Answer:
structures B and C are: enantiomer pair.
Explanation:
Attached below are the structures of all possible Isomers
structures B and C under solution 3 are enantiomer pair. <em>this is because they posses the same connectivity but exhibit opposite three dimensional shapes .</em>
Answer:
And since there is a frictional force acting upon the rotating blades of the fan due to the air, the speed of the fan blades ceases and ultimately comes to halt. Thus here, air friction is the external force which makes the fan blades to stop after sometime, otherwise it would have never stopped rotating :P.
Explanation:
Explanation:
In the following reaction;
aA+bB⇌cC+dD
A and B are the reactants while C and D are the products.
a, b, c and d are regarded as coefficients.
The dependence of the reaction on the concentration of the reactants is given by the rate law.
This is given by;
rate= k [A]^m [B]^n
where
K = Rate constant. Constant for the reaction at that temperature.
m = order of reeaction with respect to A
n = order of reaction with repsect to B
Overall order of reaction is given by m + n
I have no idea but if anyone is seeing this PLEASE ANSWER MY WUESTIONS ON MY PAGE i will give you the brainliest
