2 moles of NO3 contains 6 moles of O
Phosphorus 31. because the mass of sulfur 32 minus the number of protons 16 = 16 neutrons and the mass of phosphorus 31 minus the number of protons 15 = 16 neutrons
Final answer: phosphorus 31
Answer:
atoms Ti = 2.193 E23 atoms
Explanation:
- 1 mol ≡ 6.022 E23 atoms
- mm Ti = 47.867 g/mol
⇒ atoms Ti = (20.9 g Ti)×(mol/47.867 g)×(6.022 E23 atoms/mol)
⇒ atoms Ti = 2.193 E23 atoms
Explanation:
Atoms of the same element that differ in their numbers of neutrons are called isotopes. ... Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Answer:
Chemical reaction
Explanation:
