From the Avogadro's law one mole of a substance contains 6.022× 10^23 particles.
Therefore; 1 mole of water contains 6.022 × 10^23 molecules
Hence 1.7 moles will contain;
1.7 × 6.022 × 10^23 molecules
= 10.2374 × 10^23 molecules
= 1.024 ×10^24 molecules
≈ 1.02 × 10^24 molecules
Answer:
Aristotle believes that all material substances are matter and form.
Explanation:
If you remember from the four causes, the matter is one cause and form is another cause. Substance theory says that substances are the ultimate things in the universe

Answer: The half-reaction correctly shows the oxidation of iron
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
The oxidation of iron is represented as:
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
The reduction of iron is represented as:
