Determine whether each statement describes an electromagnetic wave, a mechanical wave, or both types of wave.
KiRa [710]

The question is incomplete, the complete question is;

Which statement describes a difference between electromagnetic and mechanical waves?

A. Mechanical waves cannot be longitudinal, but electromagnetic waves can.

B. Electromagnetic waves cannot move particles, but mechanical waves can.

C. Electromagnetic waves do not require a medium, but mechanical waves do.

D. Mechanical waves do not transfer energy, but electromagnetic waves do.

Answer:

Electromagnetic waves do not require a medium, but mechanical waves do.

Explanation:

A wave is defined as a disturbance along a medium which transfers energy. Waves may be classified as mechanical waves or electromagnetic waves based on their medium of propagation.

A mechanical wave requires a material medium for propagation. An example of a mechanical wave is sound waves. Sound waves are propagated in air.

Electromagnetic waves do not require a material medium for propagation. They can travel through space. An example of electromagnetic waves is light waves.

What mass of metallic silver can form from 1.147 g of copper metal according to equation b?
Arisa [49]

Answer:

        \large\boxed{\large\boxed{3.894g}}

Explanation:

From similar question, equation (b) is

Molecular Equation:

  • Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Net Ionic Equation:

  • Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s)

<u>1. Mole ratio:</u>

       \dfrac{2molAg(s)}{1molCu(s)}

<u>2. Convert 1.147 g of Cu(s) to moles:</u>

  • Atomic mass of Cu: 63.546g/mol

  • Number of moles = mass in grams / atomic mass

  • Number of moles = 1.147 g / 63.546 g/mol = 0.01805 mol Cu(s)

<u />

<u>3. Calculate the moles of Ag(s):</u>

    0.01805molCu(s)\times \dfrac{2molAg(s)}{1molCu(s)}=0.03610molAg(s)

<u />

<u>4. Convert 0.03610 mol Ag(s) to grams:</u>

  • Atomic mass of Ag(s) = 107.868g/mol

  • Mass = 0.03610mol × 107.868g/mol = 3.894g
