What energy convertion happens when green plants use energy from the sun to make sugar?

2 answers:

8 0

The energy conversion happening here is known as photosynthesis. Photosynthesis is a process where the leaves of a plant absorb water and carbon dioxide, then, using light energy from the sun, convert that into oxygen and sugar.

Answer:

Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.

At high pressures how does the volume of a real gas compare with the volume of an ideal gas under the same conditions and why

malfutka [58]

Answer: No, at high pressures, volume of a real gas does not compare with the volume of an ideal gas under the same conditions.

Reason:
For an ideal gas, there should not be any intermolecular forces of interaction. However, for real gases there are intermolecular forces of interaction like dipole-dipole and dipole-induced dipole. Further, at high pressures, molecules are close by. Hence, extend of these intermolecular forces is expected to be high. This results in decreases in volume of real gas. Thus, volume of a real gas does not compare with the volume of an ideal gas under the same conditions.

Why are lead compounds harmful to us?

Dominik [7]

Explanation:

Lead can cause effects on the blood, as well as the nervous, immune, renal and cardiovascular systems. ... Exposure to high amounts of lead can cause gastrointestinal symptoms, severely damage the brain and kidneys, and may cause reproductive effects. Large doses of some lead compounds have caused cancer in lab animals.

When 32 grams of aluminum react, the actual yield is 105.5 grams, what is the percent yield?

user100 [1]

Answer:

329.7%

Explanation:

Percent Yield = Actual Yield/ Theoretical Yield x 100%

Percent Yield = 105.5g/32 x 100% = 329.69 ≈ 329.7 %

A certain substance X has a normal freezing point of 5.6 °C and a molal freezing point depression constant Kf-7.78 °C-kg·mol-1.

Harrizon [31]

Answer:

27.60 g urea

Explanation:

The freezing-point depression is expressed by the formula:

ΔT= Kf * m

In this case,

ΔT = 5.6 - (-0.9) = 6.5 °C

Kf = 7.78 °C kg·mol⁻¹

m is the molality of the urea solution in X (mol urea/kg of X)

First we calculate the molality:

6.5 °C = 7.78 °C kg·mol⁻¹ * m

m = 0.84 m

Now we calculate the moles of urea that were dissolved:

550 g X ⇒ 550 / 1000 = 0.550 kg X

0.84 m = mol Urea / 0.550 kg X

mol Urea = 0.46 mol

Finally we calculate the mass of urea, using its molecular weight:

0.46 mol * 60.06 g/mol = 27.60 g urea
