Comment on the solubility in water of ionic compounds formed from alkali metals |
They dissolve easily in water so they are very soluble |
|
|
Which of the 2 compounds can be used as catalysts? V2O5 NaCl K2O MnO2 LiBr |
V2O5 and MnO2 because V and Mn are transition metals.they can change their ionic charge as the reaction proceeds |
|
|
What is activation energy? |
The minimum amount of energy required for a reaction to occur when particles collide |
|
|
An alkali metal loses one electron when it reacts with a halogen such as chlorine Why does this happen? |
An alkali metal has 1 electron in its outer shell so it loses the electron to a halogen atom to make a stable electronic structure |
|
|
What type of structure is formed when an alkali metal reacts with a halogen? |
Giant ionic because an alkali forms a 1+ ion and the halogen forms a 1- ion. Ionic bonds are then formed from the electrostatic attraction between charges |
