However, instead of having a climate that is just a warmer version of Earth’s, Venus's surface and atmosphere are unbearable: clouds of sulphuric acid blanket the planet, while at ground level, it is hot enough to melt lead. Despite this, there is now a sign that Venus may harbour lif...
heating. The gold blanks are placed in boxes of powdered charcoal, which travel very slowly through a furnace on an endless chain. The transit takes about three hours. After immersion in a bath of dilute sulphuric acid, they are cleaned by being rolled in beechwood sawdust, and passed on ...
When cumene hydroperoxide is treated with dilute sulphuric acid,it gives phenol and acetone. How phenol and acetone are produced from cumene? Liquid-phase oxidation of cumene with molecular oxygen producescumene hydroperoxide, which is subsequently decomposed catalytically into phenol and acetone. The oxi...
PHOSHPORUS (P)Phosphorus-based fertilizers are produced from mined ores. Phosphate rock is primarily treated with sulphuric acid to produce phosphoric acid, which is either concentrated or mixed with ammonia to make a range of phosphate (P2O5) fertilizers. ...

Sulphuric acid is diluted by mixing concentrated acid with water in the ratio acid :water=2 :25.It is then further diluted by adding water so that the ratio weak acid :water=1 :4.How much concentrated acid is needed to make 300mL of the final mixture.以上求高人翻译. 扫码下载作业帮拍照...
A flooded lead acid battery is one in which the lead plates are submerged to the desired height in sulphuric acid and the gas whatever is created in the chemical reactions comes out of the battery. Whenever the acid level goes down we have to top up the battery with clean water (distal ...
of acid to the 6 ml. of the 5% solution, we will have a total of (6 + x) ml. of solution, and we want it to be 40% acid. in other words, the amount of acid in the final solution will be (6 + x) times 0.40 (40% in decimal form). Amount of...
Sulphuric acid (${ H }_{ 2 }{ SO }_{ 4 }$) is called the “King of Chemicals”because it is used in the preparation of a very large number of other useful chemicals such as hydrochloric acid, nitric acid, dyes, drugs etc. ... Sulfuric acid has the properties of strong acidic ...
