If the reactants of a reaction are HCI and NaOH, what could be a product? A. NO2,B. HCIO4,C. NaCl, D.Na2CO3

C. NaCl

Explanation: The answer is C because the products are water and salt. Hydrochloric acid is a strong acid and NaOH ( sodium hydroxide is also a strong acid) are the reactants.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

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.
