You have to do a report :
\frac{E_f}{E_i} =  \frac{47,5}{125} = 0,38

So the truck efficiency is 38%.

All of the statements describe hydrogen bonds EXCEPT: a. Hydrogen bonds account for the anomalously high boiling point of water.
Mamont248 [21]

Answer:

The correct option is e

Explanation:

Hydrogen bond is an intermolecular interaction/bonding that are formed between an electronegative atom (such as nitrogen, oxygen and fluorine) and a hydrogen atom. They are weak intermolecular bonds compared to covalent bonds but account for the high boiling point of water because of the strong hydrogen bond presence between the water molecules. Water molecules form hydrogen bonds between each other; since an oxygen atom (in a water molecule) has two lone pairs on it's outermost shell, it forms an hydrogen bond with two hydrogen atoms of other water molecule. Due to the fluidity of liquid water molecules, hydrogen bonds keep getting broken (although recreated/formed almost immediately), hence, individual hydrogen bonds in liquid water does not exist for long.

In the explanation above, it was stated that the strength of the hydrogen bond in water is the reason for it's high boiling point. The atoms in a water molecule are bent NOT linear hence the strength of hydrogen bond does not depend on the linearity of the atoms involved in the bond.

fomenos

Answer:

He assumed wrongly

Explanation:

It happened this way because the person assumed wrongly.

Most other compounds have the same physical appearance as water especially when in liquid form.

  • This can be a very tricky one in the laboratory.
  • The sense of taste is not the best way to fathom what a particular compound is made up of.
  • This is the reason why this student or person faced this sort of problem.
  • Water has different properties that can be tested for using simple techniques in the laboratory.
