Answer:
The volume increases,
Final volume is 2.1L
Explanation:
Based on Boyle's law, the absolute temperature of a gas is directly proportional to the volume of the gas.
As the balloon change increases its temperature, the volume increases
The Boyle's equation is:
V1T2 = V2T1
<em>Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
V1 = 2.0L
T2 = 35°C + 273.15 = 308.15K
V2 = ?
T1 = 25°C + 273.15 = 298.15K
2.0L*308.15K = V2*298.15K
2.1L = V2
<h3>Final volume is 2.1L</h3>

Molar mass is the amount grams that one mole weighs.
Explanation: You need to find the molar mass of NaCl which is the same as the amu on the periodic table in grams. So it is 22.99(Na) + 35.45(Cl) = 58.44
You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.
Finally, using the periodic table, again, you see that the molar mass of Na is 22.99.
Then using stoichiometry, you can find the grams of sodium.
100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Na)/ 1 mol (NaCl) * 22.99 (g of Na)/ 1 mol (Na)
which equals 39.339435 g of Na.
If you need to maintain significant figures the answer will be 40.

Answer: Bromine is Actually a Halogen!
Explanation: Bromine is in the 7th column of the Periodic Table. It needs that magic 8 valence electrons and it has 7.
Hoped that helped!
