Answer:
Chemical Symbols
Explanation:
Im not positive on this one so dont rely on me lol
The mass of is 0.185 g.
To calculate the number of moles first calculate the molar mass of .
Molar mass of nitrogen and oxygen is 14 g/mol and 16 g/mol respectively
Thus,
Now, number of moles can be calculated from mass and molar mass as follows:
Therefore, number of moles of 0.185 g is 0.0042 mol.
Answer:
Kyanite (Al2SiO5) - silicate
Ilmenite (FeTiO3) - Oxides
Rhodochrosite (MnCO3) - carbonate
Celestite (SrSO4) - sulphate
Chalcocite (Cu2S) - sulphide
Explanation:
Minerals are classified according to their chemical composition. For example those that hve the CO32- ion are called carbonates and those with the SO42- ion are called sulphates while the ones with S2- ion are called sulphides
Protons and neutrons are found inside the nucleus
That would be phosphorus. It’s electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^3
