Average velocity is the change in distance divided by the time it takes to travel that distance. so the first one.
Answer: chemical bond
Explanation:
The chemical bond simply refers to the electrostatic attraction that can be found between ions that are oppositely-charged. It should be noted that the chemical bond occurs due to the transfer of electrons that is being found between atoms.
Therefore, based on the question given, the electrostatic attraction that is seen between a positively charged nuclei and the negatively charged electrons which hence allows two atoms to be held together is the chemical bond.
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,
I think because students get confused or forget which elements are diatomic
A decomposition usually is simple and straight forward but many students just don't know which elements should be diatomic and which shouldn't.
