mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a great...

The collision theory states that when two or more particles have sufficient energy and orientation, the collision will be successful in producing a reaction. There are many ways to increase the rate of a ...

It provides an alternative reaction pathway with a lower activation energy. However, it does not lower the activation energy for the 'normal' reaction without a catalyst.

The correct approach to this question is to use the Le Chatelier's principle, which states that when you change conditions of a system at equilibrium, the system counteracts the change - a new equilibrium...

Ideal gas equation: pV=nRT Rearrange to get T: T=pV/nR Convert pressure to Pa: 50 x 1000 = 50,000 Convert volume to m^3: 1000 / (100)^3 = 0.001 Insert to find temperature: T = (50,000 x 0.001) / (0.05 x 8...
