Answer:
A. The equilibrium will shift towards the right, towards the formation of products
B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products
C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction.
Explanation:
The given reaction is an exothermic reaction as it requires the addition of extra energy of about 52.4KJ in the form of heat for the reaction to proceed towards product formation.
According to L' Chtler principle, when an external constraint is applied to A given system in equilibrium, equilibrium position will shift so as to annul the effect ofnthe constraint imposed on the system.
Therefore, the answers tonthe questions above are given below as follows :
A. The equilibrium will shift towards the right, towards the formation of products in order to remove the effect of the additional heat since the forward reaction is endothermic.
B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products .
C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction as the equilibrium will shift towards the right; formation of products.
Answer:
1.68 M
Explanation:
Molar mass (KNO3)= 101.1 g/mol
89g KNO3* 1mol/101.1 g = 89/101.1 mol
(89/101.1 mol)/0.525 L= 1.68 mol/L = 1.68 M
It’s molecular shape.
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.
Answer: C
Explanation:
C just because the other choices dont really make sense. They use these fibers as a way to see what clothes, shoe strings, carpets, etc was there it help identify a person at the scene. Hope this helps!!
