Chlorine.
Chlorine is the 17th element and has a mass of 35.
Answer:
Answer 9 - 100 joules energy was at the producer level
Answer 10 - Remaining energy is used in metabolism
Explanation:
Answer 9
The energy at each trophic level is only 10% of the energy at its previous trophic level.
The energy at producer level is X
% of
Joules
Joules
Answer 10
Because the remaining 90% energy is utilized by the producer for its metabolism
Potassium 23.5g/39.0983g/mol = 0.601mol
The Ratio of reactants is 2 to 1 so (0.601mol)/2 = 0.3005mol
Therefore 0.3005mol of F2 is needed to find liters use
formula V = nRT/P (V)Volume = 22.41L
(T)Temperature = 273K or 0.0 Celsius
(P)Pressure = 1.0atm
<span>(R)value is always .08206 with atm n = 0.3005moles
(273)(.08206)(0.3005)/1 = V V = 6.7319 Liters</span>
<span>To convert the number of moles a compound to formula units, the conversion factor is Avogadro's number, 6.022 x10^23 formula units/ mol. In this case, we are given with 7.02 moles of sodium chloride. Hence the answer is 4.23 x 10^24 formula units.</span>
