Answer:

We will have 6.49 grams of glucose

Explanation:

Step 1: Data given

water = H2O

carbon dioxide = CO2

glucose = C6H12O6

oxygen = O2

mass of carbon dioxide (CO2) = 9.51 grams

Molar mass of CO2 = 44.01 g/mol

Molar mass of glucose = 180.156 g/mol

Step 2: The balanced equation

6CO2 + 6H2O → C6H12O6 + 6O2

Step 3: Calculate moles CO2

Moles CO2 = mass CO2 / molar mass CO2

Moles CO2 = 9.51 grams / 44.01 g/mol

Moles CO2 = 0.216 moles

Step 4: Calculate moles glucose

For 6 moles CO2 we need 6 moles H2O to produce 1 mol glucose and 6 moles O2

For 0.216 moles CO2 we'll have 0.216/6 = 0.036 moles glucose

Step 5: Calculate mass glucose

Mass glucose = moles glucose * molar mass glucose

Mass glucose = 0.036 moles * 180.156 g/mol

Mass glucose = 6.49 grams

We will have 6.49 grams of glucose

Answer:

6.49g

Explanation:

Let's consider the balanced reaction for photosynthesis.

6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂

We can establish the following relations:

  • 1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
  • The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
  • 1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.

The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

9.51gCO_2 \times \frac{1molCO_2}{44.01gCO_2}  \times \frac{1molGlucose}{6molCO_2}  \times \frac{180.16gGlucose}{1molGlucose} = 6.49g Glucose

A scientist is studying a shock wave from an earthquake. What kind of wave is being studying?
Naily [24]

Answer:

A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.

Explanation:

The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.

How many electrons does carbon lack in its outer shell? biochemistry
tekilochka [14]
A neutral carbon doesn't lack any electrons. It has exactly the same number of electrons as it has neutrons.
However, it has four electrons in its outer shell in comparison with eight electrons for a noble gas.
In that sense, it needs four electrons to complete its second shell.<span />
