Increaseing the pressure will cause the equilibrium to move to the right of the reaction, producing more products than reactants. This is because there is fewer gasseous moles on the right (2 moles) than ...

There is fizzing, because the reaction of any alkali metal with water will produce hydrogen, this gas escapes as fizzing The metal will become smaller and dissapear, because as the reaction continues, the...

Crude oil has lots of molecules with different numbers of carbon atoms in them. A fractional distillation column is used to separate the molecules. It is hottest at the bottom and coolest at the top. Bitu...

Group 1 metals all have one electron in their outer shell. When they react they form positive metal ions by losing this electron. Since there is only one electron to lose, group 1 metals are all extrememe...

The formula mass (Mr) of FeSO4 is the total mass of all the individual elemenets added together. So the Mr of FeSO4 = (1 x Fe) + (1 x S) + (4 x O) = 56 + 32 + 4x16 = 152 To calculate moles, the equation f...
