A student described two properties of a substance shown below which of the following is true about the two properties described
in the table? x-the substances catches fire easily
y-a substance spontaneously explodes when exposed to other substances
a/ both are physical properties
b/both are chemical properties
c/x is a chemical property and y is a physical property
d/x is a physical property and y is a chemical property
The fact that the substance catches fire easily and explodes when it comes in contact with other materials is as a result of some kind of chemical reactions which are spontaneous and highly exothermic. Chemical properties of a substance are the properties it exhibits when it interacts chemically with other substances. The both properties described above are due to chemical interactions of the substances with other substances hence they are chemical properties.
catches fire easily, there is a chemical in the substance that reacts to the flame, and a key to it being a chemical property is when exposed to other substances, there is a chemical in the other substances that makes it chemically react
The simplest way to use the periodic table to identify an element is by looking for the element’s name or elemental symbol. The periodic table can be used to identify an element by looking for the element’s atomic number. The atomic number of an element is the number of protons found within the atoms of that element.
✏ Anions are negative in nature while cations are positive in nature. Together they come together by an attractive electrostatic force to form an ionic bond.
