Which statement about reversible reactions is correct? At equilibrium, the forward and reverse reactions stop at the appropriate concentrations. At equilibrium, the forward and reverse reactions continue indefinitely. At equilibrium the rate of reaction of products divided by the rate of reaction of reactants equal the equilibrium constant, K.
Answers
The correct answer is At equilibrium the rate of reaction of products divided by the rate of reaction of reactants equal the equilibrium constant, K.
The chemical reactions which occurs in forward direction as well as backward direction under particular conditions is said to be reversible reactions. In these reactions, concentration of reactants and products remain same and both reactions i.e. forward and backward reactions occurs at similar rates.
Equilibrium is the state of reaction in which formation of reactants into products and formation of products into reactants occurs simultaneously at similar rate.
Now, equilibrium constant is equal to the ratio of concentration of the products to the concentration of the reactants.
For example:
Since, rate of reaction is directly proportional to the equilibrium constant i.e.
=
Thus, equilibrium constant is equal to the ratio of rate of reaction of product to the rate of reaction of reactant at equilibrium.

At equilibrium, the forward and reverse reactions continue indefinitely.

B.) Areas at low latitudes have the warmest water because they receive the most direct sunlight.
C.) Areas at high latitudes have the warmest water because they have the longest seasons.
D.) Areas at high latitudes have the warmest water because their days are the longest.
Answers
Areas at low latitudes have the warmest water because they have the least change in temperature throughout the year. Therefore, option A is correct about the relationship between a geographical area and surface water temperature.
What is temperature change with altitudes ?
Ocean temperatures typically range from -2o to 30o C. (28-86o F). Surface water in low latitude regions tends to be the warmest, whereas surface water at the poles is obviously much colder It is worth noting that water on the eastern side of the ocean basins is colder than water on the western side at equivalent latitudes.
Despite the fact that surface water can be quite warm, the majority of the water in the oceans is deeper, colder water, so the average temperature of the entire ocean is around 4° C, which is roughly the temperature inside your refrigerator.
Therefore, the lower altitudes is having warmest water than that at higher altitudes.

Answer:
lawn fertilizer, topsoil, and a diamond necklace
Explanation:
lawn fertilizer and topsoil are coming out of the ground, therefore some amount of minerals will be in them, such as iron added to it to make whatever its going on grow stronger.
a diamond necklace is a jewel that is coming out of the ground. it is categorized as a raw mineral.

The metal loses electrons, and when it becomes Mg2+, it loses two electrons, becoming oxidized. So, the correct option is D.
What is Oxidation reaction?
Initially, the word "oxidation" was used to refer to chemical processes in which a component reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium and oxygen react.
Antoine Lavoisier used the term "oxidation" to describe the reaction of a material with oxygen. The meaning was later expanded to cover additional reactions in which electron are lost, irrespective of whether oxygen was present, after it was realised that the substance loses electrons when it is oxidised.
In the aforementioned example, the metal loses electrons; specifically, it loses two electrons as it changes from Mg+ to Mg2+, getting oxidized.
Therefore, the correct option is D
