Answer:
Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves
Explanation:
Answer:
C
Explanation:
Exothermic means that heat is released from the reaction
Okay, to do this you have to work with the relative molecular mass (RMM). You can get this from looking at the periodic table.
The RMM for the whole molecule is:
58.933 + (2 x 35.453) + (12 x 1.008) + (6 x 15.9994) = 237.96
Then you work out the RMM for water:
(2 x 1.008) + 15.9994 = 18.0154
As there are 6 moles of water in this molecule then multiply the RMM of H2O by 6 = 108.0924
Finally, divide the total H2O RMM by the total molecule RMM and multiply by 100 to get a percentage:
(108.0925 / 237.96) x 100 = 45.42%
