zloy xaker [14]

Answer:

Explanation:

In one of the process, energy is built up from scratch, in the other one, energy is liberated for use by an organism or body.

The first process deals with a metabolic reaction in which energy is liberated:

         C₆H₁₂O₆ + 6O₂  → 6CO₂ + 6H₂O + energy

In the above process, energy is liberated when glucose combines with oxygen. The waste products are carbon dioxide and water. This process liberates heat energy which can be used to do work.

   In the reverse process:

             6CO₂ + 6H₂O   →  C₆H₁₂O₆ + 6O₂

    This process stores energy in carbon chains as chemical energy. It is this energy that is released in the first process.

Therefore, we can see that the first process liberates energy and the reverse process stores energy.

Keith_Richards [23]

Answer:

1) 0.009 61 g C; 2) 0.008 00 mol C

Step-by-step explanation:

You know that you will need a balanced equation with masses, moles, and molar masses, so gather all the information in one place.

M_r:     12.01               44.01

              C  + ½O₂ ⟶ CO₂

m/g:                            0.352

1) <em>Mass of C </em>

Convert grams of CO₂ to grams of C

44.01 g CO₂ = 12.01 g C

    Mass of C = 0.352 g CO₂ × 12.01 g C/44.01 g CO₂

    Mass of C = 0.009 61 g C

2) <em>Moles of C </em>

Convert mass of C to moles of C.

     1 mol C = 12.01 g C

Moles of C = 0.00961 g C × (1 mol C/12.01 g C)

Moles of C = 0.008 00 mol C

All the carbon comes from Compound A, so there are 0.008 00 mol C in Compound A.

molecules.

2. b Carbon is moving into the air and out of the air at the same time

Explanation:

Question 1:

Trees are plants, which are autotrophic organisms i.e. set of organisms that are capable of producing their own food via a process called PHOTOSYNTHESIS. This photosynthetic process produces sugars (glucose) in the presence of SUNLIGHT. According to this question, the sun has been up for several hours, and has been shining on these trees. This means that the trees can take in carbo dioxide (CO2) in order to perform the process of photosynthesis. Also, the number of energy storage molecules in the trees (ATP) will INCREASE.

What can the trees do because they are in sunlight? What does this mean for the ?
