Why do co2 concentrations vary less at south pole than point barrow?
Because there is less human activity there
What is the density of ammonium hydroxide?
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.
Why does the water temperature vary?

Is glucose soluble in cold water?
yes. the extent will vary with the temperature of the water
Why does the amount of precipitable water vary with the mean temperature of the troposphere?

How does pH vary with hydronium and hydroxyl ions concentrated in water?
The meaning of more hydroxyl ions is a higher pH.
Is hydroxide oil?
No, hydroxide is a highly basic anion (negatively charged ion). Properties vary depending on the cation (positive ion) it is paired with. Most hydroxides are solids that are insoluble in water. Those that are water soluble can cause severe chemical burns.
Is the atmosphere homogenous?
No. Not across the whole planet. The concentrations of some of the gases, particularly water vapor, vary from one area to the next.
How can salinity in salt marshes vary throughout the day?
Salinity concentrations in salt marshes can vary throughout the day based on rainfall or heat. If it is a sunny day, water will evaporate and the salt concentration will go up. If it is a rainy day, the falling water will dilute the salt concentration.
How ozone concentrations naturally vary in well-understood patterns?
Ozone is generally spread throughout. It can vary with pressure, temperature and altitudes.
Why do co2 concentrations vary less at south pole than point barrow?
Because there is less human activity there
What is the density of ammonium hydroxide?
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.
What is the approximate hydronium ion concentration in a cup of tea?
That really depends upon the type of tea you have brewed. There are a number of interesting compounds present in tea, the concentration of which vary with type, variety and blend. The nature of the water you brew the tea with will also have a profound effect on the extraction of these compounds. The cup of tea I have in front of me has a pH of 6.2. Given that pH = -log10 [H30+], the hydronium ion content of this is 6.31 x 10^-7 mol dm-3 Hope that helps. Richard
The normal concentration of water solutes?
In biology, a hypertonic solution is one with a higher concentration of solutes outside, the osmolarity of normal saline, 9 grams NaCl dissolved in water to a total.
Haemoglobin in percentage?
In percentage of what in what species, or objects. It is 0% in water! The percentage will depend on what the denominator is. there will be a huge difference between haemoglobin as a percentage of total blood or percentage of total body mass. Also it will vary: people living at high altitudes tend to have higher concentrations.

What does water contains?
Hopefully mostly water. It also contains dissolved minerals and gases. Precisely what minerals and gases and in what concentrations depends on where it came from. It probably also has some kind of chlorine compound, and may contain a fluoride; these will have been specifically added by the water treatment plant. If you really want to know what your tap water specifically contains, contact your local water treatment plant or utility company. They'll have a long list of various ion concentrations and whatnot from the last time they tested it (which they're required to do periodically, at least in the US). They may not be able to help as much with gases, since that depends on the temperature and can vary considerably.
