Answer:
2,577°F
Also,
Boron: 3,769°F (2,076°C)
Neon: -415.5°F (-248.6°C)
Beryllium: 2,349°F (1,287°C)
D) 710 g
Step by Step:
Multiply 2.5 L by 2.0 M to solve for moles
2 mol/L • 2.5 L= 5 mol
Find formula weight of sodium sulfate
Na2SO4-142.04 g/mol
Na- 2(22.99)=45.98
S-32.06
O-4(16)=64
Multiply miles by formula weight
5 mole • 142.04 g/mol=710.2 g
We can describe a positive energetic process as any process which increases the internal energy of the system.
A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:
- Boiling an Egg
- Roasting food over a fire (the food is the reference system)
etc
Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.

Answer:
V = 15 L
Explanation:
PV = nRT
P = 1.29 atm, T= 355 K mass argon 40g/mol
n = mass/ molecular mass; n = 26.6 g/40 g/mol; n = 0.665 mol
V = (0,665 mol x 0.082 x 355 K) / 1.29 atm = 15 L
