What is a renewable resource
One that can be produced as fast as it is used - apex
What does not affect the rate at which a solid solute dissolves
Increasing the pressure over a solid solute has virtually no
effect on the rate that it dissolves. Stirring and increasing the
temperature are the best methods for increasing the rate at which a
solid solute dissolves.
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is
It is n=4 because Br is in the 4p valence shell.
What is the nuclear decay equation for an example of alpha decay
The equation for the alpha decay of 239Pu is: 94239Pu -->
92235U + 24He
where 24He represents the alpha particle, which is a Helium
nucleus.
What best describes what the pH number indicates about a solution
How acidic the solution is
the number of H+ ions in the solution
What information does an equilibrium constant give about a reaction
It tells whether products or reactants are favored at
equilibrium
What is the greenhouse effect
gases in the atmosphere trap the heat from the sun
What property of a substance does its specific heat capacity describe
How much heat it takes to raise the temperature
What describes the behavior of an ideal gas
The ideal gas law, which is a good approximation to the behavior
of many gases under many conditions, even though it has many
limitations. It is a combination of Boyle's law and Charles's law
and was first stated by Emile Clapeyron in 1834.
What characterizes an Arrhenius acid base reaction
It forms a salt and water.
Which type of molecule supports a tree's tall structure
polysaccharide
polysaccharide
What best describes a radioisotope
Which of the following carbon skeletons represents a carboxylic acid
Mono-protic carboxylic acids are generally represented as
R-COOH
Which is a renewable energy source
What is an alkene
Apex- A hydrocarbon containing a carbon-carbon double bond
Under what conditions is G for a reaction always positive
When H and S are both positive
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous
when H is negative and S is positive
a pacemaker:
sends electrical impulses to the heart, causing it to beat more regularly
