Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is,
6CO₂ + 6H₂O + light energy --> C₆H₁₂O₆ + 6O₂
This process occurs in the chloroplasts of the plant, using light energy to split water molecules into oxygen and hydrogen. The oxygen is released into the atmosphere while the hydrogen combines with carbon dioxide to form glucose. This glucose is then converted into other compounds, such as cellulose, which the plant uses for energy.
The equation of photosynthesis shows how plants use carbon dioxide and water, combined with light energy from the sun, to produce glucose and oxygen. This process is crucial for life on Earth, as it is the primary way that plants and other photosynthetic organisms convert carbon dioxide into oxygen.
The process of photosynthesis is closely related to the carbon cycle, as it helps to keep the levels of CO₂ in the atmosphere balanced. Photosynthesis removes carbon from the atmosphere and stores it in the form of organic compounds, such as glucose.
As plants use glucose for energy, they release some of this carbon back into the atmosphere in the form of CO₂. This process helps to maintain a steady balance of CO₂ in the atmosphere, which is crucial for life on Earth.

Answer:
The "particles" of light are called photons and have no mass. In contrast, matter is made up of particles that do have mass. Sound is a little different in that it is the propagation of a pressure wave through a medium of particles. Since it is a wave, it is not considered a form of matter.(scienceline.com)
Explanation: Hope this helps
Answer:
it has 12 carbon atoms and 22 hydrogen atoms and 11 oxygen atoms

Answer:
C15H24O
Explanation:
TO GET THE EMPIRICAL FORMULA, WE NEED TO KNOW THE MASSES AND CONSEQUENTLY THE NUMBER OF MOLES OF EACH OF THE INDIVIDUAL CONSTITUENT ELEMENTS.
FIRSTLY, WE CAN GET THE MASS OF THE CARBON FROM THAT OF THE CARBON IV OXIDE. WE NEED TO KNOW THE NUMBER OF MOLES OF CARBON IV OXIDE GIVEN OFF. THIS CAN BE CALCULATED BY DIVIVDING THE MASS BY THE MOLAR MASS OF CARBON IV OXIDE. THE MOLAR MASS OF CARBON IV OXIDE IS 44G/MOL
<h3>
HENCE, THE NUMBER OF MOLES OF CARBON IV OXIDE IS 4.122/44 WHICH EQUALS 0.094. SINCE THERE IS ONLY ONE ATOM OF CARBON IN CO2 THEN THEY HAVE EQUAL NUMBER OF MOLES AND THUS THE NUMBER OF MOLES OF CARBON IS 0.094. WE CAN THEN PROCEED TO CALCULATE THE MASS OF CO2 PRESENT. THIS CAN BE CALCULATED BY MULTIPLYING THE NUMBER OF MOLES BY THE ATOMIC MASS UNIT. THE ATOMIC MASS UNIT OF CARBON IS 12. HENCE, THE MASS OF CO2 PRESENT IS 12 * 0.094 = 1.128g</h3><h3>
</h3><h3>
WE CAN NOW GET THE MASS OF THE HYDROGEN BY MULTIPLYING THE NUMBER OF MOLES OF WATER BY 2 AND ALSO ITS ATOMIC MASS UNIT</h3><h3>
</h3><h3>
TO GET THE NUMBER OF MOLES OF WATER, WE SIMPLY DIVIDE THE MASS BY THE MOLAR MASS. THE MOLAR MASS OF WATER IS 18g/mol. The NUMBER OF MOLES IS THUS 1.350/18 = 0.075</h3><h3>
</h3><h3>
THE NUMBER OF MOLES OF HYDROGEN IS TWICE THAT OF WATER SINCE IT CONTAINS 2 ATOMS PER MOLECULE OF WATER. ITS NUMBER OF MOLES IS THUS 0.075*2 = 0.15 MOLE</h3><h3>
</h3><h3>
THE MASS OF HYDROGEN IS THUS 0.075 * 2 * 1 = 0.15g</h3><h3>
</h3><h3>WE CAN NOW FIND THE MASS OF OXYGEN BY SUBTRACTING THE MASSES OF HYDROGEN AND CARBON FROM THE TOTAL MASS.</h3><h3 /><h3>MASS OF OXYGEN = 1.376-0.15-1.128 = 0.098g</h3><h3 /><h3>THE NUMBER OF MOLES OF OXYGEN IS THUS 0.098/16 = 0.006125</h3><h3 /><h3>WE CAN NOW USE THE NUMBER OF MOLES TO OBTAIN THE EMPIRICAL FORMULA.</h3><h3 /><h3>WE DO THIS BY DIVIDING EACH BY THE SMALLEST NUMBER OF MOLES WHICH IS THAT OF THE OXYGEN.</h3><h3 /><h3>C = 0.094/0.006125 = 15</h3><h3>H = 0.15/0.006125 = 24</h3><h3>O = 1</h3><h3 /><h3>THE EMPIRICAL FORMULA IS THUS C15H24O</h3>
