Answer: Option (c) is the kinetic energy.
Explanation:
The kinetic energy present within the particles of a substance is known as thermal energy. Measure of average kinetic energy of particles of a substance is known as temperature.
Whereas heat defined as the transfer of thermal energy from a hot object to a cold object.
Enthalpy is defined as the heat gained or lost by a substance in a chemical reaction.
Thermodynamics is the study of relation between heat and work with chemical or physical changes.
Thus, we can conclude that a measure of kinetic energy of particle motion within a substance is temperature.
The famous bite mark evidence was crucial in this case because there was practically no other evidence to work from since Bundy was meticulous in cleaning up the scene.
Answer:
<h3>The answer is 0.25 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.505 × 10²³ Na atoms
We have
![n = \frac{1.505 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{1}{4} \\](https://tex.z-dn.net/?f=n%20%20%3D%20%5Cfrac%7B1.505%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20%20%5C%5C%20)
We have the final answer as
<h3>0.25 moles</h3>
Hope this helps you
You need 4 H2 molecules and 2 O2 molecules.
This is because water is H2O which is 2 Hydrogen and 1 Oxygen so if you want to make 4 water molecules, you’ll need 8 hydrogen and 4 oxygen.
Given H2 you need 4 because 4•2 is 8 and for O2 you need 2 because 2•2 is 4.
I hope this makes sense.
Ph of this solution would be 4
