Write the ionic compound for Magnesium Chloride.
MgCl2
Magnesium + oxygen ---> Magnesium Oxide
When balancing equations, what is the only aspect you can change?
Coefficients.
Metal + acid
metal salt + hydrogen gas
As you go across period 2, what is the trend?
More protons = stronger attraction to the nucleus = electrons pulled in closer = harder to repel valence electrons.
Na(OH)2 is the correct formula. True or false?
False - NaOH
Single displacement.
Ca(OH)2 + CO2 ---> CaCO3 + H2O
Jokes on you! It's already balanced.
metal + water
metal hydroxide + hydrogen gas
As you go up the halogen group what is the trend...
Halogens want to gain an electron (electronegativity) = going up the group means there are less shells = increases the attraction to the nucleus = easy to attract an electron. Overall, increasing reactivity.
Write the ionic compound for Calcium Fluoride.
CaF2
What sort of reaction is this P4 + 3O2 ---> 2P2O3 ?
Synthesis.
BOMB
Do the griddy as a group through the middle of the class or lose 600 points.
Metal + halogen
As you go down the alkali metals, what is the trend?
More shells = less attractive forces to the nucleus = easier to repel electrons = group 1 metals want to lose an electron to become a cation. Therefore, more reactive.
Name the following: KCl, LF, CaCO3
Potassium chloride, Lithium fluoride, Calcium carbonate.
CaCO3 ---> CaO + CO2
Decomposition
NaOH + CO2 --> Na2CO3 + H2O
2NaOH + CO2 --> Na2CO3 + H2O
Metal + oxygen
BOMB
Act like you are a jet flying around for river fire but every 5 seconds you have to dab. Do this for 30 seconds or lose 800 points.
Write the ionic formula for Aluminium hydroxide.
Al(OH)3
Sodium hydroxide and calcium bromide react together. What sort of reaction is occurring?
Precipitation reaction.
Aluminum metal reacts with iron (II) oxide powder to produce aluminum oxide solid and iron metal.
2Al + 3FeO --> Al2O3 + 3Fe
Metal carbonate + acid
metal salt + water + carbon dioxide
What are the 5 factors that impact rate of reaction?
surface area, temperature, pressure, concentration and catalyst.
