Chemistry

Answer:

C-Electrical energy changed into mechanical energy

Explanation:

Energy, according to the law of conservation of energy, is said to neither be created or lost but only interchangeable from one form to another. Energy exists in different forms. The process by which one form of energy changes to another is called TRANSFORMATION of energy.

However, certain household appliances or devices bring about this transformation of energy. For example, in a case where Tony turns a fan on when his room becomes uncomfortably hot. The fan uses an electric source to get powered on, which then facilitates the blades of the fan to move fast in order to bring about a cool atmosphere.

The fan converts ELECTRICAL energy (electric source) into MECHANICAL energy (moving energy).

lara [203]

Answer:

bonding molecular orbital is lower in energy

antibonding molecular orbital is higher in energy

Explanation:

Electrons in bonding molecular orbitals help to hold the positively charged nuclei together, and they are always lower in energy than the original atomic orbitals.

Electrons in antibonding molecular orbitals are primarily located outside the internuclear region, leading to increased repulsions between the positively charged nuclei. They are always higher in energy than the parent atomic orbitals.

The gaseous product of a reaction is collected in a 25.0L container at 27.0 C. The pressure in the container is 3.0atm and the g
NeX [460]

Answer: The molar mass of the gas is 31.6 g/mol

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 3.0 atm

V = Volume of gas = 25.0 L

n = number of moles  = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =27.0^0C=(27.0+273)K=300K

n=\frac{PV}{RT}

n=\frac{3.0atm\times 25.0L}{0.0821 L atm/K mol\times 300K}=3.04moles

Moles =\frac{\text {given mass}}{\text {Molar mass}}

3.04=\frac{96.0g}{\text {Molar mass}}

{\text {Molar mass}}=31.6g/mol

The molar mass of the gas is 31.6 g/mol
