How does the reaction affect oxygen atoms?
Answers
The oxygen atoms react according to the kind of reaction it undergoes. Mostly, O2 is present in combustion reactions. For example, combustion of carbon:
C + O2 ---> CO2

Barium (Ba) has the lowest first ionization energy among the given elements of group 2. Therefore, option (4) is correct.
What is ionization energy?
The ionization energy is the minimum amount of energy that is required to knock out an electron in a gaseous atom or ion. Ionization energy can also be used to estimate the strength of chemical bonds and is measured in units of electronvolts or kJ/mol.
Alkaline earth elements can lose both valence electrons to attain a noble gas configuration. So, these elements have two ionization energies. 1st ionization energy of alkaline earth metals is the energy required to remove the first electron from the neutral atom.
With increasing atomic size down the group, the valence electron gets shielded by the inner electrons. So they can easily be removed with less energy. Hence the first ionization energy of group 2 elements decreases with an increase in the atomic number or atomic size.
Therefore, Barium has the lowest first ionization energy.

Answer:
The partial pressure of nitrogen is 0.402 atm.
Explanation:
Given data:
Number of moles of helium = 1 mol
Number of moles of nitrogen = 2 mol
Total pressure of mixture = 0.60 atm
Partial pressure of nitrogen = ?
Solution:
First of all we will calculate the mole fraction of nitrogen.
mole fraction of nitrogen = moles of nitrogen / total number of moles
mole fraction of nitrogen = 2 mol / 3 mol = 0.67
Partial pressure of nitrogen:
P₁ = [ n₁ /n(t)] × Pt
P₁ = 0.67 × 0.60 atm
P₁ = 0.402 atm
Final answer:
To find the partial pressure of nitrogen in a mixture, calculate the mole fraction of nitrogen and multiply it by the total pressure of the mixture. In this case, the partial pressure of nitrogen is 0.40 atm.
Explanation:
The question is about determining the partial pressure of nitrogen in a mixture of helium and nitrogen based on Dalton's Law of Partial Pressures. First, we find the mole fraction of nitrogen, which is the ratio of moles of nitrogen to the total moles in the mixture. In this scenario, the mole fraction (XN2) is 2 moles of nitrogen divided by the total moles (1 mole of helium + 2 moles of nitrogen), which equals 2/3.
Then we use Dalton's Law, which states that the partial pressure of nitrogen (PN2) can be found by multiplying the mole fraction by the total pressure of the mixture. Therefore, the partial pressure of nitrogen is 0.60 atm (total pressure) multiplied by 2/3 (mole fraction of nitrogen), yielding a partial pressure for nitrogen of 0.40 atm.
