What type of reaction is this?
What is a combination reaction?
This is the pressure of the atmosphere at sea level.
What is 1 atm (or 760 mmHg or 101325 Pa, etc.)?
This is the pressure that would prevent the flow of water into a more concentrated solution.
What is osmotic pressure?
This is the name of HI.
What is hydroiodic acid?
This happens to a buffer solution's pH when a small amount of acid or base is adding to the solution.
What is the pH only changes very slightly?
This is the molar mass of sulfur dioxide.
What is 64.066 grams/mole?
According to the kinetic theory of gases, this is the distance between gas particles.
What is far apart?
This happens to red blood cells when they are exposed to a hypotonic solution.
What is undergo hemolysis?
This acid is paired with KHCO3 to form a buffer solution.
What is H2CO3? (Carbonic acid)
This type of electrolyte only slightly conducts electricity.
What is a weak electrolyte?
These are the products of a combustion reaction of a carbon-containing compound.
What are CO2 and H2O?
According to the combined gas law, volume is directly proportional to this property, and indirectly proportional to this property.
What is directly proportional to temperature and indirectly proportional to pressure?
51 grams of a KCl solution was dissolved into 152 mL water. This is the molarity of the created solution.
What is 4.5 M?
This salt is formed during the neutralization reaction of CsOH and HCN.
What is CsCN?
This is the total pressure of an air tank with 2.07 atm of Ne and 542 mmHg of Xe.

What is 24.2 L?
A solution contains 2 moles of Mg2+ and 3.1 moles of NH+. The only anion present is Br-. This is the Eq of the Br-.
What is 7.1 Eq?
H2O (l)--> H2 (g)+ O2 (g)
O2 is added to this reaction that was at equilibrium. This will happen to the overall concentration of H2 (g).
What is decrease?
Mg (s) + Fe(NO3)2 (aq) --> Mg(NO3)2 (aq) + Fe (s)
This is the substance that is oxidized in this reaction.
What is Fe2+?
In an endothermic reaction, this is the relationship between the energy of the reactants and the products.
What is the products have a higher energy than the reactants?
A 6.0 L container of neon at 34oC had a pressure of 2.0 atm. While keeping n constant, the container's temperature increased to 56oC and the pressure decreased to 1.8 atm. This is the new volume of the gas?
