I am just answering so u can mark the other guy brainliest
When Δ H > 0 that means this is an endothermic reaction, and we can assume heat as one of the reactants. SO when the temperature increases so the reaction will move rightward to decrease the reactants and increase the products and as the products increase it will make the Kw increase also as
Kw = [Products] /[reactants].
So our answer will be: the value of Kw will increase.
Answer:
a. All of the below
Explanation:
Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture.
TLC can be used to analyze a chemical reaction to determine if the reactants have been consumed and a new product has formed. Running a tlc of ferrocene, the acetylferrocene product mixture, and co-spot, when you view the TLC plate under a UV light, you will notice that acetylferrocene product is on the right-most lane, this shows that the reaction appears to be a success: the higher spot of ferrocene has been consumed), and a new product spot is present. From these we can observe that the we can use this to identify the number of products of the reaction, determine if the starting material is still present in the reaction and the elution in a chromatography column of the starting material and products. Therefore, all the choices are correct.
<u>Answer:</u>
For 1: The correct answer is Option D.
For 2: The correct answer is Option A.
<u>Explanation:</u>
Polar molecules are defined as the of molecules, in which two atoms that combine must be of different element and therefore can create a dipole. For a dipole, there must be a difference in electronegativity and that is achieved when two atoms of different electronegativity combine. The negative dipole or charge is created on the electronegative atom and positive dipole or charge is created on the electropositive atom.
Thus, the correct answer is option D.
Non-polar molecules are defined as the molecules which are formed when two atoms of same element combine, so that a dipole cannot be created. When there is no dipole, there will be no difference in electronegativity and this is achieved when two atoms of same electronegativities combine.
Thus, the correct answer is A.
