The collision of one continental plate with another may produce what ?

Answer:

Mass = 427.05 g

Explanation:

Given data:

Formula units of sodium chloride = 4.38 ×10²⁴

Mass of NaCl = ?

Solution:

One mole contain formula units = 6.022 ×10²³

4.38×10²⁴ formula units × 1mol /6.022 ×10²³ formula units

0.73 ×10¹ mol

7.3 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 7.3 mol × 58.5 g/mol

Mass = 427.05 g

The medium through which a wave travels depends on the type of wave. Mechanical waves require a physical substance for propagation, while electromagnetic waves can travel through both material mediums and empty space due to their unique field-based nature.

The medium through which a wave travels is the substance or material that carries the energy of the wave from one place to another. Waves can propagate through a variety of mediums, and the nature of the medium has a significant impact on the characteristics of the wave.

In mechanical waves, such as sound waves and seismic waves, the medium is typically a material like air, water, or solid objects. In the case of sound waves, air molecules vibrate as the wave passes through, transmitting compressions and rarefactions that our ears perceive as sound. In seismic waves, the Earth's crust and mantle serve as the medium, with rocks transmitting the wave energy.

Electromagnetic waves, like light and radio waves, do not require a physical medium to travel through. They can propagate through a vacuum, such as space, as well as through materials like air, water, and glass. This is because electromagnetic waves consist of oscillating electric and magnetic fields that can interact with charged particles in matter or propagate freely through the vacuum of space.

Answer:

• The hydrogen exist as a liquid at -253 degree C.

Explanation:

• Hydrogen is found as a molecular form H2. In order to become liquid , it must be cooled below its critical temperature. It become liquid at -253 degree C or 423.17  degree F or 20.8 K.

• So hydrogen become liquid at -253 degree Celsius.
