Answer:
Total pressure 5.875 atm
Explanation:
The equation for above decomposition is
rate constant
Half life
Initial pressure
Pressure after 3572 min = P
According to first order kinematics
solving for P we get
P = 2.35 atm
initial 4.70 0 0
change -2x +2x +x
final 4.70 -2x 2x x
pressure of after first half life = 2.35 = 4.70 - 2x
x = 1.175
pressure of after first half life = 2x = 2(1.175) = 2.35 ATM
Total pressure = 2.35 + 2.35 + 1.175
= 5.875 atm
Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is .
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
