Answer:
halogen is the name of group 17 on the table of elements
<span>C6H12 = 6x12 + 6x1 = 78.
The equation indicates that 2x78 = 156g benzene will produce 6542kJ.
Using proportions you can then calculate that
x/6542kJ = 7.9g / 156g
x = 331.3kJ = 331300J.
heat = mass x ΔT x 4.18J/g°
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9°
final temp = 21 + 14° = 35°C</span>

Answer:
Molarity NaOH = 0.0263M
Explanation:
Molarity Acid x Volume Acid = Molarity Base x Volume Base
12.5ml x 0.60M = 285ml x M(base)
M(base) = 12.5ml x 0.60M / 285ml = 0.0263M
A mole of anything contains 6.022x10^23 items. so we need to divide this
1.3 x 10^25 / 6.022 x 10^23 = 21.59 moles
