Which compound most likely contains polar covalent bonds?
marin [14]
I would say water; water is extremely polar, and this is why it can break one of the strongest bonds, ionic bonds. NaCl, as you probably know, is a salt, and dissolves in water. However, the ionic bond holding the Na+ and the Cl- is extremely strong; the boiling point of NaCl is at 1413 degrees celcius (water is at 100 degrees celcius). This means that it requires A LOT of energy to break the bond, but water is able to dissolve and break the bond very easily. It is very polar, so I would answer your question with water. And the bond connecting the H and the O is a covalent bond.

A sample of oxygen gas occupies 3.60 liters at a pressure of 1.00 atm. If temperature is held constant, what will be the volume
evablogger [386]
P1V1=P2V2
(1.00atm)(3.60L)=(2.50atm)V
3.60=(2.50atm)V
3.60/2.50=V
1.44L=V

Fred can create 20 animal balloons every 15 minutes. solve ratio table
DerKrebs [107]

The number of animal balloons created in 15 minutes = 20

The number of animal balloons created in 1 minute = \frac{20}{15}

So, the number of animal balloons created in 6 minutes = \frac{20}{15}\times 6 = 8

And, the number of animal balloons created in 45 minutes = \frac{20}{15}\times 45 = 60

So, the solved ratio table will be:

15.20

6.8

45.60
