Elements are SUBSTANCES that are made from one TYPE of ATOM. An ELEMENT cannot be broken down into any other substance. ... Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be SEPARATED by a chemical reaction.

um SILICATE + SULFURIC acid = potassium sulfate + hydrogenthis is the WORD EQUATION of2K+H2SO4=K2SO4+H2

lysis of Copper SulfateWhenever copper sulfate or CuSO4 is added to water, it gets dissolved in the water. As CuSO4 is an electrolyte, it splits into Cu+ + (cation) and SO4 − − (anion) ions and move freely in the solution.The Cu+ + ions (cation) will be attracted towards cathode i.e. the electrode connected to the negative TERMINAL of the battery. On reaching on the cathode, each Cu+ + ion will take electrons from it and becomes neutral copper atoms.In the above process, after taking electrons the neutral copper atoms get DEPOSITED on the cathode. At the same TIME, SO4 reacts with copper anode and becomes CuSO4 but in water it can not exist as single molecules instead of that CuSO4 will split into Cu+ +, SO4 − − and dissolve in water. So it can be concluded that, during electrolysis of copper sulfate with copper electrodes, copper is deposited on cathode and same amount of copper is removed from anode. If during electrolysis of copper sulfate, we use carbon electrode instead of copper or other metal electrodes, then electrolysis reactions will be little bit different. Actually SO4 can not react with carbon and in this case the SO4 will react with water of the solution and will form sulfuric acid and liberate oxygen.The process described above is known as electrolysis.Similarly the SO4 − − (anion) ions will be attracted by anode i.e. the electrode connected to the positive terminal of the battery. So SO4 − − ions will move towards anode where they give up two electrons and BECOME SO4 RADICAL.But since SO4 radical can not exist in the electrical neutral state, it will attack copper anode and will form copper sulfate.In the above process, after taking electrons the neutral copper atoms get deposited on the cathode. At the same time, SO4 reacts with copper anode and becomes CuSO4 but in water it can not exist as single molecules instead of that CuSO4 will split into Cu+ +, SO4 − − and dissolve in water. So it can be concluded that, during electrolysis of copper sulfate with copper electrodes, copper is deposited on cathode and same amount of copper is removed from anode. If during electrolysis of copper sulfate, we use carbon electrode instead of copper or other metal electrodes, then electrolysis reactions will be little bit different.

NDUSTRIES is a Japanese multinational company that specializes in fibers and textiles, performance chemicals, carbon fiber composite materials, ENVIRONMENT and ENGINEERING, life science, and others. In 2017, the company RECORDED a revenue of USD 19.65 billion with 45,762 employees globally.

Those reactions in which TWO compounds react by an exchange of ions to FORM two new compounds are called double displacement reactions. ... MANY double displacement reactions occur between ionic compounds that are dissolved in WATER. A double replacement REACTION is represented by the general equation.

Displacement reactions occur when a METAL from the electrochemical series is mixed with the IONS of a metal lower down in the electrochemical series. The atoms of the more reactive metal PUSH their ELECTRONS on to ions of the LESS reactive metal. An example can be seen below.

tion:A new study published today in Science Advances finds that if we burn all of the REMAINING fossil FUELS on EARTH, almost all of the ice in Antarctica will melt, potentially causing sea LEVELS to rise by as much as 200 feet–enough to drown most major cities in the world.

Mineral AcidCommonly used mineral acids are sulfuric acid, HYDROCHLORIC acid and NITRIC acid (they are also known as bench acids). Mineral acids range from superacids (PERCHLORIC acid) to very WEAK ones(boric acid).concentrated acidhydrochloric and sulfuric acid are the examples of concentrated acidsHOPE YOU UNDERSTAND THE ANSWER

actually you didn't have MENTIONED the options so that is why we can not send you perfect answer but here s some information about coal tar..Explanation:Coal tar. It is a black, thick liquid with unpleasant smell. ... Products obtained from coal tar are used as starting materials for manufacturing various SUBSTANCES used in everyday life and in industry, like synthetic DYES, drugs, explosives, perfumes, PLASTICS, PAINTS, photographic materials, roofing materials, etc.

rated acids = A concentrated acid is an acid which is in either PURE form or has a high CONCENTRATION. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and STRONG) acid.mineral acids = A mineral acid is defined as a water-soluble acid derived from INORGANIC minerals by chemical reaction as. opposed to organic acids (e.g. acetic acid, FORMIC acid).

I don't KNOW this ANSWER SORRY

= ( 25 + 273 ) K = 298 K2) 373°C = ( 373 + 273 ) K = 646 K__________________1) 290 K = ( 290 - 273 ) °C = 17 °C2) 473 K = ( 473 - 273 ) °C = 200°C

s are physically COMBINED structures that can be separated into their original COMPONENTS. A chemical substance is composed of ONE type of atom or molecule. A mixture is composed of different types of ATOMS or molecules that are not chemically BONDED.

chemical equation is the symbolic REPRESENTATION of a chemical reaction in the form of symbols and formulae, WHEREIN the reactant entities are GIVEN on the left-hand SIDE and the product entities on the right-hand side.

When ice (solid STATE) is heated, it melts and CHANGES to water (liquid state). When water is BOILED, it is converted to steam (gaseous state). The process can be REVERSED upon cooling. This justifies that these are the STATES of a substance

Ice actually has a very DIFFERENT structure than liquid water, in that the molecules align themselves in a regular LATTICE RATHER than more RANDOMLY as in the liquid form. It happens that the lattice arrangement allows water molecules to be more SPREAD out than in a liquid, and, thus, ice is less dense than water.

Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not CHANGE. It is used in many HOUSEHOLD electronics and in all devices that USE batteries.hope it helps you!!MARK me as the brainliest !!

mple, fractional distillation is used in oil REFINERIES to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points. The crude oil fractions with higher boiling points: have more carbon atoms. have higher MOLECULAR WEIGHTS.

thes are SPREAD up over the laundry line to GET them dried up QUICKLY. More SURFACE area of water exposes to the air because of SPREADING of clothes this speeds up the rate of evaporation and clothes are dried up quickly
