Is flammability a physical or chemical property quizlet?
is any ability to produce a change in the composition of matter. Flammability and reactivity are two examples of chemical properties.
Is nitrogen a more reactive element than oxygen?
Oxygen needs 2 more electrons to fill the outer shell, while nitrogen needs 3 electrons. Hence, it is much easier for oxygen to complete its octet, as compared to nitrogen and that is why, oxygen is more reactive than nitrogen.
Is the ability of matter to combine chemically with other substances?
Reactivity is the ability of matter to combine chemically with other substances. Some kinds of matter are extremely reactive; others are extremely unreactive.
What is flammability identify examples of flammable matter?
Flammability is the ability of matter to burn. When matter burns, it combines with oxygen and changes to different substances. Wood is an example of flammable matter, as seen in Figure below. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases.
Why is flammability a chemical property quizlet?
Boiling point, melting point, color, density. Describe why flammability is a chemical property rather than a physical property. Flammability is a chemical property because it can form a new substance.
Is heat of combustion a physical or chemical property?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
Why is oxygen more reactive than nitrogen explain?
oxygen has more electonegativity than Nitrogen and has tendancy to make octal of 8 electron in outer cell more strongly . Oxygen is also having more oxidating properties. thus it is more reactive than Nitrogen.
Why is oxygen more reactive than nitrogen?
O2 has two more electrons compared to N2, with extra 2 electrons in the higher energy anti-bonding orbitals known as Diradical. These electrons have higher energy and are unpaired; therefore, O2 is more reactive.
Why is the ability to burn a chemical property?
Flammability is the ability of matter to burn. When matter burns, it combines with oxygen and changes to different substances.
