Question
Which of the following is true about compounds?1 pointthey can be physically separated into their component elementsthey have compositions that varythey have properties to those of their component elementsthey are substances made of two or more elements bonded together
Solution
The statement that is true about compounds is: "they are substances made of two or more elements bonded together."
Here's why:
-
Compounds cannot be physically separated into their component elements. They can only be separated by chemical means.
-
Compounds do not have compositions that vary. The ratio of the elements in a compound is always fixed. For example, water (H2O) always has two hydrogen atoms for every one oxygen atom.
-
Compounds often have different properties than their component elements. For example, sodium is a highly reactive metal and chlorine is a poisonous gas, but together they form table salt, which is safe to consume.
-
Compounds are indeed substances made of two or more elements that are chemically bonded together. This is the definition of a compound.
