The observation in the illustration remains in accordance with the law of conservation of mass assuming that moisture is present in the container.
<h3>What is the law of conservation of mass?</h3>The law state that mass can neither be created nor destroyed. However, mass can be converted from one form to another.
In this case, the ion was placed in a container of pure oxygen. Assuming that moisture is present, iron reacts with oxygen to form rust according to the following equation:
The rust formed will weigh more than the initial weight of the iron.
Without the presence of moisture, one can effectively conclude that the observation violates the law of conservation of mass.

Answer:1.
2. The rate constant (k) for the reaction is
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
x = order with respect to
y = order with respect to
n = x+y= Total order
1. a) From trial 1: (1)
From trial 2: (2)
Dividing 2 by 1 :
therefore x=1.
b) From trial 2: (3)
From trial 3: (4)
Dividing 4 by 3:
therefore
2. to find rate constant using trial 1:
