Answer:
6.02x10^23 atoms
Explanation:
From the background knowledge of Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 atoms. This implies that 1mole of carbon also contains 6.02x10^23 atoms.
1mole of carbon = 12g.
Therefore, 12g of carbon contains 6.02x10^23 atoms
<u>Answer</u>:
the law of conservation of mass is valid for all the following, except nuclear reactions.
<u>Explanation</u>:
the law of conservation of mass is valid for all the following, except nuclear reactions because some mass gets converted to energy.
Answer:
mass of S₈ = 96.1146 grams
Explanation:
The balanced equation that describe the reaction is as follows:
8 Fe + S₈ ..............> 8 FeS
From the equation, we can note that:
8 moles of Fe react with 1 mole of S₈
This means that:
8 * 55.8 grams of iron react with 8 * 32 grams of S₈.
To know the mass of S₈ that will react with 167.6 grams of Fe, we will simply do cross multiplication as follows:
mass of S₈ = (167.6 * 8 * 32) / (8 * 55.8)
mass of S₈ = 96.1146 grams
Hope this helps :)
The climate would become colder...
