I think the correct answer from the choices listed above would be the first option. The angle between the hydrogen atoms in water (H2O) is slightly less than expected for a tetrahedral shape. This is because of the extra electron repulsion from the lone pairs. Hope this helps.
The correct answer is decomposers.
The valence shell of Oxygen contains 6 electrons. Therefore, for completion of the octet, each Oxygen atom requires two electrons. This means that each atom will supply two electrons in the bond. So the correct option is B.
4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it
Answer:
Explanation:
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena.[1] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology). Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence. It is generally understood that they implicitly reflect, though they do not explicitly assert, causal relationships fundamental to reality, and are discovered rather than invented.[2]
