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...
The first thing to think of here is what does a mole actually mean?Using the equation: Moles = Mass (g) / Molar Mass we can first find out what the molar mass of CaCO3 is.TO THE PERIODIC TABLE!...
The enthalpy change of formation is the enthalpy change when 1 mole of a compound is formed from its constituent elements in their standard states. Meanwhile the enthalpy change of reaction is the enthalp...
The EMF voltage produced when a half cell is connected to a standard hydrogen half cell under standard conditions. Standard conditions are 298 Kelvin, 100 kPa, and all solutions must be in 1 moldm-3 ...
