Phosphorus has a larger atomic radius than Sulfur
Answer:
Scientific theories are testable and make falsifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy).
A good theory in the theoretical sense is (1) consistent with empirical observations; is (2) precise, (3) parsimonious, (4) explanatorily broad, and (5) falsifiable; and (6) promotes scientific progress (among others; Table 1.1).
A sample of oxygen gas had a volume of 2.50 L at STP.
N<em>itroglycerin decomposes according to the following equation
4 C3H5N309 ---> 12 CO2 + 10 H20 + 6 N2 +O2
The moles of CO2 = 25 /44(molar mass of CO2)= 0.568 moles
the mole ratio of C3H5N3O9 to CO2 IS 4:12 from equation above
therefore the moles of C3H5N3O9=( 0.568 x 4)/12= 0.189 moles
mass of C3H5N3O9=moles x molar mass of C3N5N3O9
That is 0.189 mol x 227 g/mol= 42.903 grams</em>
