tion:Answer ❤️Building materials are what they are. CHEMISTRY isn't just limited to SCIENTISTS' labs and beakers. It is also used to create materials that grant buildings with enhanced building PERFORMANCE, enables energy and resource conservation, and facilitates materials that are EASY to install and maintain.hope it's helpful for you ☺️

You can write a REDOX reaction as two half-reactions, one showing the reduction process, and one showing the oxidation process. FE3+ is GAINING an electron to become Fe2+. Iron is therefore being reduced and tin is the reducing agent (causing iron to be reduced). The reduction half-reaction is: Fe3+(AQ) + e−→Fe2+(aq) Sn2+ is losing two electrons to become Sn4+. Tin is therefore being oxidised and iron is the oxidising agent (causing tin to be oxidised). The oxidation half-reaction is: Sn2+(aq)→Sn4+(aq) + 2e−Explanation:plzz mark me as a brainlist

A chemical formula SPECIFIES the number of atoms of each ELEMENT in a COMPOUND molecule, using the standard abbreviations for the chemical elements and numerical subscripts. For example, a water molecule has formula H2O INDICATING two hydrogen atoms bonded to one oxygen atom.Explanation:plzzz mark me brainlist...

In chemistry, the empirical formula of a CHEMICAL COMPOUND is the SIMPLEST positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, WOULD simply be SO, as is the empirical formula of disulfur dioxide, S2O2.Explanation:HOP it helps ☺️☺️please mark as the brainliest ☺️☺️☺️

rother...yukarıda ⬆⬆⬆⬆It has a pyramidal shape as shown, in which phosphorus is SP3 hybridised. 2) STRUCTURE of PCl5: It has a trigonal bipyramidal structure, in GASEOUS and liquid phases. The three equatorial P–Cl bonds are EQUIVALENT, while the two axial bonds are LONGER than equatorial bonds.

tion:Rigidity: I) solids are very rigid II) liquids are not rigid they are fluids iii) gases are ALSO fluidsCompressibility: I) solids are incompressible but in some CASES it is foreg. SPONGE ii) liquids are hard to compress iii) gases can be compressed very easily.shape: i) solids have fixed shape ii) liquids donot have fixed shape but volume iii) gases donot have fixed shape nor volumekinetic energy: solids have least kinetic energy liquids have intermediate kinetic energy. gases have most kinetic energy. DENSITY I) solids have high density ii) liquid have comparatively high density than gases iii) gases have very low density THANKS!

because of the REDOX PROCESS the IRON GETS rustedExplanation:

dly OUTBREAK has claimed lives of over 169,000 people and infected nearly 2,500,000 globally. The WHO has declared it a pandemic.The Health Ministry has CONFIRMED 18,985 cases of Covid-19 in India and 603 deaths so far. The disease has already claimed over 169,000 lives globally and infected close to 2,500,000 worldwide. The WHO has declared coronavirus outbreak as a pandemic.The coronavirus is a family of viruses that can cause a range of illnesses in HUMANS including common cold and more severe forms like SARS and MERS which are life-threatening. The virus is named after its shape which takes the form of a crown with protrusions around it and hence is known as coronavirus.The recent outbreak of coronavirus is believed to have occurred in a market for illegal wildlife in the central CHINESE city of Wuhan. Chinese health authorities and the WHO are investigating the outbreak of the recent coronavirus.

1. Zinc would be the cathode in this process.2. The electrolyte would be any SALT solution of COPPER like copper sulphate.3. Copper would be the anode in this process.4. Mass decreases as the reacting anode material becomes aqueous. Site of reduction: ELECTRONS are gained by the ions AROUND the cathode. These ions are the OXIDIZING agent because by taking electrons, they cause the anode to be oxidized.5. Production of hydrogen gas from water by electrolysis

Noble gas compounds are chemical compounds that include an element from the noble gases, group 18 of the periodic table. Although the noble gases are generally unreactive elements, many such compounds have been observed, particularly involving the element xenon. From the standpoint of chemistry, the noble gases may be divided into TWO groups:[citation needed] the relatively reactive krypton (ionisation energy 14.0 eV), xenon (12.1 eV), and radon (10.7 eV) on one side, and the very unreactive argon (15.8 eV), neon (21.6 eV), and helium (24.6 eV) on the other. Consistent with this classification, Kr, Xe, and Rn form compounds that can be isolated in bulk at or near standard temperature and PRESSURE (at least in principle for the highly radioactive radon), whereas He, Ne, Ar have been observed to form true chemical bonds using SPECTROSCOPIC techniques, but only when FROZEN into a noble gas matrix at temperatures of 40 K or LOWER, in supersonic jets of noble gas, or under extremely high pressures with metals.
