Answer:
4104 Coulombs
Explanation:
charge = time(sec) *current
25*60 =1500+20=1520
2.7A * 1520 sec =4104
4104 C
Density = Mass/Volume
d= 5 / 4.5
What's the difference between rocks and minerals?A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by a geological processes. A rock is an aggregate of one or more minerals where as a rock may also include organic remains and mineraloids.
I hope this helps
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
