2. Explain the steps for the extraction of copper from its sulphide ore. Write the balanced chemical equation for the reactions involved. |
|
Answer» In the extraction of copper from its Sulphide ORE, when ore is subjected to roasting some of it is oxidised to CU2O which reacts with the remaining Cu2S to give copper metal. In this process, Cu2S behaves as reducing agent. ☺Steps by Steps ☛Concentration of the ore (removal of unwanted metals and gangue to purify the ore) is done by Froth floatation METHOD as it is a sulphide ore. ☛Roasting: Copper glance (Cu2S) is roasted in the presence of air. ☛Reduction: Copper oxide is then heated in the absence of air. Write the balance.........xd ☺ By the end of this section, you will be able to:- ☛Derive chemical equations from narrative descriptions of chemical reactions. ☛Write and balance chemical equations in molecular, total ionic, and net ionic formats. ☛When atoms gain or lose ELECTRONS to yield ions, or COMBINE with other atoms to form molecules, their symbols are modified or combined to generate chemical formulas that appropriately represent these species. ☛Consider as an example the reaction between one methane molecule (CH4) and two diatomic oxygen molecules (O2) to produce one carbon dioxide molecule (CO2) and two water molecules (H2O).

Explain nitrogen cycle in detail |
Answer» ♡ DEAR *----* ✧༺♥༻✧✧༺♥༻✧✧༺♥༻✧ Nitrogen Cycle is a biogeochemical PROCESS through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and BACK into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, DECAY and putrefaction. PROCESS:-Fixation - Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb. Assimilation - This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. Ammonification - This is part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria TURN the nitrogen back into ammonium so it can reenter the nitrogen cycle. Denitrification - Extra nitrogen in the soil gets put back out into the air. There are special bacteria that perform this task as well. ✧༺♥༻✧✧༺♥༻✧✧༺♥༻✧ ■baazHere ■FollowMe ■Thanks~ 'don't copy my style :p' MARK ME AS BRAINLIEST♡ |

Answer» Answer: A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, which is separate from the other eukaryotic life kingdoms of plants and animals. A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, which is separate from the other eukaryotic life kingdoms of plants and animals.A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is CHITIN in their cell walls. Similar to animals, fungi are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not PHOTOSYNTHESIZE. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), which share a common ancestor (form a monophyletic group), an interpretation that is also strongly supported by molecular phylogenetics. This fungal group is distinct from the structurally similar MYXOMYCETES (slime molds) and oomycetes (water molds). The discipline of biology DEVOTED to the study of fungi is known as mycology (from the Greek μύκης mykes, mushroom). In the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants.

The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης mykes, mushroom). In the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants.Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic lifestyles in soil or on dead matter. Fungi include symbionts of plants, animals, or other fungi and also parasites. They may become noticeable when fruiting, either as mushrooms or as molds. Fungi perform an essential role in the decomposition of organic matter and have fundamental roles in nutrient cycling and exchange in the environment. They have long been used as a direct source of human food, in the form of mushrooms and truffles; as a leavening agent for bread; and in the fermentation of various food products, such as wine, beer, and soy sauce. Since the 1940s, fungi have been used for the production of antibiotics, and, more RECENTLY, various enzymes produced by fungi are used industrially and in detergents. Fungi are also used as biological pesticides to control weeds, plant diseases and insect pests. Many species produce bioactive compounds called mycotoxins, such as alkaloids and polyketides, that are toxic to animals including humans. The fruiting structures of a few species contain psychotropic compounds and are consumed recreationally or in traditional spiritual ceremonies. Fungi can break down manufactured materials and buildings, and become significant pathogens of humans and other animals. Losses of crops due to fungal diseases (e.g., rice blast disease) or food spoilage can have a large impact on human food supplies and local economies. |
