Hi
only compound must two different atom.
Element have made by only single atom.
_________________________________
Compound:
A compound is formed when two or more elements chemically combine together. The elements react chemically and form chemical bonds between the atoms of the elements.
A mixture is a combination of two or more substances which are not chemically the same. ____________________________________
Homogeneous mixtures:
Homogeneous mixtures have uniform composition and appearance throughout .A homogeneous mixture is also called a true solution.
Example: sugar solution, ocean water, soft drinks, etc.
____________________________________
Heterogeneous mixtures:
Heterogeneous mixtures consist of different substances.
Examples: mixture of iron and sulphur, mixture of sand and table salt, etc.
so only elements are single atom.
all these are combination of atoms.
thanks for asking
The correct answer is <span>nebula forms → nebula collapses → protostar forms → fusion begins</span>
To find instantaneous velocity given a position vs. time graph is find the derivative at that given point. In other words, find the slope at that point.
So at t = 1s, the velocity is 5/2 m/s.
Hope this helps!
