Answer:
they are use to make tar, asphalt, paraffin wax, and lubricating oils.
Explanation:
There are several information's already given in the question. Based on those information's the answer can be easily determined.
M = <span>1.11 g CH4
C = </span>4.319 kJ g C⋅°
∆T = 35.65 - 24.85 degree centigrade
= 10.8 degree centigrade.
Then
∆H =−M ⋅ C ⋅∆T
= - 1.11 * 4.319 * 10.8
= - 51.776 kJ/<span>mol
I hope the procedure is clear enough for you to understand.</span>
Since hydrogen bonding is a stronger intermolecular force than van der Waals forces, more energy is required to separate the molecules of ethanol than the molecules of ethane. Thus ethanol has a higher melting point than ethane.
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are
important resources for a country’s energy mix, only nuclear power is
capable of producing large amounts of electricity 24 hours a day, 365
days a year.
For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC),
the U.S. Environmental Protection Agency and the U.S. departments of
Energy and Transportation—establish radiation protection regulations for
U.S. nuclear plants based on internationally recognized scientific
studies.
For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas:
reactor safety, radiation safety and security.
Answer:
<h3>The answer is 0.81 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 10.5 g
volume = 13 cm³
We have
We have the final answer as
<h3>0.81 g/cm³</h3>
Hope this helps you
