Answer:
7.The answer is 2.13 because if u add 3.23 and 4.51 and the answer is 7.74 and u add 2.13 to get 9.87. 3.23 + 4.51 + 2.13 is 9.87
Explanation:
Lewis had proposed that the valence electrons of any substance were arranged around its atoms in a cubic configuration. Later on, this was modified when it was learned that the electrons actually orbit the nucleus, similar to the planets orbiting the sun. Moreover, it is now deduced that the electrons are found in regions, known as electron clouds, and their specific, discrete location at a given point in time can not be determined.
Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm
Explanation :
According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.
Formula used :
where,
= total pressure of gas = 13.6 atm
= partial pressure of helium gas = 1831 torr = 2.41 atm
= partial pressure of argon gas = 997 torr = 1.31 atm
Conversion used: (1 atm = 760 torr)
= partial pressure of nitrogen gas = ?
Now put all the given values in the above formula, we get:
Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm
The ionization energies (kJ/mol) of hydrogen, nitrogen, sodium, chlorine, and fluorine are 1,312, 1,402, 496, 1,256, and 1,681,

Answer: Sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.
Explanation:
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
With increase in atomic size of the atom, there will be less force of attraction between the nucleus and the valence electrons of the atom. Hence, with lesser amount of energy the valence electrons can be removed.
More is the value of ionization energy more it is difficult to remove an electron. Therefore, lesser is the reactivity of element.
Hence, we can conclude that sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.
<span>The
flowers undergo photosynthesis so it is expected to release O2. When you zip
the flower in a plastic bag and placed it in the refrigerator, the plastic bag
will shrink in size. The extra air plus the O2 in the back forms gaseous water.
This gaseous water will slowly liquefy and when placed in the fridge, it will
condense to form water solids.</span>
