Determine the mass of CO2 produced by burning enough carbon (in the form of charcoal) to produce 510 kJ of heat. C(s) O2(g)CO2(g)ΔHrxn393.5k?

The heat produced by burning 1 mol of carbon to form CO2 is 393.5 kJ. To produce 510 kJ of heat, we utilize the ratio of heat produced to calculate the moles of CO2 produced as (510 kJ / 393.5 kJ) mol CO2. The molar mass of CO2 is 44.01 g/mol, so the mass of CO2 produced is (510/393.5) * 44.01 g.


What is the molar extinction coefficient for glucose at 510 nm?

I am not some one of this background and so please correct me if I am wrong. I think molar extinction coefficient will be very less and according to molecular structure of any molecule (bond vibration etc..,) only some wavelengths will have reasonable absorption and for glucose those wavelenghts are 1550-1850 nm; 6450-5400 cm(-1) (first overtone) 2000-2500 nm; 4000-5000 cm(-1) (combination). These are the spectral windows in which glucose has significant absorption.


What wavelength is the peak absorbance of cobalt chloride?

The peak absorbance of cobalt chloride typically occurs at a wavelength around 550-600 nm. This range falls within the green to yellow-green region of the visible spectrum, where cobalt chloride absorbs light most strongly.


Lewis structure for SF2?

the structure is like water but with F where hydrogen should be and S where oxygen should be so its F-S-F but of course its bent. but make sure you don't forget the 2 pair of electron pairs on the S. the angles shrinks by 1 degree give or take


What type of thread is used on the acetylene supply?

Acetylene is typically supplied through a specialized type of thread known as a CGA 510 connection. This thread type ensures a secure and leak-free connection between the acetylene supply tank and the regulator or other equipment being used.
