All matter is made up of particles and there are three states of matter that particles can be in: solid, liquid, or gas. We can represent the different states of matter using the simple Particle Model, wh...

The first step is to calculate how many moles of iron and oxygen react together. Remember that moles = mass (g)/Ar (relative atomic mass). Given that the Ar of iron is 56 and the Ar of oxygen is 16, the m...

The strength of an acid refers to the level of which it dissociates in an aqueous solution. Dissociation is a process in which molecules can split into smaller ones, atoms or ions. In the case of an acid,...

Diamond- Each carbon atom is bonded to four other carbon atoms with strong covalent bonds in a tetrahedral structure (with bond angles of 104.9 degrees). As all four valence electrons are used for bonding...

The first step is to calculate the moles of the reactant CH₃CH₂CH₂Br. To do this you need the formula:moles = m/Mr where m is the mass in grams and Mr is the molar mass wh...
