How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
Knowing that the number of protons of an element is equivalent to its atomic number, it can be determined from the periodic table of elements that this radiosonde is phosphorus. Since the number of its neutrons is 17, it can also be determined that its atomic mass is n + p = 15 + 17 = 32. This means the isotope is phosphorus-32.<span />
SI unit for pressure is Pascal
Answer:
NBr3 has a trigonal pyramidal geometry where the nitrogen atom is bonded to three bromine atoms and has one lone pairs. The individual bonds are polar, as bromine is less electronegative than nitrogen. The overall compound is also polar, as the dipoles do not cancel.
Explanation:
The appropriate answer is c. the solid phase, liquid phase and gas phase of a substance. A phase diagram is used to represent the phase or physical state of a substance at a given temperature or pressure. Pressure is represented on the y axis while temperature is represented on the x axis. Phase diagrams are used in areas such as Physics, Chemistry, Engineering, Mineralogy and Material Science.
