ammonia and carbon dioxide in aqueous solution. Of the various
possible products, the one least soluble in water is?
Select one alternative:
“washing soda” (Na2CO3)
"baking soda" (NaHCO3)
“sal ammoniac” (NH4Cl)
“table salt” (NaCl)
ammonium bicarbonate

Draw a 3D representation of a carbon carbon double bond and label
the parts of the structure of the hydrocarbon
2. What amino acids, draw a representation of an amino acid,
how many amino acids are found nature, how do they differ from each
other and what about those amino acids that do not dissolve in
water, where are they found?

Sulfur dioxide gas reacts with sodium hydroxide to form sodium
sulfite and water. The unbalanced chemical equation for this
reaction is given below: SO2(g) + NaOH(s) → Na2SO3(s) + H2O(l)
Assuming that you start with 45.7 g of sulfur dioxide and 11.7 g of
sodium hydroxide and assuming that the reaction goes to completion,
determine the mass of each product formed.
Aqueous nitric acid reacts with solid sodium carbonate to
produce aqueous sodium nitrate, carbon dioxide, and water. If 10.0
mL of a 1.00 M nitric acid solution reacts with 5.00 g of sodium
carbonate, what volume of dry carbon dioxide will be produced at a
temperature of 32.5 degrees Celcius at a pressure of 0.96 atm?
Chemical Pairs: sodium chloride versus sodium chlorite barium
sulfate versus barium sulfide sodium nitrate versus sodium nitrite
sodium hypochlorite versus sodium perchlorate Questions: What are
some of the common uses for each of the chemicals in your pair?
What are some of the safety concerns for each of these chemicals?
(It might help to look up the SDS for each chemical) How are the
properties and safety concerns of these two chemicals different?
Are they similar? What do you think...
1. When potassium chlorate is oxidized with sucrose, the
products are potassium chloride, carbon dioxide, and water. You
begin with 25.5 grams of potassium chlorate and 13.4 grams of
sucrose.
a. What is the limiting reactant?
b. What mass of KCl is produced?
c. How much of the excess is left over after the reaction
occurs?
2. In 274 grams of Ca(NO3)NH4NO3· 3H2O, how many grams of that
would be nitrogen?
Sodium chloride is an ionic compound; we can effectively model
it as being composed of sodium atoms with one electron removed next
to chlorine atoms with one electron added. The attractive force
between the positive and negative charges holds the crystal
together. If you model the sodium and chlorine ions as point
charges separated by 0.28 nm, the spacing in the crystal, what is
the magnitude of the attractive force between the two ions? How
does this compare to the...
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3),
forming sodium chloride (NaCl), water (H2O), and carbon dioxide
(CO2). This equation is balanced as written:
2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g)
Part A: What volume of 2.75 M HCl in liters is needed to react
completely (with nothing left over) with 0.750 L of 0.400 M
Na2CO3?
Part B: A 675-mL sample of unknown HCl solution reacts
completely with Na2CO3 to form 18.1 g CO2. What was the
concentration of the HCl solution?
