Answer:

Corn

Explanation:

Being a plant and having chlorophyll in its structures, corn is able to capture sunlight and converting it into chemical energy, through photosynthesis.

Photosynthesis is a process carried out by plants to produce their own food. The plant draws carbon dioxide from the air and energy from the sun. Through this process, the plant produces its own food consisting essentially of glucose.

Briefly, we can say that photosynthesis uses carbon dioxide, water and sunlight (in the form of heat) to produce organic compounds (glucose) and oxygen.

3. How is the equilibrium position of this reaction affected
raketka [301]

Answer:

Explanation: a) Reaction is exothermic because heat is released

                       If temperature is lowered, amount of products is increased,

                      equilibrium transfers to right

b) If pressure decreases, equilibrium transfers to direction in which amount of gas moles is greater, also in left (reactants)

c) If Oxygen is removed, reaction which produces more oxygen is favoured, also balance changes to reactansts (left)

d) Adding product causes equilibrium transfer to left (reactansts)

What volume of ammonia gas, measured at 547.9 mmHg and 27.6oC, is required to produce 8.98 g of ammonium sulfate according to th
Studentka2010 [4]

Answer:

4.65 L of NH₃ is required for the reaction

Explanation:

2NH₃(g)  +  H₂SO₄(aq)  → (NH₄)₂SO₄(s)

We determine the ammonium sulfate's moles that have been formed.

8.98 g . 1mol / 132.06 g = 0.068 moles

Now, we propose this rule of three:

1 mol of ammonium sulfate can be produced by 2 moles of ammonia

Therefore, 0.068 moles of salt were produced by (0.068 . 29) / 1 = 0.136 moles of NH₃. We apply the Ideal Gases Law, to determine the volume.

Firstly we do unit's conversions:

27.6°C +273 =  300.6 K

547.9 mmHg . 1 atm / 760 mmHg = 0.721 atm

V = ( n . R . T ) / P → (0.136 mol . 0.082 L.atm/mol.K . 300.6K) / 0.721 atm

V = 4.65 L
