The correct answer to the question is D). Ability to combine with oxygen.
EXPLANATION:
Before going to answer this question, first we have to understand physical and chemical change.
The change or reaction is said to be physical if there will be no change in the chemical configuration of the substance. The property corresponding to this change is called physical property which won't change the configuration of the substance. It is measurable and simply denotes the physical states of a system.
A chemical change is a change in which a new substance is formed due to the chemical reaction. Here, both the reactants and products have different chemical configuration. The property corresponding to it is called chemical property.
As per our questions, hardness, boiling and ability to conduct electricity are the physical properties of a substance.
The ability to combine with oxygen is not a physical property. It is so because it will result into the formation of a new compound.
Hence, the correct answer to the question is the ability to combine with oxygen.
Answer:
as they go from solid to liquis to gas they heat up from thermal energy. that thermal energy then excites the molecules making them move faster causing them to change phases.
C. A cation as a cation is positively charged and when an atom loses an electron it forms a positive ion.
The answer should be C. Encourage his daughter to make friends with the new boy.
Hope this helps and have a happy new year
The energy of the electromagnetic spectrum is not used in mass spectrography to make measurements.
<h3>What is mass spectrometry?</h3>
In physics and chemistry, mass spectrometry refers to statistical analytical techniques that allow scientists to determine the mass distribution of various types of molecules based on their mass on a substance.
The energy of the electromagnetic spectrum is not used in mass spectrography to make measurements. The process of mass spectrometry is primarily based on the interaction of molecules with a beam of electrons (rather than photons) and the subsequent measurement.
Hence the energy of the electromagnetic spectrum is not used in mass spectrography to make measurements.
