Answer:
Matter always takes space (or has volume).
Answer:
No
Explanation:
A chemical change is a change that involves a change in the chemical composition of matter. A new substance is formed. In a chemical change, new chemical and physical properties of the substance are formed. In a chemical change, the chemical and physical properties of the substance formed will be different from the original substance.
Chemical Property(s):
Toxicity.
Reactivity.
Types of chemical bonds formed.
Coordination number.
Oxidation states.
Flammability.
Heat of combustion.
Enthalpy of formation.
I know these are chemical properties because they are all a result of a chemical change. Chemical changes change the form of an object. For example, diluting orange juice by adding water changes it's ph from an acid to almost neutral.
Hope this helps!

Answer : The final pressure will be, 666.2 mmHg
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 790 mmHg
= final pressure = ?
= initial volume = 101.2 mL
= final volume = 120 mL
Now put all the given values in the above equation, we get:
Therefore, the final pressure will be, 666.2 mmHg
