Answer:
The correct option is: D. Photosynthesis
Explanation:
Photosynthesis is a biological process in green plants by which food such as sugar (like glucose C₆H₁₂O₆), is synthesized from water (H₂O) and carbon dioxide (CO₂) from the atmosphere, in the presence of light energy. This process produces oxygen gas (O₂) as a by-product.
This reaction converts the light energy from the sun to chemical energy.
The reaction involved is: 6 CO₂ (g) + 6 H₂O + light → C₆H₁₂O₆ (s) + 6 O₂ (g)
Photosynthesis is the only process among the given options, that produces oxygen gas.
b. Products are favored over reactants in the reaction.
c. Reactants are favored over products in the reaction.
d. All of the reactants have turned into products in the reaction.
If Keq equals 1, this means the reaction is at equilibrium and neither the reactants nor the products are favored. The concentrations of both remain constant over time.
When Keq = 1, it implies that the reaction is at equilibrium and neither the reactants nor the products are favored in the reaction. So, the correct answer to your question is option a: Products and reactants are equally favored in the reaction.
In this situation, the concentrations of products and reactants remain constant over time because the rate of the forward reaction equals the rate of the reverse reaction.

For a chemical equilibrium, Keq = 1 indicates that neither reactants nor products are favored; rather, they are present in roughly equal amounts at equilibrium. So the correct answer is Option C.
If Keq = 1 for a chemical equilibrium, it means that products and reactants are equally favored in the reaction. In other words, neither the reactants nor the products are favored when the reaction reaches equilibrium. Equilibrium constants help us understand the extent to which a reaction occurs. When Keq is greater than 1, the concentration of products at equilibrium is greater than the concentration of reactants, suggesting a product-favored reaction. Conversely, when Keq is less than 1, the concentration of reactants is higher, indicating a reactant-favored reaction. When Keq is equal to 1, it implies that the concentrations of reactants and products are roughly equal at equilibrium, reflecting a state of balance in the chemical system.

Simply put, a system is an organized collection of parts (or subsystems) that are highly integrated to accomplish an overall goal. The system has various inputs, which go through certain processes to produce certain outputs, which together, accomplish the overall desired goal for the system. A system is a collection of elements or components that are organized for a common purpose. The word sometimes describes the organization or plan itself (and is similar in meaning to method, as in "I have my own little system") and sometimes describes the parts in the system (as in "computer system"). A system is a group of interacting or interrelated entities that form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory. The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole concept made of several parts or members, system", literary "composition".
Answer: Yes.
Explanation:
A white dwarf is the last "stage" for low- and medium-mass stars, it is what stars become after they have exhausted their fuel. They are verydense stars as they are the remaining core of stars. They're typically the size of a regular planet. White dwarves are not the type of stars we usually think of, but they are still stars.
b. -115.6 kcal
c. -173.4 kcal
d. -231.2 kcal
e. -462.4 kcal
According to Gay -Lussac's law, the pressure of the can if it is heated to 1270°C is 4295.53 mm Hg.
It is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.
The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .If a graph of pressure versus temperature is plotted it is a straight line which passes through the origin .
The equation is given as, P₁/T₁=P₂/T₂
On substitution of values as ,P₁=760 mm Hg,T₁=273 K,T₂=1543 K
P₂=1543×760/273=4295.53 mm Hg.
Thus, the pressure of gas is 4295.53 mm Hg if it is heated up to 1270°C.
