Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0
grandymaker [24]

The given question is incomplete. The complete question is:

Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis. Determine the mass of glucose (C6H1206) produced

Answer: 60.0 g of glucose

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

a) moles of CO_2

\text{Number of moles}=\frac{88.0g}{44g/mol}=2.0moles

b) moles of H_2O

\text{Number of moles}=\frac{64.0g}{18g/mol}=3.5moles

6CO_2+6H_2O\rightarrow C_{6}H_{12}O_6+6O_2

According to stoichiometry :

6 moles of CO_2 require = 6 moles of H_2O

Thus 2.0 moles of CO_2 require=\frac{6}{6}\times 2.0=2.0moles  of H_2O

Thus CO_2 is the limiting reagent as it limits the formation of product.

As 6 moles of CO_2 give =  1 moles of glucose

Thus 2.0 moles of CO_2 give =\frac{1}{6}\times 2.0=0.33moles  of glucose

Mass of glucose = moles\times {\text {Molar mass}}=0.33moles\times 180g/mol=60g

Thus 60.0 g of glucose will be produced from 88.0 g of carbon dioxide and 64.0 g of water

If a gas has a volume of 3.67 L and a pressure of 790 mm Hg, what will the pressure be if the volume is compressed to 2.12 L? Wh
oksian1 [2.3K]

If each gas sample has the same temperature and pressure, which has the greatest volume? Since hydrogen gas has the lowest molar mass of the set, 1 g will have the greatest number of moles and therefore the greatest volume. What is the Ideal Gas Law?

The maximum energy of photo electrons (increases or decreases or remains constant) with increasing frequency and (increases or d
morpeh [17]

Answer:

Increases,  remain constant

Explanation:

In the light spectrum, the photons with a higher frequency (hence smaller wavelengths) have higher energy. The lower the energy the lower the frequency and longer the wavelengths. The intensity of light does not change the energy levels of these photons. The higher the intensity the higher the density of the photoelectrons.
