Based on the nature of chemical equilibrium, the system reached equilibrium first at the time T2.
<h3>What is chemical equilibrium?</h3>
Chemical equilibrium refers to the state of a reversible chemical reaction in which the rate of forward reaction for the the formation is equal to the rate of backward reaction for the formation of reactants.
In the table of the decomposition reaction given above, the system reached equilibrium first at the time T2 when the concentration of the reactant and products were the same.

Answer:
D.
Explanation:
The hypothesis was that speed would increase with the addition of mass from passengers. The data shows that when passengers/mass are added, speed decreases.
Answer:
Physical properties increasing atomic number
Explanation:
The modern periodic table is arranged by the increasing atomic number and for that reason elements with similar chemical properties are in the same group
It is incorrect because it should have a total of eight electrons with two electrons between each H and O
<h3>Further explanation
</h3>
Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound
This bonding usually occurs in covalent bonds
Valence electrons are electrons used in a chemical bond
The main group elements usually have valence electron configurations in the ns and np subshells, While the transition elements in the subshells (n-1) d and ns.
Element O has 6 valence electrons
Element H has 1 valence electron
To achieve stability, the element O needs 2 more electrons which are obtained from 2 electrons from the H element, while the H element needs 1 electron to be stable
So that a covalent bond is formed
Answer:
the concetration wouldent be equal and the ph would be off than the expected ph and it would have all ready passed the hydration point
