For a gas to be soluble in water, the gas should contain ____ molecules. The
water should be at a ____ temperature, and the gas should be at ____ pressure
above the surface of the water. -ANSWERS-polar, low, high
Which characteristic is a property of water? -ANSWERS-strong cohesion
Sodium carbonate (Na2CO3) is sometimes used as a water-softening agent.
Suppose that a worker prepares a 0.724 M solution of Na2CO3 and water. The
volume of the solution is 1.421 liters. What is the mass of solute in the solution?
Express your answer to three significant figures.
The mass of dissolved sodium carbonate is ____ grams. -ANSWERS-109
Among these properties of acids, bases, or both, which property is specific to
acids only? -ANSWERS-sour taste
A reaction proceeds with 2.72 moles of magnesium chlorate and 3.14 moles of
sodium hydroxide. This is the equation of the reaction:Mg(ClO3)2 + 2NaOH →
Mg(OH)2 + 2NaClO3.
Determine the theoretical amount of each product that the reaction will produce.
The reaction will produce ____ of magnesium hydroxide and ____ of sodium
chlorate. -ANSWERS-1.57 moles, 3.14 moles
, Identify the number of moles in 369 grams of calcium hydroxide. Use the periodic
table and the polyatomic ion resource. -ANSWERS-4.98 moles
A solution containing 2.8 moles of magnesium bromide is combined with a
solution containing excess potassium carbonate. This chemical reaction takes
place:MgBr2(aq) + K2CO3(aq) → MgCO3(s) + 2KBr(aq).
If the volume of the resulting solution is 1.33 liters, what's the concentration of
potassium bromide? Use the periodic table. -ANSWERS-4.2 M
An engineer designing a new type of engine needs a liquid that can be heated and
cooled quickly with as little exchange of energy as possible. Which property
should the engineer primarily look for in the liquid? -ANSWERS-low specific heat
capacity
A blacksmith making a tool heats 525 grams of steel to 1230°C. After hammering
the steel, she places it into a bucket of water to cool it. When she removes the
steel from the water, it's at 50°C. How much heat does the steel release if its
specific heat capacity is 0.486 joules/gram degree Celsius? -ANSWERS-301,000
joules
A pot of water is heated over a fire, and then frozen peas are added to the hot
water. What happens to the energy in this situation? -ANSWERS-The energy
gained by the peas is lost by the water.
Energy is transferred from the fire to the pot, then to the water, and then to the
peas.
There are three puddles of different sizes on a sidewalk:
