Answer:
Boyle's Law
Explanation:
This is a simple Boyle's law at work in this scenario.
Boyle's law is one of the gas law and it states that "The volume of a fixed mass of gas varies inversely as the pressure changes if temperature is constant".
This law was proposed by Robert Boyle.
- In a sealed syringe, the volume of gas begins to decrease as the plunger is pressed.
- Conversely, it becomes harder to press due to increasing pressure in the tube.
- The pressure pushes back the more it is applied.
- We can see that the higher pressure applied, the lower the volume of the gas.
This is clear cut practical of the Boyle's law.
The number of moles in a substance may be calculated using:
Moles = mass / molecular mass
The molecular mass of CH₂Cl₂ is:
12 + 2 * 1 + 2 * 35.5
= 85 grams / mole
Moles = 76.1 / 85
Moles = 0.895
There are 0.90 moles of CH₂Cl₂ present in 76.1 grams.
Question:
<em>how can compounds be classify?</em>
Answer:
<em>oxides contain one or more oxygen atoms, hydrides contain one or more hydrogen atoms, and halides contain one or more halogen atoms. Organic compounds are characterized as those compounds with a backbone of carbon atoms, and all the remaining compounds are classified as inorganic.</em>
Hope this helps!

Answer:
Yes
Explanation:
An object's weight can change, depending on its location, relative to the object of discussion. For example, we don't notice the change, but the farther away we are from Earth's core, the less we weigh. This means one would weigh more in a valley than they would on a mountain. The formula for gravity is F=G((msub1)(msub2)/r^2), where F is the force of attraction, G is the universal gravitational constant, msub1 is the mass of the first object, msub2 is the mass of the second object, and r is the distance between the two objects.
