What name should be used for the ionic compound KOH?

Equal volumes of two equimolar solutions of reactants a and b are mixed, and the reaction a+b→c occurs. at the end of 1h, a is 9

SVEN [57.7K]

a) First order in A and zero order in B

ln [A] = (ln 0.1) (2) + ln Ao = ln 0.01 + ln Ao = ln 0.01 Ao = 1.0% of A will remain

b) First order in A and first order in B

1/[A] – 1/[A]0= kt where t+=1 and k=9

[A]/[A]=1/19=0.053=5.3%

c) Zero order in both A and B

[A]0-[A] = kt

Then at 2 hours [A]=0 All of it has reacted.

Which compound is most likely to follow second-order kinetics in a substitution reaction? (ch3)2chbr ch3ch2br (ch3)3cch2br ch3br

Inga [223]

Substitution reaction monitors second-order kinetics; that is, the degree of the reaction hinge on on the concentration of two first-order reactants. In the circumstance of bimolecular nucleophilic substitution, these two reactants are the nucleophile and the haloalkane. So for this problem, the answer is ch3br.

Can someone please help me

Alona [7]

Answer:

Potassium iodide increases the decomposition rate of hydrogen peroxide.

Explanation:

Potassium iodide increases the decomposition rate of hydrogen peroxide because potassium iodide act as a catalyst. A catalyst speed up the process of chemical reaction without reacting with the molecules present in reaction. If the potassium iodide is not present as a catalyst for the decomposition of hydrogen peroxide then the decomposition of hydrogen peroxide takes too much time because the catalyst is absent that speed up the reaction.

How many polar bonds are found in this molecule

Law Incorporation [45]

A bond is non polar if it is between same atoms and polar if it is between different atoms.

Same atoms are like two dogs of same strength pulling a bone towards towards each other. But when it’s different atoms it’s like a big dog and small dog then the bone is more towards bigger dog. So it’s the same way in bonds.

Bonds are made up of electrons, when the more stronger pulling atom is present than other the electrons are more towards it and as a result we have polar bond. There is development of a kind of a negative pole and a positive pole.

The stronger atom has electrons towards itself so it has a little more negative charge while the other atom has positive charge. This makes bond polar.

So just look for bond between two different atoms, it would be polar.

Look at the pic below to see the answer.

Marked with green is bond between same atoms... one carbon and another carbon so it is not polar and test marked with blue are polar.

Well the answer should have been 10 but since the bonds at 3 and 8 are two of same type we count only one of them.

The answer is 8... well the answer should be 10 otherwise... discuss it with ur teacher
