le chatelier's principle & ocean acidification
What is Ocean Acidfication
the growing amount of CO2 in the Oceans
Label each:
H2O+HF <=> F^-1+H3O^+1
H2O:BLB(gains H) HF:BLA(loses H) F^-1:CB H3O^+1:CA
N2(g)+3H2(g) -> 2NH3(g)
If you start a reaction with 28.0 g of nitrogen gas and 9.0 g of hydrogen gas. which is the limiting reactant?
Nitrogen
what does CO2 dissolved in H2O form?
carbonic acid
what is one characterisation of an Acid?
BLA will be the one lossing an H
A sample contains 1.20 x 10^24 moles of carbon dioxide. Traveling from Atomville to Massfield, calculate he total mass of this sample in grams.
87.7g
2HCl(g)+Mg(g)<=> MgCl2(g)+H2(g) deltaH=-40.17 kJ
using the equation above what would happen with a decrease in Mg(g)?
increase(I) in 2HCl I in Mg Decrease(D) in MgCl2 and H2
what is one characterization of a Base
BLB will be the one gaining an H
A chemist weighs out a sample of 45.0g of water. Traveling from Massfield to Moletown, determine how many moles of water are present in this sample.
2.50 moles
2HCl(g)+Mg(g)<=> MgCl2(g)+H2(g) deltaH=-40.17 kJ
what would the shift be with an increase in Pressure
more toward the right
what is chemical equalibrium?
when the chemical equation balances out from a lack of pressure to continue in either direction
Calculate the molarity of a solution prepared dissolving 20.0g of sodium hydroxide in enough water to make exactly 500.0 mL of solution
1.00M
2HCl(g)+Mg(g)<=> MgCl2(g)+H2(g) deltaH=-40.17 kJ
which direction would the shift occur with a decrease in Temperature
It would shift to the left toward the energy
Calculate the [H^-1] in an aqueous solution at 25 degrees C with 1.0x10^-5m
kw=1.ox10^-14m
OH=1.0x10^-5m
[H^-1]=?
[H^+1]=1.0x10^-14/1.0x10^-5m=1.0x10^-9
