Answer:
while atoms form together, they percentage their outermost electrons to create more sustainable strength states. This sharing bonds the atoms into an ionic shape or a molecule

<u>Answer:</u> The new pressure of CO is 0.09 atm
<u>Explanation:</u>
For the given chemical reaction:
The expression of 
for above equation follows:
.......(1)
We are given:
Putting values in above equation, we get:
Addition pressure of chlorine added = 0.39 atm
Now, the equilibrium is re-established:
Initial: 0.26 0.15 0.66
At eqllm: 0.26-x 0.54 0.66+x
Putting values in expression 1, we get:
So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm
Hence, the new pressure of CO is 0.09 atm
Benzene
- Benzene has low density than the water itself of about 0.9 g/cm³
Low denisty object than the water usually <u>floats on the water</u>.
Another example: orange peel which floats on water has density of about 0.84 g/cm³

The number of covalent bonds is determined by the number of valence electrons of an element. The number of electrons tells the maximum number of bonds an element allows. In this case, an oxygen atom requires two bonds. So for Sio2, each oxygen atoms are bonded in double bonds to Si. Hence there are two covalent bonds.
