Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation
Daniel [21]

  • The water in the pot becomes hotter as a result of heat transfer.

  • <em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

  • When a pot containing water  is  placed on the stove and  heat is applied with the burner, there is a flow of heat from the burner to the water.

  • Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water  will be energized as a result of the heat transfer until the boiling point  is  reached.

  • Energy transfer can take place in three form, this could be conduction, radiation or convention.

  • Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>

Photosynthesis can be represented by6CO2(g)+6H2O(l)⇌C6H12O6(s)+6O2(g)Which of the following will be false when the photosynthesi
denis-greek [22]

Answer:

The concentration of O2 will begin decreasing and The concentrations of CO2 and O2 will be equal.

Explanation:

Equilibrium occurs when the velocity of the formation of the products it's equal to the velocity of the formation of the reactants, thus the concentrations of the compounds remain constant.

Analyzing the information and the reaction given, we can notice that in equilibrium the rate (velocity) of formation of O2 (product) is equal to the rate of formation of CO2 (reactant).

As the CO2 and H2O are placed in the reaction, the Le Chateliêr's principle states that the equilibrium must shift to reestablish the equilibrium, thus, they must be consumed, and the concentration of O2 must increase.

As state above, in equilibrium, the concentrations didn't change, thus, the concentrations of CO2 and O2 will not change.

The concentrations of CO2 and O2 depends on the rate of the reaction and the initial quantities presented, so it's not possible to affirm they'll be equal.
