What is the equation of photosynthesis?

1 answer:

8 0

Photosynthesis is the chemical process used in plants to convert energy in the form of sunlight into chemical energy in the form of sugar or other carbohydrates.

General equation:carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + waterCO2 + 2H2A + photons ==> [CH2O] + 2A + H2O

Net equation: Because glucose, a six carbon sugar, is often an intermediate product of photosynthesis, the net equation is frequently written as:carbon dioxide + water + light energy ==> glucose + oxygen + water6CO2 + 12H2O + Light Energy ==> C6H12O6 + 6O2 + 6H2OBalanced equation: The net equation above can be simplified as:6CO2 + 6H2O + Light Energy ==> C6H12O6 + 6O2

What's the answer to this question

Flauer [41]

The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction.

Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction.

Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation.

The answer is C, hope it helps!

3. How does the salinity in water change as you move from inland areas out towards the ocean? Be sure to include the phrase "bra

Len [333]

Answer:

Explanation below.

Explanation:

3. The salinity of water increases as the water moves from the inland area to the ocean. This is because the ocean has high salinity.

Salinity is the amount or concentration of salt in the water.

WAYS BY WHICH ESTUARIES PROTECT THE INLAND AREAS

1. The plant in estuaries prevent shoreline erosion.

2. Protect the inland areas from flooding.

3. Protect the inland areas from storm surges from hurricane.

IMPORTANCE OF ESTUARIES TO INLAND PEOPLE AND WILDLIFE.

1. They provide nesting and feeding habits for many aquatic plants and animals.

2. Provide goals and services that are economically and ecologically indispensable.

3. Prevent shoreline erosion

4. Protect the inland areas from flooding.

IMPACTS OF DREDGING ON FISH LIVING ESTUARIES.

Dredging have negative impacts on the organisms in estuaries. These are

1. Habitat degradation

2. Remobilization of contaminants

3. Increase rate of sedimentation.

4. Increased the concentration of suspended matter.

What ways do enzymatic catalysts increase the rates of reactions? they shift the reaction equilibrium toward the products they d

Elodia [21]

This is a question regarding how enzymes increase the rates of reactions. There are choices and the instructions is to check all that apply.

1. They shift the reaction equilibrium towards the products. 
2. They increase the concentration of the reactants. 
3. They lower the activation energy of the reaction. 
4. They decrease the free energy of a reaction. 
5. They promote the formation of a transition state.

The correct answers in this question are "they lower the activation energy of the reaction" and "they promote the formation of a transition state". Enzymes do not necessarily shift the the reaction equilibrium to the products, as there are reversible enzymatic reactions that can reverse the pathway back to the substrates. They do not increase the concentration of the reactants as the concentration of the reactants is an independent variable in this process. They do not decrease the free energy of activation as this is a constant in every reaction depending on the substrates and the products.

Enzymes do, however, lower the activation energy of the reaction meaning it will take less energy and effort for the substrates to reach the activation energy to transform it to its transition state then to the products. With this said, enzymes promote the formation of a transition state.

Attached is a simplified image on how enzymes work.
