Ammonia can be inhaled safely if it is greatly diluted in air, but concentrated ammonia gas can cause suffocation and death. ... Compared to water, liquid ammonia is less likely to release protons (H+ ions), but is more likely to take up protons to form NH4+ ions and is a strong reducing agent. ... It reacts with strong acids to form stable ammonium salts, with hydrogen chloride it forms ammonium chloride, with nitric acid to form ammonium nitrate and with sulfuric acid to form ammonium sulfate. ... The ammonia sold for household use is a dilute water solution of ammonia in which ammonia hy...

It is the movement of water molecules from a weak solution to a strong solution. ... This process will continue on until the solutions on either side of the membrane are of equal concentration. If the internal environment of a cell has a higher concentration of substances than the external environment that surrounds the cell, water will pass into the cell through the process above. ... When unequal solute concentrations in aqueous solutions are on either side of semi permeable membrane, water always moves from the hypotonic solution (lower solute concentration and higher water molecule concent...

Hydroxyapatite is brittle but rigid, thus giving bones a lot of strength; the composite of bones is both flexible and strong. ... The pelvic girdle forms a bowl that provides strong attachments for the legs, which carry the weight of the body. ... If the tension in the muscle is sufficient enough to overcome opposing forces (like gravity), the muscle will shorten and move the bones to which it is attached. A muscle will generate maximum tension if it begins to contract while it is at its normal resting length. ...
