Answer : Salt and Sand are weighed and kept in different 50 Milliliter beakers because, the experiment is about studying and separating the homogeneous mixture. As salt crystals are cubic and sand grains are rounded oblong grains. If we mix it together it would require a physical method to separate them. So, before starting the experiment it needs to be weighed in different beakers.
Inorganic compounds make ionic bonds.
Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
- There are over a hundred elements known to date.
- Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
- Examples are copper, gold, iron
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
- There are several millions of compounds known.
- They are usually represented by chemical formulae.
As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.
