nordsb [41]3 years ago
4 0

Answer:

The volume on the tank is 6, 20 L

Explanation:

We use the formula PV=nRT. We convert the units of pressure in kPa into atm and temperature in Celsius into Kelvin:

0°C=273K

101,325kPa---1 atm

275kPa --------x=(275kPax 1 atm)/101,325kPa= 2,71 atm

PV=nRT --> V=nRT/P

V= 0,750 mol x 0,082 l atm /K mol x 273 K/ 2, 71 atm= <em>6, 20 L</em>

What is sodium + oxygen when doing ionic bonds
Marta_Voda [28]

When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).

4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.

Under normal conditions, approximately 20% of the mixture is Na2O2.

6 Na + 2 O2 → 2 Na2O + Na2O2

hope it helps

In examples where the volume of a system is under constant pressure, which of
grin007 [14]
Answer:

D


Explanation:


At constant volume, the heat of reaction is equal to the change in the internal energy of the system. ... Most chemical reactions occur at constant pressure, so enthalpy is more often used to measure heats of reaction than internal energy.
