We first calculate the heat released:
Specific heat = 3.21 kJ/kgK
Heat released = heat absorbed by calorimeter
Heat absorbed = mcΔT
= 1.9 x 3.21 x 4.542
= 27.7 kJ
Now, we calculate the moles of hexane present:
Moles = mass / Mr
moles = 0.58 / (12 x 6 + 14)
= 0.0067
Heat of combustion = 27.7 / 0.0067 kJ/mol
ΔH(combustion) = 4,134.3 kJ / mol
Answer:
8.81849
Explanation:
i believe the whole number would be this but usually i round to the second decimal point, i dont know if you could do that in chemistry tho
option c is correct
number of electron in the outermost shell describe the reactivity if the outermost shell is completely filled its mean the reactivity of element is low and if it is completely filled then the element is highly reactive
Answer:
Balanced forces are those two forces acting in opposite directions on an object, and they are equal in size. Anytime if there is a balanced force on an object, the object stays still or it continues moving at the same speed and in the same direction is called a balanced force.
