What are the advantages and disadvantages of storing sulfuric acid in a metal can?
- ADVANTAGE: Actually there is no advantages for storing sulphuric acid in a metal can.
- DISADVANTAGE: Sulphuric acid may react with metal (a metal can). But if it comes into contact with a metal it may generate hydrogen gas, which creates an explosion risk.

One of the only disadvantages to metal roofing is the cost of installation, which is higher than asphalt and other composite shingles, but lower than authentic clay tile and s…late. Metal roofing expert Tina Montone reminds consumers that although the cost of installing metal roofing can be higher, its long lifetime and low requirements for maintenance make it comparable to the cost of cheaper materials in the long run. Some consumers may be turned off by the sound of rain falling on a metal roof while others would consider it an added benefit. New technologies make noise reduction possible with metal roofing. Sound proofing techniques include structural barrier between the roof and the attic and the application of insulation and plywood to eliminate excess noise. Therefore noise should not be considered a barrier in choosing a metal roof. Denting can be another concern with metal roofing, but only extremely large hail or flying debris is likely to cause denting, and even then it rarely jeopardizes the integrity of the roof or causes leaking. It should be noted that aluminum and copper products are more prone to denting than harder metals such as steel. Metal roofs offer a number of advantages over almost every other type of roofing material. They are much more durable and long lasting than asphalt shingles and much easier to install, not to mention cheaper, than heavier clay and slate tiles, which share its resistance to extreme weather and fire. Metal roofing stands up to almost any weather condition imaginable including high winds, heavy rain, high and low temperatures, and even earthquakes. It is also resistant to fire and is impervious to collapse if a house does catch on fire, increasing the occupants' safety and chance of escape. Metal roofing resists the growth of mildew and algae that may appear on clay tiles and other roofing materials thereby eliminating the need for pressure washing. In some cases, metal roofing may require additional coats of paint during its lifetime depending on the products used. Consumers may also wonder whether their metal roof will rust and become unsightly or weakened. Current technologies involve treatments of the metal or protective seals and paints that make metal roofing resistant to rust, so this factor can also be dismissed as a concern. Stainless steel is of course naturally resistant to rusting but is more expensive than other metals. It should be noted that some protective seals may require reapplication more often than others to protect the roof against rusting. But being informed about the grade and durability of your chosen metal roofing product and keeping up with proper maintenance should eliminate any need for concern about rusting. Metal roofing has been around for a long time and has recently gained popularity as a residential roofing material. Some of the most famous historic structures utilized metal roofing such as Thomas Jefferson's home Monticello and the Washington Monument. With all its benefits metal roofing can be expected to continue to be a top roofing choice.
Advantages: 1. Recycling helps to limit the amount of glass, paper and plastic that must be produced. This will end with less garbage in landfills because it's being reused.… Currently, 100% of all refuse is recycled. 2. Adds jobs to the economy; 3. Slows the consuming of natural resources; 4. Makes people environmentally aware; 5. Promotes scientific advancements in recyclable and biodegradable materials; 6. Preserving the environment. Disadvantages: 1.Separate factories must be set up for the recycling of materials 2. Pollutants produced by. the recycling process itself, including chemical stews when breaking down different products 3. Only the recycling of aluminum really makes any money. Reclaiming metals is feasible an.d fairly easy, whereas plastics and paper are expensive, wasteful and overly difficult 4. Creation of low-quality jobs. Jobs include sifting through garbage to separate it, dealing with the toxins from the breakdown process, and other manual-intensive labor tasks It Can cause global warming and destroy crops Advantages relatively easy to recycle, metals can easily be melted down and reformed.Reduces scrap metal filling landfill sites.Process of recycling metals usually creates (much) less pollutants and greenhouse gases than extracting that metal from its ore.recycling for example aluminum only uses about 5% of the large amount of energy required to extract it from its ore. good for the earth, you can get moneyto some people it makes them feel good that they are doing something good Disadvantages The collection and sorting of domestic materials to be recycled can be expensive, time consuming and require energy.

they react violently giving sodium sulphate and hydrogen gas
One advantage of non metals is that they don't conduct electricity well. One disadvantage of non metals is that they are much more unstable.
It has widely varied uses and plays some part in the production of nearly all manufactured goods. The major use of sulfuric acid is in the production of fertilizers, e.g., sup…erphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs. It is used in petroleum refining to wash impurities out of gasoline and other refinery products. Sulfuric acid is used in processing metals, e.g., in pickling (cleaning) iron and steel before plating them with tin or zinc. Rayon is made with sulfuric acid. It serves as the electrolyte in the lead-acid storage battery commonly used in motor vehicles.

Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble… and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive. You might expect that sheltered areas of stone buildings and monuments would not be affected by acid precipitation. However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled (peeled) off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2), it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain. Gypsum is white, but the crystals form networks that trap particles of dirt and pollutants, so the crust looks black. Eventually the black crusts blister and spall off, revealing crumbling stone.When marble is exposed to acidic rain, sharp edges and carving details gradually become rounded.

The advantages of metal are that they are strong so that they can support weight easily. It also lasts longer than wood. Aluminum, steel and other metals need to be manually …separated from other recyclable material such as plastic and paper, according to Waste Care. Metals, especially aluminum, tend to degrade after each reuse cycle, so products using recycled metals can vary in quality, but most metals never reach a point where they are no longer recyclable. Recycling metals still uses energy, albeit about 95 percent less than new production.
From an engineering perspective, metal has a long list of advantages and disadvanages based on the application it's being used for. We can try and separate it into two very br…oad categories: structural uses and electrical uses. STRUCTURAL: Metal has been used as a structural element since the bronze age several millenia ago. The primary benefit of metal is it's ability to be bent and conformed to fit any given situation. The act of forming metal into a shape is called forging, whereas the act of joining two separate pieces of metal together is called welding. Metal, due to it's uniform nature, has excellent structural properties along all three axises. Metal is strong in tension, compression and in shear (longitudinal) strength. Concrete, on the other hand, tends to have excellent compressive strength but poor tension and shear strength. Composite materials are superb in tension but very poor in compression and somewhat unpredictable in shear. All metal rusts (forms oxide layers), although some rust slower than others, unlike stone or composite materials. One need only look at the pyramids of egypt to see how seemingly eternal stone can be. Composite materials, if kept out of the sun, could last just as long. Cheap metal tends to be very heavy (think cast iron). Metal can be very light if designed correctly (think comercial or military airplanes) but tend to cost a lot. Composites are slowly replacing metal in the aerospace industry for this reason. ELECTRICAL: To conduct electricity, one will almost always use metal wires, typically copper. There are currently no useful substitutes for metal. Exotic methods of electrical conduction do exist, such as graphene or silicon, but they are generally relegated to microscopic tasks. This is just a sample of the advantages and disadvantages of metal. Ask more specific questions and I'll generate a more specific list for you!
