C: salt is dissolved into freshwater
D: salt is dissolved into freshwater
F: frying changes the color and texture of an egg
G: ocean water evaporates to water vapor on a hot day
Answer: Luster: Metals are shiny when cut, scratched, or polished.
Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped.
Conductivity: Metals are excellent conductors of electricity and heat.
Explanation: Hope this helped!
4. True
5. The amplitude of the ripples decreases as the circumference of the circle increases.
<h3>What is a wave?</h3>
A wave is a disturbance that moves energy from one place to another.
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.
As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.

Answer:
12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.
Explanation:
initially
3.0 atm 0 0
At equilibrium
(3.0-2p) p 3p
Equilibrium partial pressure of nitrogen gas = p = 0.90 atm
The expression of a pressure equilibrium constant will be given by :
