A. Valence electrons are the electrons on the outermost energy level. If you write out the electron configuration you add all of the electrons on the 3rd energy level.
1 mile = 5280 feet
So, 65 mph = 343,200 fph or 5,720 fpm or 125,840 feet in 22 minutes,
hope this helps :))
<span>Being that the number of moles of the unknown sample and any of the standard solutions is equal,
the formula M1V1 = M2V2 could work.
As the volumes of each are given as well as one of the molarities, the other molarities could be calculated. Another way would be to use the Beer-Lambert law, the equation is,
A=εlc
εl = A/c
Since A is absorbance (the y-axis) and c is the concentration (the x-axis) on the graph, y/x is rise over run, which is the slope. Since the slope and the absorbance of the unknown are known, the concentration can be calculated.
C = A/εl</span>
Biomass is a renewable source of fuel to produceenergy because: waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; and. properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops.<span>
