When you burn a log in your fireplace you are converting c<span>ellulose into carbon dioxide and water.
</span>
Wood is made from cellulose. When wood burns, cellulose reacts with oxygen from the air and it forms carbon dioxide and water vapor.

The reaction of the combustion of glucose is as follows:

C₆H₁₂O₆ + 6O₂ = 6 CO₂ + 6H₂O
When wood burns, we notice that it slowly disappears because it passes into the mentioned gases. The ash that is created is part of the wood that did not burn.

Charcoal is primarily carbon. what mass of co2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.80 k

Reika [66]

When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g) ΔH = - 393.5 kj/mol
The enthalpy change of the reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj
= 480 × 1/393.5
= 1.2198 moles
1 mole of carbon iv oxide is equal to 44 g
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2

7th grade science , please don’t get the answer from the internet :(

Liula [17]

Answer:

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP$

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

$C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP$

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

$6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2$

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP$

Through what process do all stars produce their energy?

Deffense [45]

nuclear fusion

Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the "proton-proton chain," a sequence of events that transforms four hydrogen atoms into one helium atom.
