A reaction comprises a reactant and a product. It is said to be in equilibrium when the rates for the forward and reverse reactions are equal. Thus, option D is correct.
What is an equilibrium reaction?An equilibrium reaction is a thermodynamic condition where the reactants and the products are at a stable position even before and after the reaction. They remain fixed and do not vary with the addition of any catalyst.
In the equilibrium position, the reaction rate of the forward (product formation) and reverse (reactant formation) remains the same and is seen in the reversible reactions only.
The amount of the products and the reactant remains constant till the temperature is constant but may vary if the tempearture is varied.
Therefore, the rate of reverse and forward are equal in the equilibrium reaction.

What types of elements- metals,
nonmetals, or metalloids require
the most energy to remove an
electron?
Why do these elements have a higher ionization energy?
Answers
Answer:
Noble gases
Explanation:
The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.
The reason for this difficult is that their electronic configuration confers a stable configuration them.
The ionization energy is the energy required to remove the most loosely held electrons in an atom. Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.Are these correct?? Help please

What will oxygen likely do to complete its outermost shell, based on the Lewis dot diagram shown?
accept electrons
accept some electrons and give up other electrons
move electrons from the inner shell to the outer shell
give up electrons
Answers
Answer:
A. Accept electrons
Explanation:
The octet rule states that 8 electrons stabilizes a molecule. This means that oxygen will try to fill the two empty spots with electrons from other molecules. The Lewis Dot diagram shows these two empty spots with the empty circles at the bottom.
Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Here 'O' accepts electrons. The correct option is A.
The electrical structures of the elements, especially the electron pairings, are reflected in the Lewis dot structures. Lewis structures can be viewed as "electron bookkeeping" and are a helpful approach to condensing some bonding-related information. Each dot in a Lewis dot structure corresponds to 1 electron.
Group 6 member oxygen still requires two additional electrons to complete its outer shell and remain stable. According to the octet rule, an object needs 8 valence electrons in the outer shell to be stable.
Thus the correct option is A.

2. An all natural mosquito repellent

market. One arm is sprayed with the
repellent and one arm is not sprayed
with anything. After 3 hours, the
number of mosquito bites is counted. What is the control group
Answers
Answer:
The arm that was not sprayed with anything
Explanation:
The control group would be the arm that was not sprayed with anything.
The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.
