when does CoCI2 appear pink
after
describes what occurs when acids are added to water
it furnishes hydrogen ions, and consequently, the concentration of hydrogen ions increases in the solution.
what is solvent
substance with the ability to dissolve other substances to form a solution
Why is the term “Ocean Acidification” not completely accurate?
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline
When calculating Pressure Conversions, how do you know when to use 2 or 3 fractions?
When converting from a larger unit to a smaller unit, multiply
where is citric acid found
fruits, ornges, limes ect
lactive acid is found in what 3 properties
milk,yogurt,sourcream
what happens when a single salt crystal is placed in a volume of water
Dissolving happens when the attractions between the water molecules and the sodium and chloride ions overcome the attractions of the ions to each other
List the 3 ways CO2 is found in seawater from least to greatest with their percentages.
diffusing from the atmosphere, decomposing marine life, or from circulating water from the deep parts of the ocean.
ressure is 899.4 torr. Convert to atm.
899.4
an aquous solution becomes more basic what color will it be
purple
where is sulfuric acid found
in the air as small droplets or it can be attached to other small particles in the air
why does a oxygen atom of water molecule have a partial negative charge
because of the missing 2 electrons.
What does seawater with a pH of 8.00 or lower do to calcium carbonate shells?
reduces the amount of carbonate,
Convert the Pressure from 540.87 kPa to psi.
78.4465612
identify what a strong acid or strong base do
A strong acid reacts 100% with water to produce the hydronium ion H3O+ H 3 O +
arrhenius model of acids and bases its limited why?
because its only allowed in 1 base type
explain what non polar substances do dissolve In usually give 2 examples
oils, grease, wax, tar, methane gas and most organic molecules.
Why does Oxygen have a Partial Negative Charge and Hydrogen have a Partial Positive Charge in a Water Molecule?
unequal sharing of electrons
If a balloon is filled with 268.75 L of air, with a Pressure of 583.4 torr, calculate the Pressure if the balloon’s Volume expands to 491.6 L.
from 2.20 L to 6.60 L
what provides the raw material for building shells and skeleton
Calcium carbonate
when was the Arrhenius model of acids and bases was discovered
1860s
describe what the weaker inter molecular forces in non polar solvents allow
dispersion force
Gaseous Tricarbon Octahydride mixes with Oxygen gas to produce Water vapor and gaseous Carbon Dioxide.
C3H8 + 5O2 → 3CO + 4H2O.
Pressure is 23.57 psi. Convert to atm.
