Answer:
Methyl pentanoate.
Explanation:
Hello there!
In this case, according to the given information, we can see the correct structure will be:
O
||
CH3CH2CH2CH2COCH3
Which matches with the structure of an ester due to the -COO- functional group. In such a case, the first part of the name is in function of the right side of the ester, in this case, methyl, followed by the left side, pentanoate, as it has five carbon atoms and is an ester (similar to an inorganic salt, but organic) and therefore, the name will be methyl pentanoate.
