The balanced equation is
<span>2 C6H6 +15 O2 = 12 CO2 + 6 H2O </span>
<span>the ratio between C6H6 and CO2 is 2 : 12 </span>
<span>moles CO2 produced = 7.94 x 12 / 2 =47.6</span>
Answer:
Basicity is measured on a scale called the pH scale. On this scale, a pH value of 7 is neutral, and a pH value of more than 7 to 14 shows increasing basicity.
pH value of 7 is weak base and value of 14 means strong base.
mass defect = mass of constituents - mass of atom
N has 7p and 9n
proton mass ~ 1.00728 amu
neutron mass ~ 1.00866 amu
electron mass ~ 0.000549 amu
Nitrogen mass ~ 14.003074 amu
mass defect = (7*1.00728)-(7*1.00866)-(7*0.000549)
- 14.003074
= 0.11235amu
convert to energy, the binding energy = 1.68x10^-11 J
Answer : False, there will be two lithium and one oxygen atoms in a unit molecular structure of lithium oxide.
Explanation:
Electronic configuration of lithium is :

In order to attain stable electronic configuration it will loose an electron and form positively charge cation.

The electronic configuration of oxygen is:

Oxygen being second most electronegative atom requires two electrons to attain noble gas configuration stability and form negatively charge ion with 2- charge.:

When two atom of lithium and oxygen comes together , one electron from each lithium atom get transferred to an oxygen atom which results in formation of lithium oxide.

Answer:
by using the chromatography you can separate different color
