metallurgy is nothing but extracting of metals when they are in their pure forms from their ores. LIKE gold, silver, platinum. ETC. Metals like iron are oxidized and are found in their ores. This is because metals are reactive with OXYGEN. Hope this helped you.Please mark as BRAINLIEST. THANK You!!:)

Explanation:TWO CL ATOMS for 1 Ca ATOM

Explanation:Pickles have some kind of ACIDS which generated naturally, DUE to which pickle's taste is sour. If it is stored in a metallic container,naturally generated acids will react with the metal & thus the compounds of metal can cause HARM to health. So pickles should not be stored in metal CONTAINERS.

SPECTRAL REGION :Arbitrary ranges of wavelength, some of them overlapping, into which the electromagnetic SPECTRUM is DIVIDED, according to the types of sources that are REQUIRED to produce and detect the various wavelengths, such as x-ray, ultraviolet, visible, infrared, or radio-frequency.

CaCO3+heat---------->CAO(s)+CO2(g)Explanation:it is a balanced EQUATION...please mark me the brainiest

Since at room temperature in pure water, that concentration is very CLOSE to 10-7M, so the pH is 7 . ... Moreover water has pH of 7 at temperature of 25 degree Celsius & it is "neutral" because the concentration of HYDROXIDE ions (OH-) is also 7 (pOH=7)and thus BALANCES out the concentration of hydrogen ions (pH=7).Please mark as brainliest

why do you think the author FINDS LAP of this question by easy method that WOULD

because the PLASTIC weight is LESS than the water weight but the metall is heavier than the water so thats why plastic REPLACED the OLD METAL buckets

O4---->ZnSO4+H2^Zn+2HCl--->ZnCl2+H2^Zn+NaCl--->no reaction CAUSE zinc is under sodium in the reactivity SERIES and cannot displace sodium. Zn+NaOH--> no reaction. same reason as above. him buddy I am. also a tenth grader. you can ask me any DOUBTS about any subject except geography. I will surely HELP. ☺

371+273=644kExplanation:It is because to change a temperature on the KELVIN scale to the celcius scale u have to subtract 273 from the given temperature, and to convert a temperature on the celcius scale to the Kelvin scale u have to ADD 273 to the given temperature........0°C= 273.16k....but we always take 273 as CONSTANT VALUE to subtract as well as for add.....I HOPE it will help you....... please mark me as brainlest... please, please, please....

Permanganate ION reacts with BROMIDE ion in the basic medium to give manganese dioxide and BROMATE ion. The balanced REACTION is:               2MnO₄¯ + Br¯ + H₂O → 2MnO₂ + BrO₃¯+ 2OH¯ Note: This is the ion-electron method to get the FINAL reaction.Explanation:

s two MOLECULES of Nitrogen atom. N2 MEANS two atoms of nitrogen in its ONE molecules. N2 shows that two nitrogen are bonded with covalent bond, and it become nitrogen gas WHEREAS 2N does not show any bond, it just show two number of nitrogen.
