Answer:

This is a specific type of dipole-dipole force is known as H<u><em>ydrogen bonding.</em></u>

Explanation:

Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom attached with an electronegative atom( like : O, N and F) and lone pairs of electrons on an neighboring atoms.

Generally this type of bonding is observed where atoms like nitrogen , oxygen, fluorine attached to another molecule are present in neighbors of a hydrogen atom attached to other molecule. This bonding arises due to the interaction between the  developed partial positive and negative charges on the hydrogen and electronegative atoms.

Question 1 A student made measurements on some electrochemical cells and calculated three quantities: The standard reaction free
Zinaida [17]

Answer:

Explanation:

for spontaneous reaction,

ΔG is negative

K>1

E > 0

cell A:

ΔG and EO suggests that reaction is spontaneous. But K is less than 1.

Hence K is wrong

cell B:

ΔG and EO suggests that reaction is non spontaneous .But K is greater than 1.

Hence K is wrong

cell C:

E and K suggest than reaction is non spontaneous but ΔG suggest that reaction is spontaneous.

Hence ΔG is wrong

Use logarithmic properties to solve the following equation log3 5x+ log3 7= 4 leave your answer in fraction form please
Salsk061 [2.6K]

Explanation:

Adding logs of same base is equivalent to multiplying the arguments. You get:

log_{3}(35x)  = 4

Use the definition of the log to turn this into an exponential function:

{3}^{4}  = 35x

81 = 35x

x =  \frac{81}{35}
