The reaction (of sodium hydroxide and citric acid) must be stirred. suggest a safety precaution that should be taken in this experiment, and explain why it is necessary. Pls answer this ASAP... Ill mark the person BRAINLIEST​

if you mean hydrogen and oxygen then water is the product

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
