Li because its charge is +1.
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. ... This enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
Sounds can travel at approximately 6000 metres per second in some solids and at a quarter of this speed in water. This is because the molecules of solids are more tightly packed together than in liquids and those in liquids are more tightly packed than in gases.
Answer:
False
Explanation:
The temperature at which a solid melts, known as its melting point is highly characteristic of a compound and element.
The melting point of pure substances, compounds and elements is definite and not varied.
- Melting point is an intensive property of matter.
- It does not depend on the amount of matter present.
- It is an innate or intrinsic property of every matter.
- For example, no matter the volume or mass of water, it will always boil at 100°C, all things being equal.
Therefore, melting point of most solids is characteristic of compounds and elements.
In the following reaction,76.616 litre of oxygen will react
The answer is metamorphism
