Answer : The energy required to melt 58.3 g of solid n-butane is, 4.66 kJ
Explanation :
First we have to calculate the moles of n-butane.

Given:
Molar mass of n-butane = 58.12 g/mole
Mass of n-butane = 58.3 g
Now put all the given values in the above expression, we get:

Now we have to calculate the energy required.

where,
Q = energy required
= enthalpy of fusion of solid n-butane = 4.66 kJ/mol
n = moles = 1.00 mol
Now put all the given values in the above expression, we get:

Thus, the energy required to melt 58.3 g of solid n-butane is, 4.66 kJ
A. Raccoons. They will be able to survive in a housing area just as well, or even better then they had in the forrest.
I hope that helped! :D
There are many ways to predict the properties of an element here's one example.As you move from left to right the electron affinity and ionization energy both increase .Since elements of the same family have similar characteristic,you can often predict the properties of another element in its family
Answer:
bio diesel
Explanation:
bio diesel is a recent development to supplement fossil fuels
The given acid is HCOOH, it is dissociated in water. This balanced equation represents the dissociation of HCOOH in water:
HCOOH + H2O ---> H+ + COOH-
The Ka of HCOOH is:
Ka = concentration of products / concentration of reactants
Ka = [COOH-] [H+] / [HCOOH]
