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
I’d say C. It more inconsistent than D.
D & C are quite close.
Answer: C
Answer:
I pretty sure it's the pH level 7
<u>Answer:</u> The given quantity is a type of length and is measured i the units of meters.
<u>Explanation:</u>
For the given quantity which is 4.8 meters, the unit is meters ans it the unit used to measure the length of an object.
For example: The height of the building is 150 meters. This statement means that the length of the building from the ground is 150 and it is measured in the units of meters.
Hence, the given quantity is a type of length and is measured i the units of meters.
