That would be the noble gases. <span />
Answer:
K potassium have least ionization energy among these four
Explanation:
Ionization energy values are given in kilo joule per mole
Ca 590
Ge 762
K 419
Ga 579
From above data we can understand stand K has least and Ge has highest ionization energy
Explanation:
To a reaction to be occured
The formula is
IE is internal energy of reactant and AE is activation energy and TE is threshold energy .
So option D is correct
Answer:
The pressure of the gas inside the plastic bag is 1.971 atm
Explanation:
Since temperature did not change, it means it is constant. This will then be Boyle's law. Thus
P1V1 =P2V2
Where P1 is the initial pressure = 10.2 ATM, P2 is the final pressure which is to be calculated.
V1 is the initial volume = 800.0 mL and V2 is the final volume of the gas = 4.14 L
From the formula,
P2 = P1V1/V2
= 10.2×800÷4.14
= 1.971 atm
