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,
False, they have a balance between positive and negitive characters. 6 protons, 6 electrons
I think there both energy
The chemical name is carbon. Maybe you meant something else
Answer:
In physical changes no new materials are formed and the particles do not change apart from gaining or losing energy
