How many moles of carbon dioxide, co2, are produced if 5.87 moles of glucose, c6h12o6, react?
almond37 [142]
The balanced equation for the reaction is as follows
C₆H₁₂O₆ + 6O₃ --> 6CO₂ + 6H₂O
stoichiometry of glucose to CO₂ is 1:6
when 1 mol of glucose reacts - 6 mol of CO₂ are formed 
therefore when 5.87 mol of glucose reacts - 6 x 5.87 mol = 35.22 mol
therefore 35.2 mol of CO₂ is formed

Sample of gas occupies 10.0 L at 50 ˚C. Assuming that the pressure is constant what volume will
scZoUnD [109]

Answer:

<em>20 Liters</em>

Explanation:

If the pressure is supposed to be constant, one of Charles - Gay Lussac's laws can be used to solve the exercise. His statement says that "the volume of the gas is directly proportional to its temperature at constant pressure", mathematically it would be:

\frac{V1}{T1} = \frac{V2}{T2}

Considering T₁ = 50 ° C; V₁ = 10.0 L; and T₂ = 100 ° C, we can calculate the volume V₂ Clearing it from the equation and replacing the values to perform the calculation:

V2= (V1 x T2) / T1  = (10.0 L x  100°C)  / 50 °C = 20 L

Therefore, <em>the gas at 100 ° C will occupy a volume of 20.0 L</em>.

A change in which property of light will have no effect on whether or not the photoelectric effect occurs??? Frequently energy i
slavikrds [6]
Intensity has no affect on whether or not the photoelectric effect occurs.  The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well.  If a frequency of light can't cause the photoelectric effect to happen, no matter what the intensity is, the light can't make it happen.

I hope this helps.  Let me know in the comments if anything is unclear.
