Answer:
<em>The correct option is C) H2SO4</em>
Explanation:
A molecule can be described as a substance which is made up of the same kind of atoms or element. For example, O₂, N₂ etc. Hence, option A is an example of an element.
A compound can be described as a substance which is made from different atoms or elements. For example, H2SO4 is made up of the elements hydrogen, oxygen, sulphur. Hence, option C represents an example of a compound.
Answer:
Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
Explanation:
Answer:
Accept 2 electrons
Explanation:
Elements are most stable when their valence shells are filled. Since sulflur lies within the third row in the p-block, it wants 8 valence electrons. However, according to the diagram, it only has 6 valence electrons. The simplest way to having a filled outermost shell is the one which involves the least amount of electrons being added or donated to the element. In this case, the fastest way to a stable element is by adding 2 valence electrons (6 + 2 = 8).
I say just guess. sorry, this is a hard question XD
