Why is the cellulose and xylose are the best carbon source for producing beta glucosidase based on muthuvelahudham resesacrh paper?
How many liters of liquid nitrogen are produced when 982.0 L of nitrogen gas is liquefied at 77.36K?
0.015 grams Mg was placed in a 153mL flask. The flask was immersed in a water bath whose temp was 24 Celsius. When 5mLs of 1.0M HCL were injected into the flask the attached pressure sensor rose from 100.3 kpa to 108.7 kpa.
from the plots of the boiling point versus the volume of distillate in either of the fractional distillations of the ethanol-water mixture,what conclusion can you draw about the homogeneity of the distillate?
A hydrocarbon is burnt completely in excess oxygen. it is found that 5.0g of the hydrocarbon gives 14.6g of carbon dioxide and 9.0g of water. knowing that the molecular mass of the hydrocarbon is 30.0 determine the molecular formular of the compound.
