Explanation:
To determine whether a chemical formula represents a compound or element that will not combust, you need to consider the elements present in the formula and their respective properties.
First, check if the formula contains only one type of element. If it does, then it represents an element, and the question of whether it will combust or not is irrelevant, as elements do not combust.
If the formula contains two or more different elements, then it represents a compound. To determine if the compound will combust, you need to look at the properties of its constituent elements.
Some elements, such as noble gases (e.g., helium, neon, argon), have very low reactivity and are unlikely to combust under normal conditions. Therefore, if the compound contains only noble gases, it is unlikely to combust.
Other elements, such as metals, are more reactive and can combust under certain conditions, such as exposure to heat or oxygen. Therefore, if the compound contains a metal, you need to check the reactivity of that metal to determine if the compound will combust.
Similarly, non-metals can also be combustible under certain conditions, such as exposure to heat or other reactive substances. Therefore, if the compound contains a non-metal, you need to check the reactivity of that non-metal to determine if the compound will combust.
Overall, to determine if a compound or element will combust, you need to consider the properties of its constituent elements and any external conditions that may affect its reactivity.
