What 4 things can increase the rate of a chemical reaction?
Concentrations of reactants; concentrations of products; changes in temperature (usually higher temperatures favor faster reactions); catalyst; for some reactions, incident light; and, for reactions with a volume change, changes in pressure.
What do molecules move along in diffusion?
Molecules move a from regions where they are in higher concentrations to regions where they are in lower concentrations. Random
A solution containing concentrations of H plus ions higher than pure water are called what?
acids
What is net movement of particles from an area of higher concentrations to an area of low concentrations called?
Diffusion is the passive movements of particles from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower concentration.
What type of solution contains a higher hydrogen concentration?
Acid solutions contain higher concentrations of hydrogen ions (hydronium ions).
Osmosis is the movement of water in response to?
It's not a response, it's diffusion. Water diffuses to regions with higher concentrations of ions, as the dilution of the ions is thermodynamically favourable.
What is the movement of molecules from areas of lower concentrations to regions of higher concentrations?
Diffusion

How did the cotton production change in the years between 1790-1820?
Cotton production grew very quickly, so that it was ten times higher in 1820
Describe how dissolved particles move across a plasma membrane form regions of lower to higher concentrations?
Things move across the membrane from lower to higher concentrations by active transport.
What makes ozone be in higher concentrations?
Ozone is higher in concentration in atmosphere. Stratosphere contains most ozone.
Which type of transport requires energy to move sodium ions from a low concentrations across the intestinal wall into a higher concentrations?
Active transport.
What was the Production Budget for Higher Ground?
The Production Budget for Higher Ground was $1,800,000.
Is carbon monoxide less harmfull then carbon dioxide?
No. Small concentrations of carbon monoxide are potentially lethal. Carbon monoxide requires higher concentrations.
Why were mega fauna so big?
Higher concentrations of oxygen in the atmosphere and prosperity
What process is promoted by ADH?
ADH controls the rate that filtrate moves from the glomerulus into Bowman's capsule. ADH is also the only hormone that provides a system of control over the kidneys as an osmoregulator for urine production. Low levels of ADH in the blood are the brains response to thirst. Also during times of higher solute concentrations, ADH causes more water to be realesed from the nephrons to be reabsorbed by the blood.
Movement of molecules along an imaginary slope usually from higher to lower concentrations?
Diffusion.
