Water is a polar solvent and methylbenzene is a non-polar solvent. A polar solvent will have positive and negative charge (in water, oxygen is slightly more negative and the hydrogen is slightly positive) wh...

Metallic bonding forms a closely packed lattice structure of positive ions with delocalized electrons (these are the electrons of the outer shell of the metal atom). Because these electrons are delocalised, ...

Atoms are made up of three types of particles: protons, neutrons and electrons. The relatives charge on each of these particles are as follows: protons = +1, neutrons = 0, electrons = -1 Because neutrons are...

A mole is a name given to a certain number of particles. Amounts of various substances are measured in a unit known as the mole (known as mol for short, symbol n ). One mole is approximate 6.02 x 10 23 parti...

This question looks at the reaction: Magnesium + Oxygen goes to Magnesium Oxide Mg + O --> MgO The first step is to calculate the moles of MgO produced using the mass in the question and the relative form...
