The standard entropy change of the reaction is negative .
Given ,
For the reaction depicted in the molecular scenes , X is red and Y is green .
through observing the scenes , the balanced chemical equation of the scenes is given by ,
3X2 + 9Y2 → 6XY3
The reaction representation indicates that there are 12 reactant molecules which gives 6 product molecules .here the degree of disorderness of molecules decreases from reactants to the products and thus the entropy decreases during the reaction .
The standard entropy of the reaction is given by ,
ΔS°rxn = sum of the S°(products ) - sum of the S°(reactants )
Therefore , the sign of the entropy change of the reaction is negative .
<h3>What is a balance chemical reaction ?</h3>
A balanced chemical reaction is a type of reaction which include the reactants and products in same amount i.e. the no of mole on both side of the reaction is remains same or balanced .

Answer:
16.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of He = 0.750 mole
Volume of He =?
Recall:
1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.
Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:
1 mole of He occupied 22.4 L at STP.
Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.
Thus, 0.750 mole of He is equivalent to 16.8 L
When 1-bromo propane is reacted with sodium metal, the propane and sodium bromide are formed.
- Propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal.
- The Bromine which is present in the 2-bromopropane is removed through hydrogenation and combines with the sodium metal which results in the production of propane and sodium bromide.
- So we can conclude that propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal.
