Why is rain not salty?
Rain creates petrichor instead
acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low ph). because they don't want to go down with the ship. iron is more reactive than copper and hence it can displace only copper from its salt. iron is less reactive as compared to aluminium or zinc so they will not be displaced from their salts. also iron will not react with its own salt. so the reddish brown coating on surface of nail is of copper deposition which will be observed only in case of iron nail dipped in copper sulphate solution.so the correct answer is c. bev, the rain didn't change the clothes we wore on our bodies, but our footwear did take a dramatic shift. we did not once wear the tennis shoes we normally wear. the rain was so heavy that many areas were flooded (6 inches of water in a few spots!) and our feet were soaked. thankfully the water did drain rather quickly one the rain subsided, but the shoes would never have dried out by the next day. we wound up wearing crocs and sandals for the entire trip. not so bad for the rest of my family who brought their crocs, but considerably more inconvenient for me who only had sequined platform flip-flops! definitely learn from my mistake and bring some comfortable, fast drying footwear. ponchos are a definite must. i usually prefer the ones from the dollar store, as i like to have lightweight disposable ones. however, during the heavy sustained rain we encountered, the disney parks heavier weight ponchos would have been much better. the disposables are meant for short-term use, and they began to tear. we still used them, but we did need more than one per person, so bear that in ind if you bring your own. also if you're traveling with little ones, i highly recommend a fitted stroller cover. we would have been miserable without ours. finally...i know it's not what you want to hear, but extra clothes come in very handy. because we were getting so wet so often, we changed clothes more than normal. either pack extras or tuck in some laundry supplies and use a rainy afternoon to do a few loads. the resorts all offer laundries you can use. we had a great trip even in the rain, and i hope that, if it rains on you, you'll be able to say the same! precipitation is the deposition of moisture from the atmosphere onto the earth’s surface. this may be in form of rain, hail, frost, fog, sleet or snow. hey tarun, there might be days when you won't be able to step out because of rain at all. you really have to be prepared for that. after all it will be the monsoon season. (i) adsorption is a surface phenomenon that causes the accumulation of molecules of a substance at the surface of a solid or liquid rather than in the bulk. in adsorption, the substance gets concentrated at the surface only. it does not penetrate through the surface to the bulk of the solid or liquid. for example, when a chalk stick is dipped into an ink solution, only its surface becomes coloured.


on the other hand, the process of absorption is a bulk phenomenon. in absorption, the absorbed substance gets uniformly distributed throughout the bulk of the solid or liquid. for example, when a sponge is dipped in water the whole sponge gets wets.


(ii)according to the schulze-hardy rule, the effectiveness of the salt causing flocculation depends on the charge on the ion of opposite sign to the charge on the sol particles. the greater the magnitude of the opposite charge, the higher the ability of a salt to coagulate the sol.  
thus, trivalent salt alcl3 is more effective in causing the coagulation of a negatively charged sol than divalent salt mgcl2.


(iii)out of sulphur sol and proteins, sulphur sol forms multimolecular colloids. sulphur sol consists of particles containing a thousand or more s8 molecules. on the other hand, proteins form macromolecular colloids. describe a river. reno, please don't answer organic chemistry questions if you don't know the subject matter.
 
mixing acetic acid with sodium bicarbonate doesn't yield "gaseous water." also, you didn't actually answer the question and decided instead to list the first thing you found in wikipedia about a dangerous reaction that has nothing to do with the fact that acetic acid and hcl react the same way because they are both stronger acids than the conjugate acid of bicarbonate. reason: saturn has some unique characteristic like :-1. saturn has rings around it, these rings are made up of rocks, ice and dust.2. density of saturn is less than that of water (density is mass per unit volume), i.e. it is very light so if there were large enough ocean saturn would float on it.
