A plant is a living organism that uses chlorophyll in the chloroplasts to perform photosynthesis. The chemical equation of photosynthesis is
Sunlight(Photons)+ CO2+2H2O ----->C6H12O6+H2O+O2.(Not balanced) The reactants are carbon dioxide and water. The products are water and glucose with oxygen as a waste product.Photosynthesis can make a plant form a closed cycle as plants need to respire with oxygen which is a waste product of one of their reactions.
<span>Our Earth is structured around the densities of the materials which make it up.One property of density is that it determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth's atmosphere, water, crust, and interior.</span>
Freezing could be a good answer
Explanation:
It is known that the relation between heat energy, specific heat and change in temperature is as follows.
q =
where, q = heat released or absorbed
m = mass of substance
C = specific heat
= change in temperature
It is given that mass is 25.2 g and it is added to 150 ml container so total mass will be (25.2 g + 150 g) = 175.2 g,
is
,
is
, and specific heat of water is 4.184
.
Hence, putting the given values into the above formula as follows.
q =
=
= 
= -8430 J
As, 1 J = 0.001 kJ. Hence, -8430 J will also be equal to -8.43 kJ. The negative sign indicates that heat is being lost.
Thus, we can conclude that heat (kJ) was lost by the solution (surroundings) is 8.43 kJ.
