Explanation:
I can’t see it can you write the problem ?
Answer:
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
75 % is decomposed which means that 0.75 of is decomposed. So,
= 1 - 0.75 = 0.25
t = 60 min
k = 0.023 min⁻¹
Considering the expression for half life as:-
Where, k is rate constant
So,
Answer:
five electrons
Bromine (Z=35), which has 35 electrons, can be found in Period 4, Group VII of the periodic table. Since bromine has 7 valence electrons, the 4s orbital will be completely filled with 2 electrons, and the remaining five electrons will occupy the 4p orbital
