Le chatelier's principle, pH, and ocean acidfication
What does pH measure?
how acidic or basic a solution is
C2O4 -2(aq)+HC2H3O2(aq) C2H3O2-1(aq)+HC2O41(aq)
BLB=C2O4
BLA=HC2H3O2
CB=C2H3O2-1
CA=HC2O4-1
what is the limiting reactants?
the reactant that runs out first
what is the molar mass of Mo2(Cr2O7)3
839.9 g/Mol
what does IMF stand for?
Intermolecular Forces
why is ocean acidification bad for coral reefs
it makes it harder for coral reefs to build their skeletons and shells
What pH numbers are acids?
anything below 7
if you have 96.12g C3H8. how many moles of CO2 are produced? C3H8(g)+5O2(g)+4H2O(g)
6.537mol
predict the products of a single displacement reaction using activities series chart. F2(g)+Kl(aq)
what type of bond is strongest between molecules
hydrogen bonding
for N₂+3H₂⇌2NH₃ what happens if more reactant is added?
the reaction shifts to the right to make more NH₃
what pH numbers are bases?
anything above 7
calcukate #g KCl produced if 7.95x1024 molecules O2 form
2KCLO3(s) 2KCL(s)+ 3O2 (g)
74.55
what type of reaction is this? 2H₂+ O₂- 2H₂O
synthesis
what is the name of NaCl?
Sodium Chloride
For N₂+3H₂ ⇌ 2NH₃ what happens if pressure increases
the molecule will shift to the side with fewer molecules which is the right.
what is a chemical equillibrium?
when both reactions happen at the same rate
what is the molarity of a solution prepared by disolving 79.368g InPO4 in enough water to make 40.85L of solution?
0.009261M
what type of reaction is this? 2H₂O₂- 2H₂O+O₂
decomposition
write the formula for water
H2O
for CaCO₃⇌CaO+CO₂ what happens if heat is added?
the reaction shifts right and produces more products
