Which equation best represents the process of photosynthesis ? A. 6CO2+12H2O-> light+C6H12O6+6O2+6H2O B.6CO2+12H2O+light->C6H12O6+6O2+6H2O C.C6H12O6+6O2+6H2O+light->6CO2+12H2O D.C6H12O6+6O2+6H2O->light+6CO2+12H2O

Answers

The correct answer is B. The equation that represents the process of photosynthesis is: 6CO2+12H2O+light->C6H12O6+6O2+6H2O. Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product.

Answer: The correct answer is Option B.

Explanation:

Photosynthesis is defined as a process in which a plat uses carbon dioxide reacts with water in the presence of sunlight to produce glucose as a product, oxygen and water as a byproduct.

The chemical equation for this reaction follows:

$6CO_2+12H_2O+\text{light}\rightarrow C_6H_(12)O_6+6O_2+6H_2O$

By Stoichiometry of the reaction:

6 moles of carbon dioxide reacts with 12 moles of water in the presence of light to produce 1 mole of glucose, 6 moles of oxygen and 6 moles of water.

Hence, the correct answer is Option B.

Hydrocarbons are separated from each other by a process called cracking distillation. a. True
b. False

Answers

True, cracking distillation is one process used to break hydrocarbons into smaller and more useful parts. This is achieved by using high temperatures and pressures with a catalyst. The most common catalyst used are the zeolites.

What is true at STP? 1) Temperature is 295 Kelvin.
2) One mole of gas occupies a volume of one liter.
3) Pressure is 1.0 atmosphere.
4) Volume is 2.4 liters

Answers

The correct answer for the question that is being presented above is this one: "3) Pressure is 1.0 atmosphere." STP stand for standard temperature and pressure. The values of STP are 22.4 liters, 1mole, 1.00 atmospheres, and 273 kelvin. Under these conditions, all gases behave ideally or the same.

Which is a characteristic of a nonelectrolyte?A. It does not dissociate or ionize in water.
B. It partially dissociates or ionizes in water.
C. It conducts electricity poorly.
D. It conducts electricity extremely well.

Answers

Answer: Option (A) is the correct answer.

Explanation:

Non-electrolytes are the substances which do not dissociate into a solution or water to form ions.

Since, non-electrolytes do not dissociate into ions. Hence, they do conduct electricity.

Thus, we can conclude that it does not dissociate or ionize in water is a characteristic of a non-electrolyte.

Non-electrolytes are neither partially ionizable nor do they conduct electricity poorly. Therefore, out of the given options, only option (A) is the correct answer.
