d1i1m1o1n [39]
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>

5. A 4.44 L container holds 0.481 mol of O2 at 22.6°C. What is the pressure of the tank?
mamaluj [8]

Answer:  The pressure of the tank will be 2.63 atm

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = ?

V = Volume of gas = 4.44 L

n = number of moles = 0.481

R = gas constant =0.0821Latm/Kmol

T =temperature =22.6^0C=(22.6+273)K=295.6K

P=\frac{nRT}{V}

P=\frac{0.481mol\times 0.0821Latm/K mol\times 295.6K}{4.44L}=2.63atm

The pressure of the tank will be 2.63 atm

kow [346]

Owing to the arrangement of ions in NaCl, the structure has a high melting point and crystalline structure.

Ionic compounds are know to have a crystalline structure. This is because the ions in the compound are arranged into a crystal lattice. A crystal lattice gives a regular repeating structure of ions in the crystal.

As a result of this order in the crystal, the resultant sodium chloride structure has a high melting point and crystalline structure.
