I’m not sure what you’re asking but- halogens are among the most active nonmetals due to their electron configuration and number of valence electrons.
Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid. The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0.1oC. The melting point of solid oxygen, for example, is -218.4o<span>C.</span>
<u>Answer:</u> The amount of carbon dioxide formed in the reaction is 47.48 grams
<u>Explanation:</u>
For the given chemical equation:

To calculate the actual yield of carbon dioxide, we use the equation:

Percentage yield of carbon dioxide = 83 %
Theoretical yield of carbon dioxide = 1.30 moles
Putting values in above equation, we get:

To calculate the number of moles, we use the equation:

Molar mass of carbon dioxide = 44 g/mol
Moles of carbon dioxide = 1.079 moles
Putting values in above equation, we get:

Hence, the amount of carbon dioxide formed in the reaction is 47.48 grams
It is important because if the sample size is smaller, outliers could skew the data more than if it was large.
