Answer:
IR spectroscopy can be used to identify chemical structures are present in compounds.
Explanation:
Infrared spectroscopy is a technique in organic chemistry that can be use use to identify chemical structures present in compounds because it is base on the ability of different functional groups to adsorb infrared light.
This work by shinning the infrared lights into the organic compounds to be identified, some of the frequencies of the infrared lights are adsorbed by the compounds and its identify groups of atoms and molecules in the compound.
Answer:

Answer:
12.5mm
Explanation:
1cm = 10mm
so you need to multiply the 1.25 by 10 to get it in mm.
ideal gas law. but you are talking about moles of gas not miles
Answer:
1250N
Explanation:
This question is based on pascal's Law.
So By Pascal's Law
=
therefore =force on input piston =25N
= Force or weight on output person.
therefore after putting the values we get,
= (25x 1500)/30
=1250N
