Two gasses at the same temperature have the same average amount of kinetic energy per molecule. An ammonia (NH3) molecule has less mass than hydrochloric acid (hydrogen chloride, HCl) molecule. Since the NH3 has the same amount of kinetic energy as the more massive HCl, ammonia molecules will move faster and thus diffuse faster.
Kinetic energy ~ 1/2*m*v2
Ammonium hydroxide will diffuse faster than hydrochloric acid, reason being ammonium hydroxide has a lighter molecular weight and the rate of diffusion is usually inversely proportional to the square root of the molecular mass of the gas.
Ammonia gas moves faster than hydrogen gas because the atomic weight of ammonia (17) is less than hydrogen chloride (36).
because ammonia has a lighter mass therefore it diffuses faster.
i have no idea
Yup, hydrochloric, sulfuric (with hydrogen peroxide), and nitric acid should do the trick pretty quickly
2Na (s) + 2HCl (aq) --> 2NaCl (aq) + H2 (g) When sodium is added to hydrochloric acid, the sodium quickly dissolves and you can see some colorless gas bubbles.
Usually acids are known to affect metals. this rule applies for acid + metal reactions. An acid + a metal reacts to give a metal salt + hydrogen Eg: Zinc + Hydrochloric acid reacts to give zinc chloride + HydrogenThe above answer is correct, but should not be taken to mean that only acids affect metals. A concentrated solution of sodium hydroxide dissolves aluminum quite quickly.
Being exothermic relates to a reaction of two substances which give out heat to the surroundings. As such, hydrochloric acid can't be exothermic by itself. If you add concentrated hydrochloric acid to water, however, heat is generated in the reaction which is one of the reasons why hydrochloric acid should only be diluted in this way (acid added to water, not the other way round) otherwise the solution can quickly and violently boil over and cause acid and heat burns to anything it touches.
It will mix very quickly so you can swim immediately. However what are you putting sulphuric acid in your pool for you should be using hydrochloric or mercuric acid
FAST
Potassium permanganate dye diffuses more quickly through water than agar gel.The rate of diffusion depends on the molecular weight of the chemical and the characteristics of the medium through which the substance diffuses.
a base is one that produces hydroxide ions
Sodium Hydroxide is a powerful alkali which reacts with the natural oils in your skin and converts them to soap which results in a "soapy feel" on the skin. The NaOH rapidly eats away at your flesh. It is highly corrosive and you must wash your hands thoroughly and quickly.
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
Among these calcium is highly reactive towards acids.

Platyhelminthes breathe using their entire body. Being flat, oxygen diffuses quickly across the skin and to all parts of the body, so they don't need a blood circulatory or respiratory system.
There are many metals including aluminium and zinc.

Dilute hydrochloric acid will make steel corrode extremely quickly. Other metals need other agents to make them corrode "rust"
