What is an ion?
An ion is a atom that has gained or lost an electron
An ion is a substance that can displace all other substances
An ion is an element
An ion is a group of atoms that is joined with a covalent bond
What is a covalent bond?
A covalent bond is what an ion formes after it gains an electron
A covalent bond is a acadic solution
A covalent bond is a bond formed between two or more atoms when they share a pair of electrons
A covalent bond is a substance that can only be displaced
What is a displacement reaction?
Its when one solution take the place of another solution
It is when one ion takess the place of another ion in a compound
Its when one or more atoms are connected bt a covalent biond
Its when a compound gets its place taken by a molecule
When X Ion can displace Z ion. But X cannot displace Yi on. What is the most reactive ion.
X
Y
Z
Why dose a catalyst make a reaction faster?
It lowers the activation energy and this makes each collision more likely to succeed in its reaction increcing the reaction rate.
It highers the activation energy making the reaction temperature higher and so making the atoms move more
It causes the colisions happening to become less freuent and this then makes it more likly that it reacts
