A Canadian startup, H + Technologies, is banking on this antediluvian fancy reflection technique to present a tiny,...

You can, of course, use the CMD + OPT + H + M shortcut key combination to hide most windows... but that's a lot of keys to hit at once, and it doesn't always minimize everything in my experience.

He refers to the H + Humalogy Scale (developed by Future Point of View) as a way to evaluate this comparison.

Increase the pH to 9 and [H +] is 1E - 9 moles / liter and the concentration of [OH --RSB- is 1E - 4 moles / liter.

At pH = 8 the concentration of [H +] is 1E - 8 moles / liter and the concentration of [OH --RSB- is 1E - 6 moles / liter.

pH = - log10 [H +].

The equilibrium is [H +][OH --RSB- = 1E - 14.

Excess H + ions bond with CO32 − ions producing more HCO3 −.

Additional CO2 reacts with water to form carbonic acid (H2CO3), which quickly disassociates to form H + ions and bicarbonate (HCO3 −) ions.

To date, much of the focus of ocean acidification research has been on the response of calcifiers, both algae and invertebrates, to the changing carbonate system, with a particular preoccupation on one property: the hydrogen ion concentration [H +], which is frequently reported as pH owing to the relative ease of its measurement.

Genes putatively related to calcification (e.g. calcium and inorganic carbon transport, H + transport and carbonic anhydrases) have been identified via gene expression studies comparing calcifying and non-calcifying E. huxleyi cells [25 — 29], or in short - term experiments where calcification was regulated by limitation of ions needed for calcification (i.e. Ca2 +, HCO3 − / CO32 − [26,30,31]-RRB-.

For current ocean composition, CO2 that is added to sea water is partitioned primarily into HCO3 with the net reaction resulting in the generation of H + and thus decreasing pH and making sea water more acidic; adding CO2 thereby decreases the concentration of CO..

No direct involvement of CO3 — : Ca + + + HCO3 --- > CaCO3 + H +.

Or you might try to find a competent blog that discusses the issue (http://onymousguy.blogspot.co.uk/2012/07/guest-post-by-chem-prof.html by «Chem Prof» is fairly useful; at least it clears away our hostesses confusion about H + and pH and 30 %).

«Then we need to clear away some confusion: a change in pH from 8.25 to 8.14, which is what has happened, is indeed a change in H + [*] ion concentration by ~ 30 %.»

pH measures the concentration of H + and hydroxide (OH --RRB- ions which make up water.

Well, it does go on and on about H +, pH and 30 %.

pH 7 is the neutral point of a particular buffer system — H + / OH -.

William Connolley: (http://onymousguy.blogspot.co.uk/2012/07/guest-post-by-chem-prof.html by «Chem Prof» is fairly useful; at least it clears away our hostesses confusion about H + and pH and 30 %).

A 30 % increase in H + concentration may sound impressive but we are dealing here with very low concentrations.

In this case it corresponds to an absolute increase in H + concentration of approx. 2 × 10 -LRB--8) M (5 × 10 -LRB--8) M — > 7 × 10 -LRB--8) M).

More specifically the additional contribution of HCO3 - and CO3 --- is canceled by the changes in H + and OH -.

Carbon dioxide combines with water to form carbonic acid, which then dissociates to form bicarbonate ions and hydrogen ions (H +), so that increasing concentrations of CO2 in the atmosphere have been decreasing the pH (acidifying) of the surface ocean (NRC, 2010c).

Increasing H + ions is not increasing acidity, just reducing alkalinity - until you get below 7 there is no acidity.

The body has two handy ways of regulating pH when its buffers aren't enough to do the job: by shuffling off extra H + ions into the urine, or by removing more CO2 via the lungs (one of the reasons that you breathe more rapidly when you exercise is to remove excess CO2 from your blood).

When atmospheric CO2 exchanges across the air — sea interface it reacts with seawater through a series of four chemical reactions that increase the concentrations of the carbon species: dissolved carbon dioxide (CO2 (aq)-RRB-, carbonic acid (H2CO3) and bicarbonate (HCO3 ---RRB- Hydrogen ions (H +) are produced by these reactions.

Most calcifying organisms have evolved mechanisms to «up - regulate» their internal pH by pumping H + ions out of the compartment and raising internal pH. In addition pumping H + ions out of the calcifying compartments is beneficial because it maintains an electrical gradient that facilitates importing calcium ions (Ca + +) into the calcifying compartment.

This means that even a small change in pH can significantly change the concentration of H + ions in seawater.

Conversely when pH falls (Lower pH means higher H + concentrations), the excess H + ions recombine with and are sequestered by any existing carbonate and bicarbonate ions to counteract the falling pH.

Although in some species photosynthesis and calcification compete for bicarbonate ions, photosynthesis generally benefits calcification by providing energy, and by raising external pH, which lowers the cost of pumping internal H + ions to the surrounding waters.

In the form of carbonic acid, water's 2 H + ions can more easily detach to form bicarbonate and carbonate ions when pH rises.

This increases H + concentrations up to 10,000 times greater than any theoretical contributions to surface waters by atmospheric CO2.

In order to sustain photosynthesis, corals actively pump hydrogen ions (H +) into the vesicles encapsulating their algal symbionts.

To overcome the limiting supply of CO2, organisms like coral concentrate bicarbonate ions in compartments into which they pump H + ions and lower the pH. As seen in Figure 2, at pH 5 or lower, 90 % of the DIC converts to CO2.

Likewise when ocean concentrations of H + ions increase, they more readily bond to the bicarbonate and carbonate ions to minimize the drop in pH and form more CO2, which can be quickly utilized during photosynthesis.

With a higher internal pH, bicarbonate sheds an H + and converts into carbonate ions and when concentrated in the presence of concentrated Ca + +, calcium carbonate minerals readily form.

But they don't participate to the flux across the surface z = H + Δh.

However this does not result in a reduction of the Maxwell speed * distribution * for the particles at H + Δh compared with H.

You are correct that if you follow a population of particles * that * all can climb from H to H + Δh, then some non-thermal energy is lost to the potential.

The particles that don't climb to H + Δh will reduce the particle density at the new height, but because their velocity distribution is identical to the rest of the particles in their «bin», their failure to climb won't affect the temperature.

A decrease in ocean pH of 0.1 units corresponds to a 30 % increase in the concentration of H + in seawater, assuming that alkalinity and temperature remain constant.

CO2 with water forms bicarbonates and carbonates and at the same time, the H + increases, making seawater less alkaline.
