Explanation:
N2O4(g) <----------> 2NO2(g)
Before proceeding,
A chemical equilibrium can be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
Statement 1.
This statement is false. Equilibrium is not about equal concentrations but rather zero change in concentration of the reactants and products.
Statement 2.
This statement is True in chemical equilibrium; the forward and reverse reactions occur at equal rates.
Statement 3.
This statement is False. The rate constant for the forward reaction is not equal to the rate constant of the reverse reaction.
Statement 4.
The concentration of NO2 divided by the concentration of N2O4 is NOT equal to a constant. To obtain a constant value irregardless of the concentrations, the concentration of NO2 must be squared. This comes from the stoichiometry of the reaction
Kc= [NO2]2 / [N2O4]
This statement is false.
Because the amount of hydrogens all depends on the valence electrons
B Phytoplankton - Zooplankton - Arctic cod - Ringed sal
Explanation:
The food chain that describes the path through which energy takes will be phytoplankton-zooplankton-Arctic cod-Ringed sal. Energy moves in the ecosystem from producers to primary consumers then secondary and tertiary consumers.
- Autotrophs are those organisms that manufacture their own food. The use chemical substances from the environment to produce their nourishment which serves as the source of energy for the whole ecosystem too.
- Autotrophs are the producers in any ecosystem and they are usually the plants.
- The phytoplankton is an autotroph.
- Next up are the primary consumers that takes up the produced food by the autotrophs for their own nourishment. In the chain above, the Zooplankton is the primary consumer.
- The secondary consumer that feeds on the zooplankton is the Arctic cod.
- The tertiary consumer is the Ringed Sal which feeds directly on the Arctic cod.

Answer: Purple
Explanation: It is impossible to land on purple because there isn't an option for it. You can't land on it if it's not a color on the spinner.
