In this reaction the products have less potential energy than the reactants.

A scheme of a chemical reaction. The reactants are two molecules, one of which consists of A and B, and the other consists of C and D.

The products are two molecules, one of which consists of A and C, and the other consists of B and D.

The energy of molecules AB and CD is higher than the energy of molecules AC and BD.

In this reaction heat has been released to the environmen.

Question 8 1.2 pts an atom of bromine has a mass about four times greater than that of an atom of neon. which choice makes the c
Scorpion4ik [409]
Neon = app. 20.1795 g/mol 
<span>Bromine = app. 79.904 g/mol </span>
<span>-----> 79.904 g/mol / 20.1795 g/mol = 3.96 (Close to 4) </span>

<span>Using Moles In 1000 g </span>

<span>1000 g / 20.1795 g/mol = app. 49.555 mol of Ne </span>
<span>1000 g / 79.904 g/mol = app. 12.515 mol of Br </span>
<span>-----> 49.555 mol / 12.515 mol = 3.96 (Close to 4) </span>

<span>Using Avogadro's Number </span>

<span>49.555 mol x 6.022x10^23 atoms = app. 2.984x10^25 atoms of Ne </span>
<span>12.515 mol x 6.022x10^23 atoms = app. 7.537x10^24 atoms of Br </span>
<span>-----> 2.984x10^25 / 7.537x10^24 = 3.96 (Close to 4) </span>

<span>So no matter how you look at it or calculate it, the answer is always the same. </span>

<span>I hope it helps!</span>
