Answer : The change in entropy is 
Explanation :
Formula used :
where,
= change in entropy = ?
m = mass of water = 1.00 kg
= heat of vaporization of water = 
T = temperature = 
Now put all the given values in the above formula, we get:
Therefore, the change in entropy is
Answer:
H+ and NO3- ions
Explanation:
The Pb²+ ions react with the SO4²‐ ions to form a solid precipitate, i.e. they bond together and undergo a phase change;
On the contrary, the H+ and NO3- ions are aqueous ions before the reaction and the same after the reaction, i.e. they don't change;
Hence, the H+ and NO3- ions are spectator ions
The way to do this type of question is to consider what changes and what doesn't, look at phase changes and oxidation state changes
Fluorine will always form an anion. That is because at its basic form, it is electronegative, which means that it attracts electrons who give it a negative charge. This is why it will form an anion.
Answer:
524.82 g Cl2
Explanation:
Balanced Equation:
2Al(s) + 3Cl(g) ⇒ 2AlCl (s)
Al: 26.982 g/mol Cl: 35.453 g/mol
266.28g Al x 1mol Al/ 26.982g Al x 3mol Cl2/ 2mol Al x
35.453g Cl2/ 1mol Cl2 = 524.82 g Cl2
